So it looks like all of the database tables were corrupt. This could explain a few things.
I've run repairs on all of them except for 'zimbra_logger.raw_logs' which is still running (been a few hours). It's a 4GB table so I'll give it a little while longer.
The other table I'm having problems with is 'zimbra_logger.mta'. Here is the output I'm getting.
Code:
mysql> check table mta;
+-------------------+-------+----------+-------------------------------------------------------------------+
| Table | Op | Msg_type | Msg_text |
+-------------------+-------+----------+-------------------------------------------------------------------+
| zimbra_logger.mta | check | error | Table upgrade required. Please do "REPAIR TABLE `mta`" to fix it! |
+-------------------+-------+----------+-------------------------------------------------------------------+
1 row in set (0.00 sec)
mysql> REPAIR TABLE `mta`;
+-------------------+--------+----------+--------------------------------------------------------------------------------------+
| Table | Op | Msg_type | Msg_text |
+-------------------+--------+----------+--------------------------------------------------------------------------------------+
| zimbra_logger.mta | repair | Error | Table './zimbra_logger/mta' is marked as crashed and last (automatic?) repair failed |
| zimbra_logger.mta | repair | Error | Table 'mta' is marked as crashed and last (automatic?) repair failed |
| zimbra_logger.mta | repair | status | Table is already up to date |
