Hi.
No. These are two different cases.
* When after kill lrmd resources don't start.
This http://send2me.ru/pcmk-Fri-21-Feb-2014.tar.bz2
* When standby a entrie cluster (all nodes standby).
Second node - hangs pending.
But last rebuild rpm - not confirmed the problem.
Therefore, this problem can be considered as long as not a problem.
