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?
