[ClusterLabs] Pacemaker quorum behavior

Hi folks..

I have some follow-up questions about corosync daemon status after cluster
shutdown.

Basically, what should happen to corosync on a cluster node when pacemaker
is shutdown on that node?
On my 5 node cluster, when I do a global shutdown, the pacemaker processes
exit, but corosync processes remain active.

Here's an example of where this led me into some trouble...

My cluster is still configured to use the "symmetric" resource
distribution.   I don't have any location constraints in place, so
pacemaker tries to evenly distribute resources across all Online nodes.

With one cluster node (KVM host) powered off, I did the global cluster
stop:

[root at zs90KP VD]# date;pcs cluster stop --all
Wed Sep 28 15:07:40 EDT 2016
zs93KLpcs1: Unable to connect to zs93KLpcs1 ([Errno 113] No route to host)
zs90kppcs1: Stopping Cluster (pacemaker)...
zs95KLpcs1: Stopping Cluster (pacemaker)...
zs95kjpcs1: Stopping Cluster (pacemaker)...
zs93kjpcs1: Stopping Cluster (pacemaker)...
Error: unable to stop all nodes
zs93KLpcs1: Unable to connect to zs93KLpcs1 ([Errno 113] No route to host)

Note:  The "No route to host" messages are expected because that node /
LPAR is powered down.

(I don't show it here, but the corosync daemon is still running on the 4
active nodes. I do show it later).

I then powered on the one zs93KLpcs1 LPAR,  so in theory I should not have
quorum when it comes up and activates
pacemaker, which is enabled to autostart at boot time on all 5 cluster
nodes.  At this point, only 1 out of 5
nodes should be Online to the cluster, and therefore ... no quorum.

I login to zs93KLpcs1, and pcs status shows those 4 nodes as 'pending'
Online, and "partition with quorum":

Here you can see that corosync is up on all 5 nodes:

[root at zs95kj VD]# date;for host in zs90kppcs1 zs95KLpcs1 zs95kjpcs1
zs93kjpcs1 zs93KLpcs1 ; do ssh $host "hostname;ps -ef |grep corosync |grep

But, pacemaker is only running on the one, online node:

[root at zs95kj VD]# date;for host in zs90kppcs1 zs95KLpcs1 zs95kjpcs1
zs93kjpcs1 zs93KLpcs1 ; do ssh $host "hostname;ps -ef |grep pacemakerd |

You have new mail in /var/spool/mail/root
[root at zs95kj VD]#


This situation wreaks havoc on my VirtualDomain resources, as the majority
of them are in FAILED or Stopped state, and to my
surprise... many of them show as Started:

Pacemaker is attempting to activate all VirtualDomain resources on the one
cluster node.

So back to my original question... what should happen when I do a cluster
stop?
If it should be deactivating, what would prevent this?

Also,  I have tried simulating a failed cluster node (to trigger a STONITH
action) by killing the
corosync daemon on one node, but all that does is respawn the daemon ...
causing a temporary / transient
failure condition, and no fence takes place.   Is there a way to kill
corosync in such a way
that it stays down?   Is there a best practice for STONITH testing?

As usual, thanks in advance for your advice.

In my experience, this is sufficient to say that pacemaker and corosync
aren't running.

Your expectation is correct; I'm not sure what happened in this case.
There are some obscure corosync options (e.g. last_man_standing,
allow_downscale) that could theoretically lead to this, but I don't get
the impression you're using anything unusual.

FYI the Online/Offline above refers only to pcsd, which doesn't have any
effect on the cluster itself -- just the ability to run pcs commands.

"pending" means that the node has joined the corosync cluster (which
allows it to contribute to quorum), but it has not yet completed the
pacemaker join process (basically a handshake with the DC).

I think the corosync and pacemaker detail logs would be essential to
figuring out what's going on. Check the logs on the "pending" nodes to
see whether corosync somehow started up by this point, and check the
logs on this node to see what the most recent references to the pending
nodes were.
