I'm trying to set up an active/passive failover for MySQL and have a
problem with getting cluster suite to start mysql. It just keeps
telling me to 'look in the logs' for a problem that isn't there.
The main issue seems to be that it decides that MySQL has failed and
I can't 'disable' it to 'enable' it. The disable command fails 'cause
MySQL isn't actually running anymore.

The only way I can get past this is manually mount the database file
system, manually create the IP address and start MySQL manually - then
tell the cluster manager to disable MySQL. Only even then it gets in a
wierd state and one let me re-enable MySQL again - only this time it
doesn't write anything useful in the logs.
Any one have any pointers ?. I'm not trying to load balance or
anything, just having a standby machine to take over if the first fails.
