[Pacemaker] Exec Failure issues.

[James Horsfall (CTR)]

The allow-migrate was just something I was trying, and as you point out
produced that error unimplemented feature. Without the allow-migrate
option I just get "exec timeout error" which is doubly as frustrating,
where its simply failing to unload the ip addresses from the failed
node. It knows it's supposed to migrate, it starts to and then goes nuts
into the error timeout "unmanaged" state. At that point I have to
essentially restart the nodes to clear the error or clear the fail
counts from the "IPS" element just to watch it explode all over again.

 The setup of stonith seems extreme by its description. Will this
properly bring nodes back online after cables are re-plugged? I'm not
sharing data I'm just setting up a network pass through server or just a
router in a sense.


Thanks for the input

ETH2_stop_0 (node=sgn-pau-hub0, call=12, rc=3, status=complete):
unimplemented feature

That's a failed stop with fencing disabled. That's always going to
freeze the cluster. Set up STONITH.

And the reason it's failing is that, at the risk of stating the obvious,
you're trying to invoke a feature that is not implemented in IPaddr2:

primitive ETH2 ocf:heartbeat:IPaddr2 \
	meta allow-migrate="true" is-managed="true"

Who or what prompted you to set the "allow-migrate" meta attribute here?
