Hi there,
In this 3 node cluster, node03 been offline for a while, and being
brought up to service. Then a migration of a VirtualDomain is being
attempted, and node02 is then fenced.
Provided is logs from all 2 nodes, and the 'pcs config' as well as a
bzcatted pe-warn. Anyone with an idea of why the node was fenced ? Is
it because of the failed ipmi monitor warning ?
After a short glace it looks as if the network traffic used for VM
migration
killed the corosync (or other) communication.
May I ask what part is making you think so ?
The part that I saw no reason for an intended fencing.
And it looks like node02 is being cut off from all
networking-communication - both corosync & ipmi.
May really be the networking-load although I would
rather bet on something more systematic like a
Mac/IP-conflict with the VM or something.
I see you are having libvirtd under cluster-control.
Maybe bringing up the network-topology destroys the
connection between the nodes.
Has the cluster been working with the 3 nodes before?
Klaus
Here is the outline:
At 06:58:27 node03 is being activated with 'pcs start node03', nothing
suspicious in the logs
At 06:59:17 a resource migration is attempted from node02 to node03
with 'pcs resource move sikkermail30 kvm03-node02.logiva-gcs.dk'
on node01 this happens:
Apr 15 06:59:17 kvm03-node01 pengine[29024]: warning: Processing
failed monitor of ipmi-fencing-node01 on kvm03-node02.logiva-gcs.dk:
unknown error
And node02 is fenced ?
