Error mounting dev sdb1 at media unknown filesystem type ntfs

NTFS (New Technology File System) is a proprietary journaling file system developed by Microsoft. Starting with Windows NT 3.1, it is the default file system of the Windows NT family.

The ntfs3 kernel driver provides read and write support for the file system.

Tips and tricks

Improving performance

You can enable some mount(8) options to improve the performance:

• noatime – can speed up the file system operations.
• prealloc – decreases fragmentation in case of parallel write operations (most useful for HDD).

Known issues

Explicit file system type required to mount

ntfs3 requires the file system type to mount.

To be able to mount the file system, specify its type as ntfs3 . For example, using mount(8) ‘s -t / —types option:

Troubleshooting

unknown filesystem type ‘ntfs’

When mounting NTFS, you can encounter an error such as:

If you want to use ntfs3 as the default driver for ntfs partitions, such udev rule does the trick:

Although, this method is not recommended and can confuse some 3rd party tools.

udisks support

udisks supports NTFS3, but has some issues at the moment. See udisks ntfs3 PR and issue 932.

Issues can manifest as the following errors, when the NTFS3 driver is used because NTFS-3G is not installed, but with mount options that it does not recognize:

The second error in particular can be encountered with Dolphin.

As a workaround, add a such option to /etc/udisks2/mount_options.conf in [defaults] section:

Unable to mount with ntfs3 with partition marked dirty

When trying to mount a good NTFS partition (i.e. which successfully mounts with NTFS-3G and for which ntfsfix —no-action does not report any error), you may get the following error:

ntfs3 will not mount a partition where the volume is marked dirty without the force option. dmesg explicitly helps recognizing the situation, saying:

You can try passing the —clear-dirty argument to ntfsfix to clean it. [1]

Как монтировать NTFS в Linux

Инструкция на примере Linux CentOS 7.

Установка компонентов

Для начала необходимо установить пакет ntfs-3g. В противном случае, при попытке запустить команду на монтирование раздела NTFS мы получим ошибку mount: unknown filesystem type ‘ntfs’.

Сначала устанавливаем расширенный репозиторий:

yum install epel-release

Затем сам пакет ntfs-3g

yum install ntfs-3g

После установки данного пакета в системе появятся дополнительные команды mount.ntfs-fuse и mount.ntfs-3g., а также команда mount распознает опцию -t ntfs.

Ручное монтирование

Монтирование NTFS на чтение и запись выполняется любой из трех команд:

mount -t ntfs /dev/sdb1 /mnt

mount -t ntfs-3g /dev/sdb1 /mnt

mount.ntfs-3g /dev/sdb1 /mnt

* в данном примере, примотировано устройство /dev/sdb1 в раздел /mnt. Понять, какой устройство нужно монтировать можно при помощи команды fdisk -l

Автоматическое монтирование

Чтобы раздел автоматически монтировался при перезапуске компьютера, открываем на редактирование файл:

/dev/sdb1 /mnt ntfs defaults 0 0

* в данном примере мы раздел /dev/sdb1 будем монтировать в каталог /mnt.

Чтобы применить настройку и проверить ее, вводим:

How to Solve Unknown Filesystem Type NTFS On Linux?

By default, the file format used by Windows OS is NTFS. Based on that many people format their USB flash disk using this file format. If we insert this USB Flash disk into the Linux OS server, then sometimes there is an error like the one below when mounting to the /root/sysadmin folder:

Error when mounting USB Flash disk

Problem

How to solve unknown filesystem type NTFS on Linux?

Solution

In the previous article, we explained how to format and mount an external device on Linux. If our USB flash disk or external HDD uses the NTFS file system, sometimes there are some Linux distros that cannot recognize the file system so an error will appear as shown in the image above when mounting. Therefore, we have to install the package below so that the Linux distro can recognize the NTFS file system:

RedHat distribution (CentOS, AlmaLinux, RockyLinux)

Do the mounting again and it should mount the external device as shown in the image below:

Mount USB Flash disk after installing the package

Note

I’ve tried 4 Linux distributions (Ubuntu, Debian, OpenSUSE, and RockyLinux), there are 2 distros that support NTFS by default, namely Ubuntu and OpenSUSE. While the other 2 distros must first install the above packages in order to support NTFS.

