Under FBSD 10 I was using it to run iSCSI using IPoIB between two boxes
(with ZFS mounted atop of that). This worked, and performance was 'good' -
but the boxes would eventually 'lose site' of each other [I think at least
one other person had the issue - worse (i.e. more often) than I did]
Knowing there's been a lot of changes to IB in 11 I thought I'd give that a
I can go back to FBSD 10 - I'd need to solve the intermittent "loses site"
issue then (with the code the 10 is running).
I guess overall - moving back to 10 is looking like the better option...
