I guess i shouldn't have used the "should" word :) I think the key fact here is that i am running the virtual machine on just one node and on top of DRBD, in any given moment. A concurrency scenario would happen if i'd have two virtual machines using the same virtual disk file, running each on it's node, and over DRBD set to primary/primary. Is this something that could really happen in case of mis-configuration of the cluster and/or lack of STONITH? tks, rodrigo > > Thanks, > > Dejan > _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
