InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

Hi, I would recommend using a competent system admin help to fix it.
So, if you understand what exactly you doing you try to fix it with the command below:

Code: [Select]

cd /var/lib/mysql/
mv ib_logfile0 ib_logfile0_OLD
mv ib_logfile1 ib_logfile1_OLD
systemctl restart mariadb
If MariaDB has been started then use the command below:

Code: [Select]

mysql_upgradeif MariaDB has not been started the you have to ask a sysadmin to check that.

i am getting this message

[root@vps ~]# cd /var/lib/mysql/
[root@vps mysql]# mv ib_logfile0 ib_logfile0_OLD
mv: cannot stat ‘ib_logfile0’: No such file or directory
[root@vps mysql]# mv ib_logfile1 ib_logfile1_OLD
mv: cannot stat ‘ib_logfile1’: No such file or directory
[root@vps mysql]# systemctl restart mariadb
