Re: [Linux-cluster] disk fencing



I'm not sure what you're asking here, but it sounds like you're describing a qdisk.

If a node loses heartbeat with the rest of the cluster, that's a fencin'. Doesn't matter if it can still access the shared storage, and if it has lost communication with the rest of the cluster, you probably don't want it accessing your data anyway.

Has anybody looked into using the network for heartbeat only, and disk
for fencing in GFS?  i.e. using the disk to communicate quorum when
network heartbeat is lost between 1 or more nodes.  If the disk is
still accessible to all nodes, this should be a valid way to
communicate quorum, if not, then the remaining nodes, assuming enough
for quorum, should be able to continue knowing that nodes it can't
communicate with either have been fenced or can't read/write to disk
anyway.  Does this sound like a valid approach?
