Blk update request i o error dev sda sector - Исправление ошибок и поиск оптимальных решений проблем

I just ordered a new server with a 1TB Samsung SSD. Installed Ubuntu 14.04.5 LTS.

After booting into the newly installed system, I see this in my dmesg and /var/lib/syslog. Output of grep error /var/log/syslog:

I am mostly concerned about these entries: blk_update_request: I/O error, dev sda, sector xxxxxxxxxxx

I ran badblocks -v /dev/sda which returned no errors.

I then ran smartctl --all /dev/sda, which also returned no errors. See output below. This one includes a short self test

My question is simple: What do you think might be wrong? The SSD should be brand new. It’s hard for me, in good conscience, to put this server into production with those errors in the logs. And the box is otherwise acting normal.

Источник

I have a Dell XPS (9360) running Ubuntu 16.04. About a year ago, it started black screening periodically and showing:

blk_update_request: I/O error, dev sda, sector 116437120
EXT4-fs error (device sda3): ext4_find_entry:1456: inode #340837
EXT4-fs error (sda3): previous I/O error to superblock detected

Often, I will be using Chrome and a page will fail to load, then the entire OS freezes,then I have to hold down the power button to get it to restart.

UPDATE:

UPDATE 2:
All MemTest tests passed

BIOS version is now 2.13.0

$ sudo dmidecode -s system-version

Здравствуйте!

Xubuntu 20.04
Внешний жёсткий диск на 500Гб в контейнере на один диск от AGE STAR, подключается через USB.
Мать ASUS возраст 10 лет.

Настроил автомонтирование этого внешнего диска.
Сначала физически включаю диск, потом комп.
Сразу при загрузке стоит работа бэкапа — BackinTime.
Всё нормально работало несколько месяцев (обновления системы за этот период не было).

Теперь (ничего вроде не менялось в системе) диск не монтируется:

— на уровне железа и в БИОСе он виден и нормально на этом этапе подключается при запуске;

— во время загрузки (ещё чёрно-белый экран, но режим монитора уже вроде бы графический) процесс загрузки надолго застревает — что-то с SATA, к внешнему диску идёт непрерывное обращение, после его физического выключения (выключателем) процесс загрузки продолжается нормально;

— если после завершения загрузки системы сразу попытаться снова включить этот (уже выключенный во время проблем с загрузкой — см.выше) внешний диск (выключателем), то он непрерывно работает, но ОС его не видит (диск непрерывно мигает как при обращении к нему, а GParted говорит, что не может получить статус такого устройства, называя конкретное устройство) (подождав, диск выключаем выключателем);

— если, не выключая компа, подождать некоторое время и снова включить выключателем внешний жёсткий диск — то он сам по себе тихо работает, но GParted его не видит вообще и даже не пытается искать;

— если теперь, не выключая компа, выключить выключателем внешний жёсткий диск и перемкнуть его в другой USB-разъём, то при его повторном включении он снова начинает долго мигать, а GParted опять говорит, что не может получить статус такого устройства.

Что это может быть:

1) Железо? Где? Мать, контейнер, диск?
2) ОС? Баг? Настройки?
3) Неудачная конфигруация бэкапа? Но почему это начинается ещё до запуска графической оболочки?

Как это исправить?

Спасибо

Hello, i have this problem on a server with 2HD Sata and ARECA 1200:

The server can’t access disks:

blk_update_request: I/O error, dev sda, sector 37568672
blk_update_request: I/O error, dev sda, sector 2242343324
blk_update_request: I/O error, dev sda, sector 603434343
arcmsr: executing bus reset eh… num_resets = 0, num_aborts =20
sd 0:0:0:0 rejecting I/O to offline device

But the volume raid is normal:
vsf info
———————————————————————————————————————
# Name Raid Name Level Capacity Ch/Id/Lun State
===============================================================================
1 ARC-1200-VOL#00 Raid Set # 00 Raid1+0 2000.0GB 00/00/00 Normal
===============================================================================
GuiErrMsg<0x00>: Success.
———————————————————————————————————————

And no error on the event log of the raid card.

