Hi All

We are trying to High Availability solution for our database. We have
our application running on a node-1 and the DB running on the shared
storage which is shared across node-1 & node-2. Whenever there is a
power Failure on node-1 , we start our application on node-2 but our
problem is that now after a failover onto node-2 the DB deamon on node-2
will fail to start.

Mysql version information:

On the node-2 when the DB deamon tries to start we are seeing the
following error messages in the log file:
