zfs discuss - Feb 2010 - rule of thumb for scrub

I think I asked this before but apparently have lost track of the
answers I got.

I''m wanting a general rule of thumb for how often to `scrub''.

My setup is a home NAS and general zfs server so it does not see heavy
use.

I''m up to build 129 and do update fairly often, just the last few
builds were a bit too problematic.

My disks are setup in 3 mirrored pairs.  They do get regular use when
my other machines access the zfs server for backups, and the nfs
served directories shared all around.

But still only home usage.... no business involved but maybe a bit of
a heavy hobbist user.

With that in mind what would be a good safe plan for `scrubbing''?

Hi Harry,

Our current scrubbing guideline is described here:

Run zpool scrub on a regular basis to identify data integrity problems.
If you have consumer-quality drives, consider a weekly scrubbing
schedule. If you have datacenter-quality drives, consider a monthly
scrubbing schedule.

Thanks,

Cindy
