Hi Ken,
Indeed the migration-threshold was the problem :-(
BTW, for a master-slave resource, is it possible to have different
migration-thresholds?
I.e. I'd like the slave to be restarted where it failed, but master to be
migrated to the
other node right away (by promoting the slave there).
I've tried configuring something like this:
[root@test-236 ~]# pcs resource show test-ha
Master: test-ha
Meta Attrs: master-node-max=1 clone-max=2 notify=true master-max=1
clone-node-max=1 requires=nothing migration-threshold=1
Resource: test (class=ocf provider=heartbeat type=test)
Meta Attrs: migration-threshold=INFINITY
Operations: start interval=0s on-fail=restart timeout=120s
(test-start-interval-0s)
monitor interval=10s on-fail=restart timeout=60s
(test-monitor-interval-10s)
monitor interval=11s on-fail=restart role=Master timeout=60s
(test-monitor-interval-11s)
promote interval=0s on-fail=restart timeout=60s
(test-promote-interval-0s)
demote interval=0s on-fail=stop timeout=60s
(test-demote-interval-0s)
stop interval=0s on-fail=block timeout=60s
(test-stop-interval-0s)
notify interval=0s timeout=60s (test-notify-interval-0s)
[root@test-236 ~]#
but It does not seem to help as both master and slave are always restarted
on the same node
due to test resource's migration-threshold set to INFINITY
Thank you in advance.
Regards,
Paolo