Have i to do a scrub on the FS?
If yes, what is the best practoice on ZFS ? ( first time for me on zfs )

Thanks

SSD appears to be healthy but got blk_update_request: I/O error

I got the following kernel message

Something similar has also happened in February

Is my drive actually failing or am I experiencing some intermittent software issue?

Re: SSD appears to be healthy but got blk_update_request: I/O error

You should post the full output of ‘smartctl -a /dev/sda’ as it might contain hints about the problem. You should also check if there are any firmware updates for your drive as those might include stability fixes.

Re: SSD appears to be healthy but got blk_update_request: I/O error

Full smartctl output is below.

The drive is an OEM drive from another Dell laptop and corresponds to the Samsung 470 series retail drives. http://en.community.dell.com/support-fo … t/19378224 and http://en.community.dell.com/support-fo … 9#20753649 indicate that Dell does not offer firmware updates and Samsung 470 updates will not work on the PM810.

Re: SSD appears to be healthy but got blk_update_request: I/O error

Can you also post a full dmesg/journal output where you see the problem and also the output of ‘lspci -nnk’? Can you trigger the problem on demand? Do you remember what you where doing/program you were using when you noticed the problem?

The SSD itself has logged no errors so either the problem is between the SSD and the cpu or linux is asking the SSD to do something that it chokes on and times out. The full dmesg output might help in figuring out which is it.

Re: SSD appears to be healthy but got blk_update_request: I/O error

I have attached the output of lscpi -nnk and all journal output around where the problem occured.

I cannot trigger the problem on demand. I noticed the problem when I opened a terminal and noticed that the filesystem had become read-only. But that was several hours after the problem had occurred. Chromium was still working so I didn’t notice anything had went wrong at the time. The journal output seems to show that the problem occured around 15 min after I took the computer out of suspend and I started iftop at the same time. But I cannot reproduce the problem with iftop again.

Re: SSD appears to be healthy but got blk_update_request: I/O error

You could identify the file(s) on the sector(s) and try to trigger the problem by reading them (dd/cp)
See https://wiki.archlinux.org/index.php/Id … aged_files

The reproducability of certain bad blocks should hint whether this is a device or communication (kernel, memory, cable, temperature, …) issue

Re: SSD appears to be healthy but got blk_update_request: I/O error

I’m using lvm so block number calculations become more complicated but I followed this post https://serverfault.com/questions/51089 … 905#510905

Both of the sectors listed in the OP corresponds to inode 8, which given the low number and the fact that ncheck fails to return a path indicates that it is part of the journal. I already fscked the partition and everything appears to be working normally at the moment.
Reading the listed sectors with hdparm or dd did not produce any errors and hdparm returned consistent results.

Re: SSD appears to be healthy but got blk_update_request: I/O error

Suspend and hibernate on linux can be hit or miss, if anything keep regular backups and keep using your machine. If you manage to find a way to reliably trigger the problem you want to report it upstream as they are the ones who can better debug and solve or workaround the problem.

Hi,
I found a quite-reproducible problem (happens quite often!) with the following setup:

HW: Raspberry model B+, powered by its own 5V, 2A power supply
USB HUB 3.0 (Trascend TS-HUB3K), powered by its own 12V, 1.5A power supply (15W)
2 external hard disks (the problem happens also with just 1 hard disk!)
root@rasptorrent:~# cat /etc/os-release

Linux rasptorrent 3.18.5+ Add ifdef to make kernel compile without CONFIG_BCM2708_DT=y #744 PREEMPT Fri Jan 30 18:19:07 GMT 2015 armv6l GNU/Linux

(did «rpi-update» on Jan 31 2015)

HOW TO REPRODUCE: just producing traffic on the USB external drives at some point produces:

[ 1116.317108] sd 1:0:0:0: [sdb]  
[ 1116.317199] Result: hostbyte=0x07 driverbyte=0x00

[ 1116.317297] blk_update_request: I/O error, dev sdb, sector 326832904

(several times, for different sectors)

and the USB device (e.g., /dev/sdb1) is destroyed and a new dev node is created (e.g., /dev/sdc1).

The dwc_otg driver seems latest one:

root@rasptorrent:~# dmesg | grep dwc_otg

and it seems that «FIQ enabled», «NAK holdoff enabled» » FIQ split-transaction FSM enabled» features are there.

I’m going to attach the dmsg and lsusb outputs. Please let me know if I can try some fix.

Is there a firmware revision where this behaviour first started? I.e. can you identify which revision of firmware is the first bad one?

Unfortunately no. I have my raspberry only since a few days. Before buying the powered USB hub, it gave the same problem (back then it was using a raspbmc distribution with kernel 3.12 but the errors in dmesg were similar/identical). Moreover, after /dev/sd node recreation I could also hear the typical noise of the external hard drive having problems starting up… for this reason I thought the problems were due to insufficient power and thus I bought the USB hub.

Now the problem in dmesg is similar/identical but it doesn’t really seem a power issue: the hard disk stay on even when attached just to the USB hub and additionally, after the /dev/sd node recreation the hard disk emits no noise…

An additional thing: both the hard disk work just fine under Windows (and also under Linux on my workstation) even under heavy load… I think it must be something with dwc_otg driver…

Another note: I also tried to power everything from the USB hub (15W should be enough for the 2 external HDD and the raspberry) using a micro USB cable that goes from the hub to the raspberry micro-USB connection. The same problem happens.

Moreover, it also happens apparently randomly even when writing small files on the disk periodically (I have a script that writes 512B every 30 seconds)… for example just now I see:

that is, in idle conditions, after from second 38 to second 19013 no problem, then suddenly the USB failure.

Tried with another hard disk (again, over USB). I left it idle (mounted on the filesystem but without read/writes from userspace) for ~3days: no problem.
Then I started writing/reading:

By the way I’m a C/C++ developer… if you could point me to the right point of the code writing those

«sd 0:0:0:0: [sda]nResult: hostbyte=0x07 driverbyte=0x00»

I could help you with understanding the failure reason perhaps (althought I don’t know much about USB driver routines!)…

I have a similar issue

I’m not a linux guru, but trying my best to understand things , and solve where possible.
All your assistance is more then welcome

I confirm that this happens with Raspbery Pi 2 B running:
Linux 3.18.11-v7+ #777 SMP PREEMPT Sat Apr 11 17:30:37 BST 2015 armv7l GNU/Linux

I have a RAID attached via USB 3.0 (limited to 2.0 by RPi hardware) And it seems to happen under heavy traffic load. Is a 2x2TB in RAID 0 (total of 4TB drive). It fails when checking torrent downloads.

In my case it was 100% power related.

I was able to test the drive and generate different load conditions with the command ‘badblocks’ and tuning of the parameters -d -c- b ( fe: sudo badblocks -e 100 -v /dev/sda1 -s -c 32 -d 50). As a result the drive failed on different blocks or not at all. This was an indication that the individual blocks were ok.

Changing the powersupply of the RPI (2A) did not help neither.

After buying a USB3 Y-cable to power the drive from another USB port, all got solved and my drive is still running fine for weeks now. http://www.ebay.com/sch/i.html?_from=R40&_nkw=usb3+y-cable

Hope this helps your case too.

In my case, the USB RAID is self-powered, so the power should not be any problem.

Worth to try some badblocks tests to see if you can reproduce a failure? «sudo badblocks -e 100 -v /dev/sda1 -s» will test at maximum speed. If failure should occur each time in different blocks it would put the hard drive out of the scope.

After checking it with badblocks, after about 6 hours of checking it stopped after this error message:

The last two were me trying to do a ls in the mounted /dev/sda1, that now is called /dev/sdb1, so it won’t work.

By the way I still haven’t solved this problem. Just FYI: I see the same problem on both Raspberry PI model B+ and on my BeagleBone.

The hard disks triggering this problem are miscellaneous:

WDC WD5000LPVT (500 GB) enclosed in USB3 enclosure (reports itself as Norelsys NS1068)
Toshiba MQ01ABD050 (500 GB) enclosed in USB3 enclosure (reports itself as Norelsys NS106X)
Toshiba MQ01UBD100 (1 TB) with its own Toshiba USB3 enclosure

It may help if you write down the manufacturers and model names of the hard disks that trigger this problem (the «Result: hostbyte=* driverbyte=*» error message). Thanks!

Another comment: on my desktop computer running Ubuntu Trusty 14.04 no problem are reported when transferring large files between the disks reported above.

