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.
This question is related to
mysql
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.
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.
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
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.
Drop the problem database, then reboot mysql service (sudo service mysql restart, for example).
My /tmp was %100. After removing all files and restarting mysql everything worked fine.
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.
sudo su
cd /var/log/mysql
and lastly type: > mysql-slow.log
This worked for me
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
