[ClusterLabs] Resource getting hard-flipped when node recovers

[Matthew Vernon]

Hi,

I have a 3-node pacemaker/corosync cluster (output of crm configure save
below); my resource is a xen guest, and if I make its live node standby,
then it is live-migrated, as you'd expect.

If I hard-power-off the live node, then the other xenhost node starts up
the guest, as you'd expect.

When, however, I turn the formerly-live node back on, the guest is
stopped on the newer-live node, and started on the formerly-live node again.

I don't mind this moving, but I do mind that it's a stop-and-start
rather than a migration. Can I stop this happening?

Thanks,

Matthew
