Re: mysql not starting "[ERROR] Can't init tc log"

Are you actually running MySQL or is it MariaDB?

Have you tried this and this?

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: mysql not starting "[ERROR] Can't init tc log"

I just ran into this error, "Can't init tc log", running MariaDB.

mysql --version
mysql  Ver 15.1 Distrib 10.1.10-MariaDB, for Linux (x86_64) using readline 5.1

I ended up deleting the tc.log file in /var/lib/mysql. When I started mysql again, it created a new tc.log and started up.

Some background on my problem. I had let the partition with /var on it get full. After a reboot mysql wouldn't start, and tc.log was 0B. I cleared up some space but until I deleted tc.log, mysql wouldn't start.

This solution of deleting tc.log solved my problem on Debian 9 stable too.
Thank you very much!

Glad to hear, closing this 3 year old thread though.

Closing.
