-#     zfs_health.sh @ Version 0.15
-
-# Check health of ZFS volumes and drives. On any faults send email. In FreeBSD
-# 10 there is supposed to be a ZFSd daemon to monitor the health of the ZFS
-# pools. For now, in FreeBSD 9, we will make our own checks and run this script
-# through cron a few times a day.
-
-# Changelog
-# Peter van der Does - Always send an email, even if there is no problem.
-#                      I prefer to know a script has run even when there is no problem.

-# ZFS uses a copy-on-write scheme. The file system writes new data to
-# sequential free blocks first and when the uberblock has been updated the new
-# inode pointers become valid. This method is true only when the pool has
-# enough free sequential blocks. If the pool is at capacity and space limited,
-# ZFS will be have to randomly write blocks. This means ZFS can not create an
-# optimal set of sequential writes and write performance is severely impacted.

-# Scrub Expired - Check if all volumes have been scrubbed in at least the last
-# 8 days. The general guide is to scrub volumes on desktop quality drives once
-# a week and volumes on enterprise class drives once a month. You can always
-# use cron to schedule "zpool scrub" in off hours. We scrub our volumes every
-# Sunday morning for example.
-#
-# Scrubbing traverses all the data in the pool once and verifies all blocks can
-# be read. Scrubbing proceeds as fast as the devices allows, though the
-# priority of any I/O remains below that of normal calls. This operation might
-# negatively impact performance, but the file system will remain usable and
-# responsive while scrubbing occurs. To initiate an explicit scrub, use the
-# "zpool scrub" command.
-#
-# The scrubExpire variable is in seconds. So for 8 days we calculate 8 days
-# times 24 hours times 3600 seconds to equal 691200 seconds.