I’m not sure if it is related, however I’ll share anyway, since it can help someone.

When I was assembling my rpi file server, with two external hard drives plugged into an usb hub, both in those cheap enclosures, I was not be able to use them till I’ve used a power source of 5.3 V (to the usb hub), instead 5.0 V. So, I strongly recommend trying a higher voltage power source.

I have the same error using a WD 2TB USB3 disk, refer https://www.google.de/url?url=https://github.com/raspberrypi/linux/issues/885&rct=j&q=&esrc=s&sa=U&ei=qz82VZIhwaewAYDNgKAN&ved=0CBoQFjAB&sig2=OFhTaepwrroA5QRZuaWnUQ&usg=AFQjCNEzwcQ-hGcApolnu3RnIxP6Et4JdA

I actually have two Pi’s, each with same model USB HDD. 1st on is a Model B, 2nd one a Model 2B. Works fine on the older Model B, but the problem occurs on the newer Model 2 B.

BlindFreddy :
As stated before I’m not a specialist and my incident was power related. Reading your case I can only assist you to suggest some validations if your case isn’t power related too. Interestiging in that you have 2 RPI and 2 drives.

Are you able to change the drives from one RPI to each other.

Are you able to switch the power supply from one RPI to another

I believe Western Digital Passport drive gets the power from the USB, are you able to use a y-cable to power the failing drive externally (http://www.ebay.com/sch/i.html?_from=R40&_nkw=usb3+y-cable).

Does ‘sudo badblocks -e 100 -v /dev/sda1 -s’ runs fine or fails each time at the same point ?

The result of the test should perhaps show it the issue remains related to HD, RPI/OS version or power supply .

I don’t think it’s a power related error, since it worked perfectly in Raspberry Pi B, but it’s not working in Raspberry Pi 2 B. In any case, I might be able to try it again in Raspberry Pi B this weekend.

Yes, I can try it out using Pi B and Pi 2B and the two drives. I cannot try external power y-cable — don’t have one and also, since it has the drive has been working flawelessly on Pi B using internal power for well over a year, I think it is reasonable to expect it to work on Pi 2B.

Pi2 can use more power that Pi1, so I don’t think you can infer a power supply that is good for Pi1 is necessarily good for Pi2.

But in my case, the HDD RAID is self powered.

FYI, Adafruit have released a tutorial on adding an external HDD to a Pi, and they say:

The Raspberry Pi doesn’t have enough power to run most external hard drives or SSDs, so unless you have a drive with its own power supply, you’ll probably need a powered USB hub.

In my case, I’m using a powered USB hub (certified for USB 3.0, so that the
hub comes with a 15W power adapter)… all these issues make me feel that
it’s not really a power supply issue.

Perhaps to be sure the only way would be attaching an oscope to the USB
lines and see directly if the signal strength over USB D+ and D- lines is
good enough or not.

Honestly, I suspect some driver issue, either on Linux driver side or in
the hard disk / USB adaptor firmware.
Probably Windows is capable of handling such situation (indeed most vendors
only test their hard drives with Windows only), but Linux no.

Just my 2cents,
Francesco M.

#777 (comment).

Hi all, I’m having this very same problem but not on a raspberry, just a regular intel computer. My HDD is attached to a SATA-to-USB adaptor and it shows this exact same behaviour. It actually started after an update to the system, including a Kernel update, so the problem must be there, since no hardware was changed, and I even tested two different linux distros (opensuse 13.2 & ubuntu 15.04) both does exaclty the same. Today I will try a regression to an older linux distro an see if the problem «solves» just to be sure of this.
Hope this narrows the source of the problem a litte.

Regards!

I can confirm (almost 100% sure) that it is not power related. I have bought a 5V 2A PSU for the Raspberry Pi 2 and a powered USB hub to connect the storage there. As I said before the storage is self powered, so there is no doubt that all has enough power. But it continues to fail. This time after more than 2 hours of use, but it disconects the device and adds it as a new drive (even if UUID is the same).

In my change to the USB hub I also ran into #824. In any case I could do a workaround for that (changing the root delay, as said in the issue comments). The thing is that as we have seen, under heavy load, the device simply disapears from /dev.

