CFT: periodic scrubbing of ZFS pools

[Alexander Leidinger]

Hi,

as there seems to be interest in a periodic script to scrub zpools, I  
modified my monthly-POC into a daily script with parameters for which  
pools to scrub, how many days between scrubs (even different per pool,  
if required), and several error checks (non-existing pool specified,  
scrub in progress).

You can find it at
    http://www.Leidinger.net/FreeBSD/current-patches/600.scrub-zfs

Please put it into /etc/periodic/daily and test it. Possible  
periodic.conf variables are:
  daily_scrub_zfs_enable="YES"
  daily_scrub_zfs_pools="name1 name2 name3" # all if unset or empty
  daily scrub_zfs_default_threshold="<number_of_days>" # default: 30
  daily_scrub_zfs_<POOLNAME>_threshold="<number_of_days>"

If there is no specific threshold for a pool (= days between scrubs),  
the default threshold is used.

Bye,
Alexander.
