I have a raidz1 tank of 5x 640 GB hard drives on my
newly installed OpenSolaris 2009.06 system. I did a
zpool export tank and the process has been running
for 3 hours now taking up 100% CPU usage.
When I do a zfs list tank it's still shown as
mounted. What's going on here? Should it really be
taking this long?
$ zfs list tank

Can you run the following command and post the
output:
# echo "::pgrep zpool | ::walk thread | ::findstack
-v" | mdb -k
Thanks,
George

Here's what I get
# echo "::pgrep zpool | ::walk thread | ::findstack -v" | mdb -k
stack pointer for thread ffffff00f717b020: ffffff0003684cf0
ffffff0003684d60 restore_mstate+0x129(fb8568ee)
It might be best to generate a live crash dump so we can see what might
be hanging up. You can also try running the command above multiple times
and even run 'pstack <pid of zpool>' to see if we get additional
information.
Thanks,
George
