[Ocfs2-users] Mounting multiple ocfs2-volumes and disk heartbeat
Hi, at the moment we run a two node cluster on SLES10 SP2 and OCFS2 1.4 with a Sun StorageTek 2540FC as shared disk. For performance reasons we plan to add a second storage device. As we only use the first FC-port of each node, we thought we can use the second FC-port (of each node) to connect to the additional storage. Now two question came up: 1. is this a reasonable configuration? 2. where does the disk heartbeat go to (to first device or to second device)? Thanks, Gerd _______________________________________________ Gerd Pickel Systemadministration BETAX-systems GmbH _______________________________________________

Sure. The default o2cb heartbeat is tied to the mounts. So in your case it will hb on both paths.