Here is, again the dmesg:

You might want to try adding max_usb_current=1 to your /boot/config.txt (context).

I think cause is heat.
Do you set heatsink on CPU and LAN9514?
LAN9514 is USB and Ethernet controller.

Neither of those devices requires a heatsink.

same question. model 2 B with USB 3.0 HUB. The problem is the USB3.0. 2.0 works well.

Also seeing this issue with a rpi model 2B & USB 3 self-powered hub, and 4GB USB seagate drive.

I uses 2 external disks and only one disk has the same problem.
Problem is occur on IPTime 3035 external disk case + HDD.
It has external power adapter, so I connected the disk directly to rpi.
I recently bought rpi3 and this issue was not reproduced on my previous rpi1 B+
I guess this could be related to heat, its hot summer here and it seems to be reproduced after some time after reboot.

Having the same issue on a virused USB Flash Kingston DT101 G2 (16GiB). I think the virus affected its boot sectors and now the Kernel is unable to read the size of the device in order to mount it properly.

Hi from the OpenWRT community! ✋
I was curious to if a solution was found to this problem?
I’m having the exact same problem on my device on kernel versions: 3.18.20 to 3.18.36 !
It seems to be related to the SD-card. Replacing my SD-card with a USB-thumb drive (mounted exactly similar), «fixes» the problem. But i miss my SD-card. 😭

When it happens very similar error-messages as above shows, and the sd-card disconnects from the device, and then re-appears a second later with a new identifier each time (/dev/sda -> /dev/sdb — /dev/sdc)
Running badblocks on the sd-card will also trigger it each time.
Very often when simply reading/writing to the device it happens, but never on standby.

I know this thread is about Raspberry Pi, not OpenWRT. But i had to ask if you guys found a solution, because i’m pretty desperate to get this fixed. 😃

For everyone experiencing random device disconnects, what happens if you put a USB hub between the Pi and the device in question?

Same problem here with
OSMC (up to date)
RaspberryPi 3
USB 2.0 Hub (Hama 1 to 4 — https://de.hama.com/00078472/hama-usb-20-hub-14-with-power-supply-black-cardboard-box?srcLang=0&targetLang=1 )

Details about the usb hub, maybe to identify the chipset. Also have a look at the max power of 100mA, the drives have a max power up to 500mA. Maybe this would explain, why some hubs works (especially some chipsets) and others not, and why sometimes it seems, that a better power supply would do the trick also.:

u see now sdc1 because the target drive, with ext4 get auto remounted as read only.

a manually remount did the trick for a few hours copying data…

@P33M Is this covered by other USB issues? Can it be closed?

hi, I explain about my case.

１ｓｔ:»environment»
raspberry pi 2 model B.
SSD connect to USB port.
OS ubuntu for raspberry pi.

Test case is copy 50GB(1000 files) to SSD from PC.
error : Buffer I/O error on dev sdxx.

2nd:»environment»
raspberry pi 2 model B.(not 1st device, it mean the i have two raspberry pi. )
SSD connect to USB port.(device is same as １ｓｔ)
OS ubuntu for raspberry pi.(device is same as １ｓｔ)

Test case is copy 50GB(1000 files) to SSD from PC.
It worked very well.

Different point is raspberry pi only. other all environment same as 1st.
So, In my understanding it is a problem of raspberry pi HW.

Same issue for me, and solved.
It was a power issue : My raspberry and hard drive (2Tb) were both powered through an usb hub-powered (2.5A).
I had a DC power switch (jack) to the hub to easily power on and off my raspberry. The switch was actually too resistent to let pass enough power to the whole thing. It was working with a 1TB hard drive, but not with my brand new 2TB.
After deleting the switch and directly powering the hub with the DC adaptor, problem has disappeared.

Hope it helps some of you.

Sry for my poor english.

This issue will be closed within 30 days unless further interactions are posted. If you wish this issue to remain open, please add a comment. A closed issue may be reopened if requested.

I would like this issue to remain open, as i’ve yet to find a fix for it anywhere. And that would be really awesome to get.
But if it needs to be closed, i also respect that.

@adde88 I presume that you are using an up to date Raspbian, and that everything is sufficiently well powered?

