Hi,
I've got an OpenSolaris 2009.06 box that will reliably panic whenever
I try to import one of my pools. What's the best practice for
recovering (before I resort to nuking the pool and restoring from
backup)?
Could you please post panic stack backtrace?
There are two pools on the system: rpool and tank. The rpool seems to
be fine, since I can boot from a 2009.06 CD and 'zpool import -f
rpool'; I can also 'zfs scrub rpool', and it doesn't find any errors.
Hooray! Except I don't care about rpool. :-(
If I boot from hard disk, the system begins importing zfs pools; once
it's imported everything I usually have enough time to log in before
it panics. If I boot from CD and 'zfs import -f tank', it panics.
I've just started a 'zdb -e tank' which I found on the intertubes
here: http://opensolaris.org/jive/thread.jspa?threadID=49020. Zdb
seems to be ... doing something. Not sure _what_ it's doing, but it
can't be making things worse for me right?
Yes, zdb only reads, so it cannot make thing worse.
I'm going to try adding the following to /etc/system, as mentioned
here: http://opensolaris.org/jive/thread.jspa?threadID=114906
set zfs:zfs_recover=1
set aok=1
Please do not rush with these settings. Let's look at the stack
backtrace first.
Regards,
Victor
