[ClusterLabs] Pacemaker fails to start after few starts

[Kostiantyn Ponomarenko]

Hi Ken,

I remember with to be informed about this issue.
Unfortunately I cannot work on it right now, so it is postponed for some
time.
Anyway, as soon as I resume my work on it, I will let you know the result.
Thank you for the help and all the advises =)

P.S.: I noticed that "users at clusterlabs.org" wasn't in the later
conversation, so I am adding it to keep this info alive forever in the web
=)

Thank you,
Kostya
