I thought r236884 requiring a zpool upgrade was the culprit, but
it wasn't. Still stuck at a mountroot prompt (but now I have gjb's
liveCD so I can do something about it).
Something looks off with zdb -l on CURRENT and STABLE/9. Example
on my 9-stable box:
# uname -a
FreeBSD forza.west.isilon.com 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #0
r+2fd0a57: Mon Dec 3 12:02:18 PST 2012
gcooper@forza.west.isilon.com:/usr/obj/usr/src/sys/FORZA amd64
# zdb -l sac2
cannot open 'sac2': No such file or directory
# zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
sac 95G 69.7G 25.3G 73% 1.00x ONLINE -
sac2 232G 117G 115G 50% 1.00x ONLINE -
I'm running into the same behavior before and after I upgraded sac/sac2.
My git branch is a lightly modified version of FreeBSD, but
doesn't contain any ZFS specific changes (I can point you to it if you
like to look at it).
Would appreciate some pointers on what to do next.
Thanks,
