Hello all,
When I force a failover from one node to the other (I need all my resources on
the same node at all times) it might take a while for all resources to migrate.
One of the resources to migrate is the cluster IP but just because I can
connect to the other node (this resource has migrated) doesn't mean all of them
have.
I need a way to figure when the migration is complete. I could use crm_mon and
sleep/loop until all of them are on the other side (I know how many and what to
be looking for). For no good reason, I feel this is not very elegant. I think
I've heard about resource dependencies and how one can be declared to be
dependent on other(s). If this is true, can someone please point me to where I
can read about it? I'm thinking about defining a resource to be dependent on
all the others and verifying when this "phony" resource migrated which would
indicate they are all on the other side. Is this a good approach? Can you give
me any other idea for how to decide if the migration is over or not?
Thanks!
