I am trying to;

 

Run mysql on a two node cluster (active/active) with circular
replication enabled <- I have already set this setup

 

Run two virtual IPs, one on each node when both nodes are healthy and
mysql is running <- also apready running

 

Move the IP from the failed node to the good node if the node fails
(easy enough) or if mysql fails <- my challenge

 

How can I create a constraint that says;

 

Run this ip resource on this node if mysql is running, but move it to
the other node if it is not?  So that the IP prefers one node only if my
sql is running ,but will gotohe other node if it is not.

 

I am currently using the lsb RA to monitor both instances of mysql (on
resource on each node)

 

Does the ofc RA support active active mysql and is there a way to move
the Ip as desired?

 

Thanks
