Dear List Users,
I have mediawiki 1.29-Release running on FreeBSD-11.1-Release and have had
a crash of my MySQL database. At first, I couldn't start it at all. But
after deleting ib_logfile* and ibdata*, it came back alive. In the sense
that I can start the server and use many of the databases. But not the one
holding my mediawiki installation.
The error log says
"[Warning] InnoDB: InnoDB: Cannot open table mediawiki_something_dk/user
from the
internal data dictionary of InnoDB though the .frm file for the table
exists.."
The debug log is quite full but has the message
"Error: 1146 Table 'mediawiki_something_dk.l10n_cache' doesn't exist
(localhost)"
Does anyone know how to solve this? Or maybe have somehere, I can look for
a solution.
I'm not sure what sort of solution you're looking for. You deleted the
InnoDB data file (ibdata*), and now it unsurprisingly says the InnoDB
data file is gone. That file had your wiki in it, now it's gone.
If you have backups, we can talk about how to recover from them.
Otherwise, DROP DATABASE mediawiki_something_dk; might possibly wipe
those .frm files and put the database back into a consistent (empty)
state. Not sure, I've never heard of anyone deleting ibdata file
before. If it does work, then you can make a new empty wiki, if that
is a useful thing for you.

It's a bit late for that, he's literally deleted his entire wiki.
