I've been running mariadb on a Pi zero for several weeks now with no problem. It's just for a couple pet projects. Small DBs and only couple relatively light queries per hour.
Server crashed few days ago and I've been seeing errors like the following below...
Cannot find checkpoint record at LSN (1,0x25b3)

I fixed this error by deleting all ARIA_log files and restarting mysqld*
My question is about why this randomly occurred and how to prevent it from happening again. Thanks!
