And how do you expect the mirrored iSCSI volume to work after
failover, with secondary (ex-primary) unreachable?

As a normal Degraded mirror. No problem. The suggestion was to make the SSD on each machine an iSCSI volume, and add the two volumes as a mirrored ZIL into the zpool.


It's a (relatively) simple and ingenious suggestion.

Is ISCSI reliable enough for this?

YES.

The original idea is a good one, and one that I'd not thought of.  The (old)
iSCSI implementation is quite mature, if not anywhere as nice
(feature/flexibility-wise) as the new COMSTAR stuff.

I'm thinking that just putting in a straight-through cable between the two
machine is the best idea here, rather than going through a switch.
