Hi,
Sorry about the missing info, here it is:
OS: CentOS 6.4
CoroSync: 1.4.1-15
Pacemaker: 1.1.10-1.el6-3463b39 (rc6)
Any more info needed to investigate this error?

Hi again!
I've played enough with corosync 2.3.x. nothing good yet.
Now I try build cluster with corosync/cman/pacemaker.
I started with http://clusterlabs.org/quickstart-redhat.html as saw Andrew.
More made my config in pacemaker (with stonith disabled).
The cluster started and I began tests
The stonith should be enabled, if you wanna your node joint the cluster in
clean state after you disconnect the cable.
Thanks

You need fencing. Specifically, cman blocks when a fence is called and
won't unblock until it's told that a fence completed successfully.
Configure cluster.conf to use 'fence_pcmk', which tells cman to pass
fence requests to pacemaker, and then configure (and test!) stonith in
pacemaker.

So I've switched my cluster to be asymmetric...
The remote nodes don't appear (although the VMs start, and pacemaker_remote
runs on them). This is a problem.
Temporarily switch to symmetric without restarting everything, and the
remote nodes appear in the cluster status. (But I'd have to do mor
Hello,
I am looking for different ways of testing that a node is down. I am
finding a strange behavior with one of them (closing with IPtables the UDP
communication port). I would like to know if closing the port is a
recommended way of achieving my testing purposes.
Also I would like to know oth
Hi Jacobo,
one very interesting thing is missing.
Overload the node. Make a programm/script which generates
many IO-operations, many flushes and meanwhile requesting
more and more memory from the OS until swapping begins.
Ohhh, yes, swapping and IO is nice…
…then you can prove your moni
