AFAIR pacemaker tries to migrate all at once (which is not the best idea performance-wise), but you can limit the number of concurrent migrations…


-1 (unlimited)

The number of migration jobs that the cluster is allowed to execute in parallel on a node.

Hi guys.

When it's done by the cluster itself, eg. a node goes 'standby' - how do clusters migrate VirtualDomain resources?
Do users have any control over it and if so then how?
I'd imagine there must be some docs - I failed to find
Especially in large deployments one obvious question would be - I'm guessing as my setup is rather SOHO - can VMs migrate in sequence or it is(always?) a kind of 'swarm' migration?

many thanks, L.
