[Pacemaker] problem about move node from one clusterto another cluster

[Dan Frincu]

Hi,

Depending on the openais version (please mention it) this behavior could 
happen, I've seen it as well, on openais-0.8.0. What I've done to fix it 
was to restart the openais process via /etc/init.d/openais restart. And 
then it worked, however, this was one of the reasons I updated the 
packages to the latest versions of corosync, pacemaker, etc. The tricky 
part was doing the migration procedure for upgrading production servers 
without service downtime, but that's another story.

Regards,

Dan
