I would appreciate it if someone could help point me in the direction of how to go about implementing this...
I'd like to have a HA iSCSI target comprised of two lightweight servers (the iSCSI targets, host A and host B) configured in failover which both are connected to a DAS device, like the Dell MD3000, so they have share drives. The DAS would likely be using raidz2. I've seen some past discussions that zfs does work in a clustered environment, but only in an active/passive mode, where only one device interacts with the DAS device at a time. This isn't a problem. It was mentioned that this was done with "HA Storage+", however I haven't really found any information on what HA Storage+ is. Secondly, I've seen that failover is possible with the iSCSI target when using Sun Cluster, but haven't found much info on actually using or setting it up in this way. Does it do multi-pathing, to where the end-client would need to discover both paths, or does it work by each server sharing a virtual IP, so when one fails, the other just picks up traffic on the IP? The other thing I'm curious about is if there would be any conflict between the failover of the iSCSI target and the active/passive file storage? I'm curious if there would potentially be a case where one hosts loses the connection with host A and then connects to host B, but then both are accessing the disks so it runs into issues. Has anyone tried to configure an HA iSCSI target in such a way before? Or maybe some advice on the best route to go to do an HA iSCSI target configuration? Thanks in advance!
