[Pacemaker] Antwort: Re: sles11, ocfs2, 2 node cluster with one storage, failover problem

[Patrik.Rapposch at knapp.com]

hy,

thx guys, for the help, to my regret the ocfs2 project  was put on ice and
I am right now working on the clvm solution, so it will be no more possible
to test something with ocfs2 in the near future.

but I hope that it will better work with sp1, which released these days.

Mit freundlichen Grüßen / Best Regards

      openais/pacemaker can't handle ifdown. Neither can corosync with
      multiple rings. You have to make sure that the interface stays up
      at all times (i.e. don't use dhcp).
