I have to said that the hard disk filled up and have to delete security log that went giant, but even after rebooting I have same error.

Thanks for your help

3 things to do:

1. Check available disk space df -h
2. Check available inodes df -i
3. Once they are cleaned up or has enough space remaining then reinstall mysql if the error persists yum reinstall mariadb

What OS are you using and did you restart the installation?
