MySQL InnoDB disappeared, all InnoDB data cant be accessed
- by dogmatic69
Mysql (including InnoDB) was working fine, after a restart the other day when mysql starts it says in the logs:
140604 23:36:07 [Note] Plugin 'FEDERATED' is disabled.
140604 23:36:07 [Note] Plugin 'InnoDB' is disabled.
In the app it says:
SQLSTATE[42000]: Syntax error or access violation: 1286 Unknown storage engine 'InnoDB'
Now, according to google this is a very simple fix, just remove the ib_logfile[0|1] files, which I have done and does not do anything.
I started by making a full copy of the data dir for testing various 'fixes'.
I have also uninstalled mysql and reinstalled it with no change, I just cant get it to run with innodb working anymore :/
# mysql --version
mysql Ver 14.14 Distrib 5.5.37, for debian-linux-gnu (x86_64) using readline 6.3
I have also tried the innodb_force_recovery setting, 0 - 6, Any time I run a command on an InnoDB table it says innodb_force_recovery
LOGS (from around the time it died)
was working here
