>Description:
I created two zfs vdevs with mkfile, then created a zpool mirror. Attempting to offline one of the devices will result in a system crash and reboot.
#####
(root@v2) ~/t#mkfile 100m a
(root@v2) ~/t#mkfile 100m b
(root@v2) ~/t#zpool create u3 mirror ~/t/a ~/t/b
(root@v2) ~/t#zpool status u3
pool: u3
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
u3 ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
/root/t/a ONLINE 0 0 0
/root/t/b ONLINE 0 0 0
errors: No known data errors
(root@v2) ~/t#zpool offline u3 /root/t/b
>How-To-Repeat:
