All,
I have a problem that I can't find documentation on and has me baffled.
I have a 3 node cluster running xen with multiple domU enabled as
cluster services. The individual services are set to have a node
affinity using resource groups (see cluster.conf below) and live
migration is enabled.
I had migrated two domU off of one of the cluster nodes in
anticipation of a power-cycle and network reconfig. Before bringing
up the node that had been reconfigured I froze (clusvcadm -Z ...) the
domU in question so that when the newly reconfigured node came up they
would not migrate back to their preferred host, or at least that's
what I *THOUGHT* -Z would do.
I booted up reconfigured node, and ignoring their frozen state the
rgmanager on the rebooting node initiated a migration of the domUs.
The migration finished and the virtuals resumed operation on the
reconfigured host. The problem is now rgmanager is showing those
resrouce groups as having state "migrating" (even though there are no
migration processes still active) and clusvcadm -U ... returns the
following:
"Local machine unfreezing vm:SaturnE...Temporary failure; try again"
I get this message on all of the cluster nodes. I'm not sure if this
is coming from clusvcadm, vm.sh, or some other piece of the cluster
puzzle. Is there any way to get rgmanager to realize that these
resource groups are no longer migrating and as such can be unfrozen?
Is that even my problem? Can I fix this with anything other than a
complete power down of the cluster (disaster)?