How To Mount A Windows NTFS Disk In Linux

The New Technology File System (NTFS) is a proprietary file system created by Microsoft and is used extensively in Microsoft’s Windows operating systems.

By default most Linux distributions are not able to mount NTFS, however it is possible to install a driver that allows us to do this so that we can read and write data to an NTFS disk.

In this example I have attached the VMDK file from a Windows based virtual machine to a CentOS 7 Linux virtual machine.

When we run ‘fdisk -l’ we can see that the disk is recognized (after a system reboot), however it is not yet mounted for us to access the data. We can see the primary disk for the Linux system /dev/sda, while /dev/sdb is our 1GB NTFS disk which has the /dev/sdb1 NTFS partition.

By default when I try to mount the NTFS disk, we get the below error.

Install Required Packages

In order to perform the mount, we need to install the ntfs-3g package, which is a Linux NTFS userspace driver. This package comes from EPEL if you’re using CentOS/RHEL, so if you have not yet configured your system to use the EPEL repository, run the following command.

Now we should be able to install the ntfs-3g package from the EPEL repository.

Otherwise if you’re using Ubuntu/Debian, you should just be able to run ‘apt-get install ntfs-3g’ straight away. In my Debian 8 installation it was already available so I was able to mount NTFS without any problems.

Mount The NTFS Disk

We can now successfully perform the mount without any errors.

We can confirm that the NTFS disk is now seen as mounted by the operating system.

At this point you should be able to read and write data on the mounted NTFS disk.

Automatically Mount NTFS

We can create an entry in the /etc/fstab file so that our NTFS disk will automatically mount on system boot. Below is an example of the entry that I have placed into my fstab file. This will mount the disk to the /ntfs directory.

Once this configuration has been added, the NTFS disk should mount automatically on system boot. Before performing a reboot, it is recommended to first run the ‘mount -a’ command and confirm that the disk mounts without errors. If there are errors that happen during boot, you may be left with a system that does not properly boot so it’s important to test first.

Summary

We have seen that it is possible to easily mount an NTFS disk in CentOS 7 Linux once the ntfs-3g package has been installed which provides us with the necessary drivers.

This did not work because the above is not a command but a line that should be inserted into /etc/fstab so that you can mount it automatically

[quote]
[root@Mustang /]# mount -t ntfs /dev/sdb2 /mymnt/win
mount: unknown filesystem type ‘ntfs’
[/quote]

This didn’t work because the filesystem type is not ‘ntfs’ but ‘ntfs-3g’ and, in any case, in order to have the system understand ntfs-3g you will need to have installed the ntfs-3g package from the EPEL repository.

unknown filesystem type ‘ntfs’

When mounting NTFS, you can encounter an error such as:

mount: /mnt: unknown filesystem type 'ntfs'

See #Explicit file system type required to mount.

If you want to use ntfs3 as the default driver for ntfs partitions, such udev rule does the trick:

/etc/udev/rules.d/ntfs3_by_default.rules

SUBSYSTEM=="block", ENV{ID_FS_TYPE}=="ntfs", ENV{ID_FS_TYPE}="ntfs3"

Although, this method is not recommended and can confuse some 3rd party tools.

udisks supports NTFS3, but has some issues at the moment. See udisks ntfs3 PR and issue 932.

Issues can manifest as the following errors, when the NTFS3 driver is used because NTFS-3G is not installed, but with mount options that it does not recognize:

ntfs3: Unknown parameter 'windows_names'

or

Filesystem type ntfs3,ntfs not configured in kernel

The second error in particular can be encountered with Dolphin.

