Hi,
I was using for quite awhile OpenSolaris 2009.06
with the opensolaris-provided mpt driver to operate a zfs raidz2 pool of
about ~20T and this worked perfectly fine (no issues or device errors
logged for several months, no hanging). A few days ago I decided to
reinstall with the latest OpenSolaris in order to take advantage of
raidz3.
Just to be clear... The same setup was working fine on osol2009.06,
you upgraded to b127 and it started failing?
Did you keep the osol2009.06 be around so you can reboot back to it?
If so, have you tried the osol2009.06 mpt driver in the
BE with the latest bits (make sure you make a backup copy
of the mpt driver)?
What's the earliest build someone has seen this
problem? i.e. if we binary chop, has anyone seen it in
b118?
I have no idea if the old mpt drivers will work on a
new kernel... But if someone wants to try... Something
like the following should work...
# first, I would work out of a test BE in case you
# mess something up.
beadm create test-be
beadm activate test-be
reboot
# assuming your lasted BE is call snv127, mount it and backup
# the stock mpt driver and conf file.
beadm mount snv127 /mnt
cp /mnt/kernel/drv/mpt.conf /mnt/kernel/drv/mpt.conf.orig
cp /mnt/kernel/drv/amd64/mpt /mnt/kernel/drv/amd64/mpt.orig
# see what builds are out there...
pkg search /kernel/drv/amd64/mpt
# There's probably an easier way to do this...
# grab an older mpt. This will take a while since it's
# not in it's own package and ckr has some dependencies
# so it will pull in a bunch of other packages.
# change out 118 with the build you want to grab.
