This is precisely the thing I did with poor results, except that I didn't have 4 nodes - I had only 2. So each node was both an initiator and a target. I made the initiator service dependent on the target service (so the initiator would go down first and come up second). I made zpool import of the iscsi pool dependent on the initiator being up, and I made vbox dependent on the iscsi zpool mounter. (see simplesmf, http://code.google.com/p/simplesmf/ for the zpool dependent on iscsi initiator) My word of advice, until such time (which may never come) that I might know more... Never, ever let the iscsi targets go down unless the initiators are both down first. _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
