HA cluster fail over left mysql services still running on slave

We had a cluster fail over happen, but it wasn’t a clean fail over.
Some service are now running on freepbx-b,others still on freepbx-a (drbd_spare, drbd_mysql).
Don’t know why the fail over happened and why mysql is still running on secondary node. Anything wrong with mysql?
What action to take now? Bring individual services, like mysql over to freepbx-b, or put the whole node into standby?

That is actually how it’s supposed to work, if your Asterisk service was not able to be restarted it will fail that over to the other node and leave mysql running on the first node. I believe this allows you to fail-over quicker. If you want to move services back you would manage your node as outlined here: http://wiki.freepbx.org/display/FPG/FreePBX+HA-Managing+Nodes
