Hi,
I scrub my pools once a week on the weekend, rpool saturday, cesspool
(my other pool) Sunday. You can still use the box while it is
scrubbing but as you would expect the I/O is very slow and can
sometimes be close to unusable.
Ta,

Hi all,
I have a Thumper (ok, actually 3) with each having one large pool,
multiple filesystems and many snapshots. They are holding rsync
copies of multiple clients, being synced every night (using
snapshots to keep ‘incremental’ backups).
I’m wondering how often (if ever) I should do scrubs of the pools,
or if the internal zfs integrity is enough that I don’t need to do
manual scrubs of the pool? I read through a number of tutorials
online as well as the zfs wiki entry, but I didn’t see anything very
pertinent. Scrubs are I/O intensive, but is the Pool able to be used
normally during a scrub? I think the answer is yes, but some
confirmation helps me sleep at night.
Thoughts? Ideas? Knife-fights?
Thanks
Dave
