Hi All,
pacemaker has one property "on_fail" for any operation configured
for a resource. suppose i have set "on_fail" to "fence" for a
monitor operation , then is it expected to fence the node in case of
resource monitor failure ??
that would seem like a reasonable assumption
Thanks Andrew for fast reply,
i assume we need stonith for this.
definitely
when resource monitor will fail on a node it means that node is
undergoing some problematic situation , and due to this the
resource fails over to another node.
Well , now i am wondering if a node is not well then stonith will
already come into the action.
if stonith is enabled (the default in 1.0.0 and onwards), then it
kicks in whenever a node fails or a resource fails to stop.
i mean to say even if i will not set "on_fail" to fence the node
will be fenced by stonith (as other members of cluster will detect
that node is not doing well and they will fence that errant node)
so why do we have this "on_fail" feature. is there any special
benefit of this "on_fail" feature i am missing??
setting on_fail=fence for a monitor op will cause the cluster to shoot
the node immediately instead of trying to stop the resource and
recover it without fencing.
can any one explain please.
Best Regards,
