Hi folks,

I'm assigned to system test Pacemaker/Corosync on the KVM on System Z
platform
with pacemaker-1.1.13-10 and corosync-2.3.4-7 .

I have a cluster with 5 KVM hosts, and a total of 200
ocf:pacemakerVirtualDomain resources defined to run
across the 5 cluster nodes (symmertical is true for this cluster).

The heartbeat network is communicating over vlan1293, which is hung off a
network device, 0230 .

In general, pacemaker does a good job of distributing my virtual guest
resources evenly across the hypervisors
in the cluster. These resource are a mixed bag:

- "opaque" and remote "guest nodes" managed by the cluster.
- allow-migrate=false and allow-migrate=true
- qcow2 (file based) guests and LUN based guests
- Sles and Ubuntu OS

Stack: corosync

103 nodes and 300 resources configured

Online: [ zs93KLpcs1 zs93kjpcs1 zs95KLpcs1 zs95kjpcs1 ]

This morning, our system admin team performed a
"non-disruptive" (concurrent) microcode code load on the OSA, which
(to our surprise) dropped the network connection for 13 seconds on the S93
CEC, from 11:18:34am to 11:18:47am , to be exact.
This temporary outage caused the two cluster nodes on S93 (zs93kjpcs1 and
zs93KLpcs1) to drop out of the cluster,
as expected.

However, pacemaker didn't handle this too well. The end result was numerous
VirtualDomain resources in FAILED state:

zs95kjg109106_res (ocf::heartbeat:VirtualDomain): FAILED zs93kjpcs1

As well as, several VirtualDomain resources showing "Started" on two
cluster nodes:

zs95kjg110079_res (ocf::heartbeat:VirtualDomain): Started[ zs93kjpcs1
zs93KLpcs1 ]
zs95kjg110108_res (ocf::heartbeat:VirtualDomain): Started[ zs93kjpcs1
zs93KLpcs1 ]
zs95kjg110186_res (ocf::heartbeat:VirtualDomain): Started[ zs93kjpcs1
zs93KLpcs1 ]
zs95kjg110188_res (ocf::heartbeat:VirtualDomain): Started[ zs93kjpcs1
zs93KLpcs1 ]
zs95kjg110198_res (ocf::heartbeat:VirtualDomain): Started[ zs93kjpcs1
zs93KLpcs1 ]

The virtual machines themselves were in fact, "running" on both hosts. For
example:

[root at zs93kl ~]# virsh list |grep zs95kjg110079
70 zs95kjg110079 running

[root at zs93kj cli]# virsh list |grep zs95kjg110079
18 zs95kjg110079 running

On this particular VM, here was file corruption of this file-based qcow2
guest's image, such that you could not ping or ssh,
and if you open a virsh console, you get "initramfs" prompt.

To recover, we had to mount the volume on another VM and then run fsck to
recover it.

I walked through the system log on the two S93 hosts to see how
zs95kjg110079 ended up running
on two cluster nodes. (some entries were omitted, I saved logs for future
reference):

===================

Does this "active on two nodes" recovery process look right?

What is the recommended procedure to "undo" the resource failures and dual
host assignments? It took several hours (short of stopping/starting the
entire cluster)
to recover them... resource disable, cleanup, enable was the basis ... but
it seemed that I would fix one resource and two more would fall out.

This seems to be one of the pitfalls of configuring resources in
symmetrical mode.

I would appreciate any best practice guidelines you have to offer. I saved
the system logs on all hosts in case anyone needs more detailed
information.
I also have pacemaker.log logs.

Thanks in advance!
