Subject: What happens if an iSCSI target resets.
I am thinking of a 2 node cluster that sync the disks via DRBD.
I have seen some articles about using multipath and 2 independent
targets but have also seen generic problem descriptions of using
multipath in the face of failures.
I was thinking of using a floating IP address for the target and using
the clustering/HA glue to make it move between servers.
When you say floating IP's does that mean they will not be static? That
might not work very well with open-iscsi. If we lose the connection or
run the error recovery and have to relogin we will try to use the IP
that we started with.
Some targets like from Equallogic will have a static IP that the
initiator logs into, then the target will tell us about a different IP
to use. We then login there and do IO. If we get disconnected though, we
go back the first IP and it redirects us again.
