It requires node-node=20 communication/membership/locking/master failover and hence a cluster=20 manager. I am nearing completion of the cluster manager currently, and= =20 then will work on the cluster services required to support md. I'll=20 post to this list once I have something working that I can open source. You cannot currently have two devices open on multiple nodes. It is=20 possible to use RAIDs in shared storage where each node only opens up=20 "its" assigned RAID devices. This can be enforced by RAID locking (see= =20 the list for a patch for this technique). I have a patch which locks=20 based upon geographical address/slot#, fibrechannel WWN, scsi host # bu= t=20 I have not had time to make this available and there wasn't a big=20 response when I posted the original patch.
