I am working on a project where i need to create a database with 300 tables for each user who wants to see the demo application. it was working fine but today when i was testing with a new user to see a demo it showed me this error message
1030 Got error 28 from storage engine
After spending some time googling i found it is an error that is related to space of database or temporary files. I tried to fix it but i failed. now i am not even able to start mysql. How can i fix this and i would also like to increase the size to maximum so that i won’t face the same issue again and again.

Mysql error «28 from storage engine» — means «not enough disk space«.
To show disc space use command below.
myServer# df -h
Results must be like this.
Filesystem Size Used Avail Capacity Mounted on
/dev/vdisk 13G 13G 46M 100% /
devfs 1.0k 1.0k 0B 100% /dev

To expand on this (even though it is an older question); It is not not about the MySQL space itself probably, but about space in general, assuming for tmp files or something like that.
My mysql data dir was not full, the / (root) partition was

I had the same issue in AWS RDS. It was due to the Freeable Space (Hard Drive Storage Space) was Full. You need to increase your space, or remove some data.

My /tmp was %100. After removing all files and restarting mysql everything worked fine.

My /var/log/apache2 folder was 35g and some logs in /var/log totaled to be the other 5g of my 40g hard drive. I cleared out all the *.gz logs and after making sure the other logs werent going to do bad things if I messed with them, i just cleared them too.
echo "clear" > access.log
etc.

Check your /backup to see if you can delete an older not needed backup.

I had a similar issue, because of my replication binary logs.
If this is the case, just create a cronjob to run this query every day:
PURGE BINARY LOGS BEFORE DATE_SUB( NOW(), INTERVAL 2 DAY );
This will remove all binary logs older than 2 days.
I found this solution here.

A simple:
$sth->finish();
Would probably save you from worrying about this. Mysql uses the system’s tmp space instead of it’s own space.

sudo su
cd /var/log/mysql
and lastly type: > mysql-slow.log
This worked for me

Drop the problem database, then reboot mysql service (sudo service mysql restart, for example).

If you want to use the tokudb plugin
This can happen if you have less than 5% (by default) of free space.
see the option: tokudb_fs_reserve_percent

Introduction
In this article, you have how to resolve Mysql 1030 got error 28 from storage engine.
If you have any experience hosting MySQL systems, you have most likely run into the following error at some point. The following are some suggestions for how to correct it.
Error 28 is a message that frequently appears when you use MySQL as your storage engine. This message indicates that the drive is full, which means that one or more of the partitions on your server have run out of space, and MySQL is unable to write to the disc as a result. In order for MySQL to run, you will need to free up space on your disc.
It’s possible that the query you ran caused MySQL to generate some temporary tables. In the default configuration, these tables will be created along with the other tables. This means that they will most likely be stored on your / partition, which only has 1.6 GB of free space remaining, despite the fact that these tables have the potential to grow much larger than that very quickly.
Solution 1.
Insufficient disc space is the cause of MySQL error «28 from storage engine.»
Use the following command to display available disc space.
#df -h
This is how the results must be.
Solution 2.
The amount of available storage space must be increased, or unnecessary files must be deleted.
Solution 3.
Remove Items from the Temporary Directories
Switch to the /var/tmp folder.
#cd /var/tmp
Deleting everything in the current directory and its subfolders.
#rm -rf *
Or you can remove the files that are not useful to you, by the command:
#rm -rf filename
Solution 4.
Explore the contents of /backup to discover if an unnecessary backup may be removed.
conclusion
Hopefully, you now understand how to resolve Mysql 1030 got error 28 from storage engine.
Thank You 🙂

Basically MySQL is giving me many errors of «Got error 28 from storage engine» that means no more disk space is available.
The output of df -h is:
File system Dim. Usati Disp. Uso% Montato su
/dev/md1 10G 7,9G 1,6G 84% /
tmpfs 2,0G 0 2,0G 0% /lib/init/rw
udev 10M 176K 9,9M 2% /dev
tmpfs 2,0G 0 2,0G 0% /dev/shm
/dev/md2 683G 601G 48G 93% /home
Every filesystem here is not empty. Are there any other problem?
I am on
— a dedicated server (debian 64bit )
— and the errors happens doing an heavy query

It might be that your query makes MySQL create temporary tables. In the default configuration, these will be created alongside the other tables, which is likely on your / partition which has only 1.6GB left, and these tables can become larget than that really quickly.
Watch your free space while you do such a query.
See this documentation about it.

Two other possibilities:
- Filesystems often reserve 5% of the space and return an error when it reaches 95% full. Your
/homeis at 93%. - You get the same error message when you run out of inodes, even if you still have disk space left. You can see inodes with
df -i.
I think SvenW’s answer is more likely to be correct. His reasoning is sound and I have run into exactly the same issue myself.
You can figure out whether the query is going to use a temporary table by running EXPLAIN <query> in your MySQL instance, replacing <query> with the actual query. You are looking for «Using temporary» in the Extra section. Temporary tables will be written to disk if they are larger than max_heap_table_size and/or tmp_table_size in your my.cnf.
You can find what directory MySQL is using for temporary tables by looking at the tmpdir variable either in the running instance (mysql> SHOW VARIABLES LIKE 'tmpdir';) or in your my.cnf (grep tmpdir my.cnf).
