Full Description:
Creating a zfs test pool on file based, then removing one of the
underlying files
and doing a zpool scrub causes kernel panic.
How to repeat the problem:
To reproduce create two files, then zpool tank pool on files
# dd if=test1 count=100k bs=1k
# dd if=test2 count=100k bs=1k
# zpool create tank mirror /root/test1 /root/test2
now remove file /root/test2, this causes a kernel panic
# rm /root/test2
# zpool scrub tank
