Re: [Koha] Sessions table corrupt in Koha 3.0
Edward, Drop the table then recreate it. Your users will have to log in again, but that's it. I'm not sure that will reclaim the disk space, though.

Re: [Koha] Sessions table corrupt in Koha 3.0
The sessions table tracks logins to the system, and can drastically slow your system down if it gets too large. You can safely truncate it entirely; doing so will disconnect anyone presently logged in but it sounds like you can’t log in at the moment anyway. There is a script (misc/cronjobs/cleanup_database.pl) which has an option to clear the table overnight as a cron job, to keep it from getting too big.

Re: [Koha] Sessions table corrupt in Koha 3.0
Thanks Jared. This is probably my solution, however, I can't seem to drop this table. This is probably a basic mysql question, but how can I force a drop or remove a lock? When I try to drop the table, it just sits there waiting for the table: mysql> show processlist; ++---+---+--+-+--+---+-+ | Id | User | Host | db | Command | Time | State | Info | ++---+---+--+-+--+---+-+ | 7 | kohaadmin | localhost | koha | Query | 31 | Waiting for table | drop table sessions | | 8 | kohaadmin | localhost | koha | Query | 0 | NULL | show processlist | ++---+---+--+-+--+---+-+ 2 rows in set (0.00 sec) mysql> IS there a way to "force the drop" or unlock the table?

Okay, I got this part fixed. I managed to drop the table by starting mysql using mysqld_safe. Still need to create the table though, hopefully that will work.

A little late of an update, but for the archives, dropping and then recreating the table fixed the problem. Edward -- Edward M.

Re: [Koha] Sessions table corrupt in Koha 3.0
Truncating should work fine, but I saw somewhere (I think in the e-mail archives not positive), that it could take longer. I'm not sure that is true or not since I didn't try it. The advantage to truncate though would be I wouldn't have had to look up how to recreate the table.

It's possible that was unnecessary, but given that the problems all started when the system ran out of disk space, it seemed like a worthwhile precaution.