No, i’m not. That’s why i’m ok with you closing it.
The reason i wanted this open is because i’m having the exact same issue on another emedded device, running OpenWRT. (Me and alot of other people)
My device is running the exact same version of the kernel.
Based on that my gut is telling me that there’s «something» with this kernel version.
I also haven’t found another place where this issue has been discussed.
So therefore i was hoping that someone found what’s the cause of this. If it’s power-related, or a kernel-bug, anything would be interesting to find out. As it could lead to the bug being fixed on our devices as well.

But again, i respect your decision to close this, considering my issue is not directly related to the Raspberry Pi.

OK, since this is no longer an RPi issue (as far as I can tell), I’ll close it.

Note that closed issues can still be searched and commented on.

FWIW I have just «discovered» the same problem. I am running latest Raspbian Stretch Linux version 4.14.62-v7+, on Raspberry Pi 3 Model B Rev 1.2. When connecting my brand new USB<>SATA adapter cable called «Qicent» (https://www.amazon.de/gp/product/B01MAWO4V2) which is identified by kernel log as:

What I find interesting is MaxPower 2mA.

In my case I am running two additional USB devices on my RPi 3B:
ZWave USB stick
64GB flash stick
so the RPi is pretty loaded (uses 2.5A PS — at least it is written there), but what I find interesting is that I observe the complete USB reset in kernel, when I connect the Qicent cable even without any disk attached, just the adapter is enough to break it down. On the other hand, disconnecting the cable does not do anything to the system. Rebooting with the cable already connected and with the disk attached is also fine.

Below is the dmesg from the crashing system, which shows that once the new USB device is attached, current devices become unavailable and then they are re-enumerated, which moves my USB flash stick from /dev/sda to /dev/sdb and completely confuses the system.

Could it be the USB-SATA adapter that’s buggy? I’ve had severe issues with a Revoltec enclosure, several dead sectors when using it. Can’t read the bloody chip, but I think it’s a Revoltec RS076 enclosure.

Could it be the USB-SATA adapter that’s buggy?

It could, but when I tried it in normal PC (Windows 7), there was no problem (but I probably did not have other devices on the same USB hub either).
The fact that it completely resets the USB interface points to the hardware bug, rather than software, but whether it is the bridge chip, or the USB hub in RPi, I do not know, nor if it is really HW bug, or some linux kernel mechanism.

I’ve done ALOT of debugging on my OpenWRT device. (Pineapple NANO)
I managed to cross-compile the latest kernel (4.14.81) in the hope that this would squash the bug.
But the same error keeps dropping. Though i’m noticing a pattern.

In ALL of the error messages it failed while using the SCSI OPCODE: 0x28 (READ)
So, i’m currently trying to locate exactly which driver is failing, as the kernel have loaded both OHCI and EHCI.
I also tried to uninstall the «scsci-generic» module.
It’s not using any MMC driver to manage the SD-card.

Here’s some info about the device from lsusb:

1. First detect the failure

[[email protected] ~]# badblocks -s -v -o /root/badblocks.log /dev/sda
Checking blocks 0 to 586061784
Checking for bad blocks (read-only test): done                                
Pass completed, 173 bad blocks found.

smartctl -a /dev/sda3 (Quickly detect bad sectors on the hard disk, see if there are errors behind read and write)

2. Logic bad sectors repair method

①, badblocks -s -w /dev/sda END START (END represents the end of the sector that needs to be repaired, START represents the beginning of the sector that needs to be repaired)
②, fsck -a /dev/sda

After repairing, use badblocks -s -v -o /root/bb.log /dev/sda to monitor whether there are any bad sectors. If the bad sectors still exist, it means that the bad sectors are hard disk bad sectors. The hard disk bad sectors should be isolated. Firstly, record the detected bad sectors of the hard disk and then divide the sectors where the hard disk bad sectors are located in a partition (the size is generally larger than the size of the bad sector), and the divided bad sector partitions are not used. Can achieve the purpose of isolation

3. 0 bad track and hard drive (ready to change hard drive)

The repair method for bad tracks of track 0 is to isolate track 0, and when using fdsk to divide the area, start dividing the area from track 1.

