<div>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.</div>

I have timeouts with and without clvm. Have it with resources
managing (scst) iscsi targets as well.<br>

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

I have cases, when for an unknown reason a single

So having bigger timeouts doesn't resolve this

But if your monitor hangs instead of giving a result,
you also cannot ignore<br class="">
the result that isn't there! OTOH: Isn't the operation
timeout for monitors<br class="">
that hang? If the monitor is killed, it returns an
implicit status (it<br class="">
failed).<br class="">

I agree. It seems to me the problems comes from either
the resource agent or<br class="">
the resource itself. Presently, this issue bothers the
cluster stack, but soon<br class="">
or later, it will blows something else. Track where the
issue comes from, and<br class="">
fix it.<br class="">
