What I observe is that single monitoring request of different
resources with different resource agents is timing out.
For example LVM resource (the LVM RA) does this sometimes.
Setting ridiculously high timeouts (5 minutes and more) didn't solve
the problem, so I think I'm out of options there.
Same for other I/O related resources/RAs.
hmm, so probably is something bad in clvm configuration? I use clvm in
three node cluster without issues. Which version of centos u use? I
experience clvm problems only on pre 7.3 version due to bug in libqb.
I have timeouts with and without clvm. Have it with resources managing
(scst) iscsi targets as well.

One of the typical cases is LVM (LVM RA)monitoring.

Hi Ulrich,
Have to disagree here.
I have cases, when for an unknown reason a single monitoring request
never returns result.
So having bigger timeouts doesn't resolve this problem.
But if your monitor hangs instead of giving a result, you also
cannot ignore
the result that isn't there! OTOH: Isn't the operation timeout for
monitors
that hang? If the monitor is killed, it returns an implicit status (it
failed).
I agree. It seems to me the problems comes from either the resource
agent or
the resource itself. Presently, this issue bothers the cluster
stack, but soon
or later, it will blows something else. Track where the issue comes
from, and
fix it.
