Hi, all
I configured crmd-transition-delay="2s" to address the following problem.
http://www.gossamer-threads.com/lists/linuxha/pacemaker/68504
http://developerbugs.linux-foundation.org/show_bug.cgi?id=2528
And then, "crm resource restart" command get become less able to
restart any resources on the DC node.
# "crm resource restart" works fine on the non-DC node.
# Please see attached hb_report generated on the simple environment.
How can I use "crm resource restart" command on the DC node
with crmd-transtion-delay="2s"?
Sounds like the shell isn't waiting long enough.
I understood that it is hard to resolve this problem by the
configuration and we need to fix crm shell. Would that be about right?
If so, I made a patch for crm shell that wait a crmd-transition-delay
before checking DC node status.
Please see attached patch.
Best regards,
I confirmed that I can avoid this problem by the following procedure
1. "crm resource stop rsc-ID"
2. wait crmd-transtion-delay(2) scond
3. "crm resource start rsc-ID"
but this behavior(restart does not works on the DC node)
may be confuse users.
Best regards,
