Hi, I'm having a two-node Corosync/Pacemaker cluster (active/passive) with XFS on two DRBD-volumes (SLES11 SP1 + HAE). The active node has both volumes mounted and if this node fails, the passive node should take over and mount these volumes. I'm aware that I can't mount XFS simultaneously on both nodes (which is not a problem).
The setup runs fine so far, with both DRBD-volumes in dual-primary mode (and STONITH configured). But I'm currently not sure, if the dual-primary mode is actually needed or if there's a way to run in safer primary/secondary mode. I think, in an earlier stage of this cluster and the disks being configured as primary/secondary, I've had problems to get the secondary disk promoted to primary after the old primary failed (i.e. was shut off). I remember a "refusing to be primary while peer is not outdated" message in that case, but that may have had other causes. What's the best/safest approach in my case? -- Sebastian Kaps _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
