>Description:
800.scrub-zfs is a periodic script you can enable to perform periodic scrubs of
ZFS filesystems. If you have faulted zpools the script generates sh errors due
to some of the zpool commands generating no output.
Faulted zpools can happen for reasons other than hardware failure, for example
if you use ZFS on removable devices when they are unplugged zpool status will
show them as faulted.
>How-To-Repeat:
Put ZFS on a removable device, export and detach it from the system.
# echo 'daily_scrub_zfs_enable="YES"' >> /etc/periodic.conf
# /etc/periodic/daily/800.scrub-zfs
>Fix:
