1) During stop operation libvirt occasionally returns an error because the
state cannot be determined just the moment the machine is shut down. This
patch makes the RA try to get the state again one time. If the machine is
down then everything is OK.

That's default behaviour.
This only works if there's no helper module needed. So with the likes of

Hi
when the "ping" RA configured as
primitive ping ocf:pacemaker:ping timeout="5s"
it throws
[: 5s: integer expression expected
This patch fixes configurations where timeout is configured with a unit

Hi
I installed a new 3 node cluster today. I used the instructions on the
install page from the wiki and up to "corosync start" everything went
smooth.
At that point, apparently the following loop of corosync spawning
pacemaker and pacemaker crashing starts. See logs on

Hi Norbert
I don't know what you did in 11.2, but I'll try to tell you what I do.
I'm mostly still on 11.1 and use the clusterlabs repo. After installing

Just for the record: heartbeat (3.0.2) was not able to recover either.
It also manages to see a failure on the dead node but fails to recover.

Both work, in fact crm uses cibadmin in the background for some commands.
crm uses readable, easier to remember syntax and commands, whereas
cibadmin needs xml input (at least most of the time).
So it's basically a question of preference.

So here's an update. Michael Schwartzkopf pointed out a bug regarding

There's not been a lot of feedback, is it because nobody uses the script

just using Dummy resource, but that doesnt matter) to replace a system

Hi
I made the necessary changes to the showscores script to work with
pacemaker 1.0.2.
Please test and report problems. Has been reported to work by some
people and should go into the repository soon. Still, I'd like more
people to test and confirm.
Important changes:
* correctly fetch stickines
.
This is because the RA stops pingd with kill -9, which does not let it
execute the normal pingd shutdown procedure (which includes setting the
attribute to 0).
Patch is attached.
