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.
I am thinking more that if server A has the ip address 1.2.3.4 and
server B has 1.2.3.5
if server A breaks server B takes over 1.2.3.4 along with 1.2.3.5.
Another scenario would be that either server A or B has 1.2.3.4 and if
running server dies the other server takes over the address.
