I don't know how to diagnose this.
Until yesterday, when we had a power interruption, ZM was working perfectly fine in Unraid under a Docker container.
After rebooting, I'm getting the following:
Starting services...
* Starting Apache httpd web server apache2
*
* Stopping MariaDB database server mysqld
...done.
* Starting MariaDB database server mysqld
...fail!
DBI connect('database=zm;host=localhost','zmuser',...) failed: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) at /usr/share/perl5/ZoneMinder/Database.pm line 110.
I don't know how to diagnose this error as the Docker container won't start, so I can't CLI into it to test anything.
What now?