На этот вопрос уже есть ответ: Как проверить целостность носителя данных (жесткий диск или флэш-диск)? 4 ответа

Всего новичков. Немного узнать о fsck на лету, но то, что я нахожу до сих пор, похоже, не очень сильно, когда я его применяю. Каким будет следующий шаг из этой подсказки для исправления ошибок, возникающих при загрузке?

Я боюсь, что ваш жесткий диск имеет badblocks или он не работает. Вы видите это сообщение: blk_update_request: I/O error, dev sda, sector 2048? Это означает, что читать этот сектор с физического устройства невозможно.

Вам нужно загрузиться с LiveCD и проверить, что вы управляете:

$ sudo smartctl -HA /dev/sda

и проверить строку SMART overall-health self-assessment test result: PASSED, а строка Reallocated_Sector_Ct должна содержать 0 в RAW_VALUE.

Если самотестирование SMART PASSED, вы можете попробовать «переназначить» badblocks с помощью инструмента badblocks:

$ sudo badblocks -svo ~/msg.log /dev/sda

и запустить fsck после:

$ sudo fsck -a /dev/sda1

Если самотестирование SMART FAILED, вам нужно заменить ваш жесткий диск.

PS: Все эти шаги вы должны выполнить с сеанса LiveCD. И вы должны заменить /dev/sda на свой диск.

Update [11.11.2017]: Итак, я проверил один из моих старых HHD с badblocks, и у меня есть эти сообщения в моем syslog:

Итак, все сообщения о ошибках ввода-вывода поступают из ядра. Самое интересное, что я нашел в этой строке:

Nov 10 13:46:55 router kernel: [ 121.380346] sd 1:0:1:0: [sdb] tag#0 Add. Sense: Unrecovered read error - auto reallocate failed

Как я понял, это декодированное сообщение с прошивки диска. Похоже, что прошивка обнаружила ошибку чтения и попыталась перераспределить сектор и с ним не справилась. Следовательно, в нашем случае badblocks ничего не делал, кроме чтения всех секторов, и мы могли бы заменить его на dd if=/dev/sdX of=/dev/null.

И теперь я полностью взволнован с sudodus. Наиболее подходящим решением является:

sudo e2fsck -cfk /dev/sdxn

При загрузке Linux на оборудование с включенным контроллером дисковода гибких дисков появится следующее приглашение:
blk_update_request: I/O error, dev fd0, sector 0

Устраните сообщение об ошибке, закрыв модуль дисковода гибких дисков:

#
# /etc/modprobe.d/modprobe.conf
#
blacklist floppy

Попытка 2:

 При dmesg появляется следующее сообщение, указывающее на проблему с диском Info fld = 0x139066d0

1. Сначала определите поврежденные сектора

badblocks -s -v -o /root/bb.log / dev / sda сохранить результат в bb.log

[[email protected] ~]# badblocks -s -v -o /root/badblocks.log /dev/sda
Checking blocks 0 to 586061784
Checking for bad blocks (read-only test): done                                
Pass completed, 173 bad blocks found.

smartctl -a / dev / sda3 (быстрое обнаружение сбойных секторов на жестком диске, проверка наличия ошибок чтения и записи)

2. Метод исправления сбойных секторов логики

①, badblocks -s -w / dev / sda END START (END представляет конец сектора, который необходимо восстановить, а START представляет начало сектора, который необходимо восстановить)
②、fsck -a /dev/sda

После исправления используйте badblocks -s -v -o /root/bb.log / dev / sda, чтобы отслеживать наличие сбойных секторов. Если сбойные сектора все еще существуют, это означает, что сбойные сектора являются сбойными секторами жесткого диска. Плохие секторы жесткого диска должны быть изолированы. Во-первых, запишите обнаруженные поврежденные сектора жесткого диска, а затем разделите сектора, в которых поврежденные сектора жесткого диска расположены в разделе (размер обычно больше, чем размер поврежденных секторов), а разделенные поврежденные сектора не используются. Может достичь цели изоляции

3. 0 плохая дорожка и жесткий диск (готов к замене жесткого диска)

Метод исправления плохой дорожки дорожки 0 состоит в том, чтобы изолировать дорожку 0. При использовании fdsk для разделения области начните разделять область с дорожки 1.

Если на жестком диске есть битые сектора, его можно только изолировать, но не отремонтировать.
