Well, I can tell you what I think: WOOOOOOHHHHHHOOOOOOOOOOOOOOOOOOO!!!
I haven't had time to read that entire discussion yet (gotta take the baby & the dog out for a walk), but I can't tell you guys how happy I am to see this. I'm desperate to use ZFS over iSCSI to mirror a couple of servers, but it was an unworkable solution with a 3 minute timeout. Being able to tweak that down to a 1-2 second timeout would be great. Funnily enough, exactly the opposite situation to yours; I want it far less tolerant than the default. Could I ask you to please touch base with the iSER guys (Peter Dunlap, David Hollister & Jesse Butler) since I was e-mailing them only last week to find out whether this had been addressed in their code. At the time it hadn't since it's based on the standard iSCSI code, but if that means these parameters can be integrated there too it would be perfect. For me, what needs tweaking is whatever parameters define the timeout period when a cable is disconnected, since ZFS hangs the whole pool for 3 minutes waiting for a reply if an iSCSI device goes offline. I believe that's line 227 of iscsi.h, but I'm not 100% sure: http://bugs.opensolaris.org/view_bug.do?bug_id=6670866 Ross PS. You say you started e-mailing Zhang in July, wouldn't be anything to do with my e-mail to him on July 10th would it? :-D If so, please pass on my thanks to Zhang for looking into this.
