Hi!
My guess is that you checked the corresponding logs already; why not show them
here?
I can imagine that the VMs die rather early after start.

Hi guys.
I quite often.. well, to frequently in my mind, see a VM
which cluster says:
-> $ pcs resource status | grep -v disabled
...
* c8kubermaster2 (ocf::heartbeat:VirtualDomain):
Started dzien
..
but that is false, also cluster itself confirms it:
-> $ pcs resource debug-monitor c8kubermaster2
crm_resource: Error performing operation: Not running
Operation force-check for c8kubermaster2
(ocf:heartbeat:VirtualDomain) returned: 'not running' (7)
What is the issue here, might be & how best to troubleshoot it?
-> $ pcs resource config c8kubermaster2
Resource: c8kubermaster2 (class=ocf provider=heartbeat
type=VirtualDomain)
Attributes:
config=/var/lib/pacemaker/conf.d/c8kubermaster2.xml
hypervisor=qemu:///system migration_transport=ssh
Meta Attrs: allow-migrate=true failure-timeout=30s
Operations: migrate_from interval=0s timeout=180s
(c8kubermaster2-migrate_from-interval-0s)
migrate_to interval=0s timeout=180s
(c8kubermaster2-migrate_to-interval-0s)
monitor interval=30s
(c8kubermaster2-monitor-interval-30s)
start interval=0s timeout=90s
(c8kubermaster2-start-interval-0s)
stop interval=0s timeout=90s
(c8kubermaster2-stop-interval-0s)
many thanks, L.

Not much there in the logs I could see (which is probably
why cluster decides the resource is okey)
What is the resource's monitor for it not for that exactly -
to check the state of resource - whether it dies early or
late should not matter.
What suffices in order to "fix" such resource
false-positive, I do quick dis/enable the resource or as in
this very instance rpm updates which restarted node.
Again, how cluster might think resource is okey while
debug-monitor shows it's not.
I only do not know how to reproduce this in a controlled,
orderly manner.
thanks, L