As a workaround, add a such option to /etc/udisks2/mount_options.conf in [defaults] section:

ntfs_defaults=uid=$UID,gid=$GID,noatime,prealloc

See: Cannot mount NTFS with the new ntfs3 module from Linux 5.15

Unable to mount with ntfs3 with partition marked dirty

When trying to mount a good NTFS partition (i.e. which successfully mounts with NTFS-3G and for which ntfsfix --no-action does not report any error), you may get the following error:

mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.

ntfs3 will not mount a partition where the volume is marked dirty without the force option. dmesg explicitly helps recognizing the situation, saying:

sdb1: volume is dirty and "force" flag is not set!

You can try passing the --clear-dirty argument to ntfsfix to clean it. [1]

Linux mount U disk, reported this error:

mount: unknown filesystem type ‘ntfs’

This is due to that Linux cannot identify the disk partition with NTFS format.

Solution: by installing ntfs-3g to solve the problem.

1. download ntfs-3g installation package, directly through wget command, download to Linux system:

wget https://tuxera.com/opensource/ntfs-3g_ntfsprogs-2017.3.23.tgz

Note: you can also download in http://www.tuxera.com/community/ntfs-3g-download/, then copy to Linux.

2. unzip the package, then enter into the directory, compile and install ntfs-3g:

#./configure 
# make 
# make install 

Note: must install with root user.
 

3. execute the mount command, mount the U disk:

# mount –t ntfs-3g /dev/sdb1 /mnt/usb

Note: /dev/sdb1 is the U disk volume name, can be viewed through fdisk -l command, /mnt/usb is the destination directory to mount.

Now, it solves the problem that Linux system can not recognize NTFS format.

/dev/sdb1             128     2091135     1045504    7  HPFS/NTFS/exFAT

By default when I try to mount the NTFS disk, we get the below error.

[[email protected] ~]# mkdir /windows
[[email protected] ~]# mount /dev/sdb1 /windows/
mount: unknown filesystem type 'ntfs'

Install Required Packages

In order to perform the mount, we need to install the ntfs-3g package, which is a Linux NTFS userspace driver. This package comes from EPEL if you’re using CentOS/RHEL, so if you have not yet configured your system to use the EPEL repository, run the following command.

[[email protected] ~]# yum install epel-release -y

Now we should be able to install the ntfs-3g package from the EPEL repository.

[[email protected] ~]# yum install ntfs-3g -y

Otherwise if you’re using Ubuntu/Debian, you should just be able to run ‘apt-get install ntfs-3g’ straight away. In my Debian 8 installation it was already available so I was able to mount NTFS without any problems.

Mount The NTFS Disk

We can now successfully perform the mount without any errors.

[[email protected] ~]# mount /dev/sdb1 /windows/

[[email protected] ~]# blkid /dev/sdb1
/dev/sdb1: LABEL="NTFS" UUID="CA4A1FD94A1FC0DD" TYPE="ntfs"

We can confirm that the NTFS disk is now seen as mounted by the operating system.

[[email protected] ~]# df -h /windows/
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb1      1021M   11M 1011M   2% /windows

At this point you should be able to read and write data on the mounted NTFS disk.

Automatically Mount NTFS

We can create an entry in the /etc/fstab file so that our NTFS disk will automatically mount on system boot. Below is an example of the entry that I have placed into my fstab file. This will mount the disk to the /ntfs directory.

/dev/sdb1       /windows        ntfs-3g defaults        0 0

Once this configuration has been added, the NTFS disk should mount automatically on system boot. Before performing a reboot, it is recommended to first run the ‘mount -a’ command and confirm that the disk mounts without errors. If there are errors that happen during boot, you may be left with a system that does not properly boot so it’s important to test first.

Summary

We have seen that it is possible to easily mount an NTFS disk in CentOS 7 Linux once the ntfs-3g package has been installed which provides us with the necessary drivers.
