Report
It would seem that my oc_filecache_extended table has corrupted itself after a power outage. I’m only able to start mariadb with innodb_force_recovery = 2, and even then accessing this table causes the database to crash with signal 10.
Is it possible to rebuild/repair this table? I don’t know that I have a recent backup.
Is this the first time you’ve seen this error?: Y
Steps to replicate it:
- Lose power
- Turn things back on
- It broke

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

key_buffer_size=16384
read_buffer_size=262144
max_used_connections=2

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 52768 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
