[Pacemaker] Cluster goes to (unmanaged) Failed state when both nodes are rebooted together

[ihjaz Mohamed]

If I start the corosync together on both the servers, it comes up good. So am just wondering how is this different from corosync being started by the server during boot up.

Too bad, than you have to live with some limitations of this setup. You
could add some random wait to/before corosync start ... or simply: don't
reboot them at the same time ;-)

But it would also be interesting why FloatingIP_stop_0 returns an error
on both nodes ... logs should tell you what happened.

.... and remove nic="eth0:0", you must not define any alias here but
only the nic itself.

Regards,
Andreas
