I am setting up a new RaidZ2 pool consisting of seven brand-new ST8000DM004 drives. All (plus a spare) passed initial S.M.A.R.T. (short, long, and conveyance) and badblocks testing, but now, while populating the new pool by means of zfs send / recv from an over-full smaller pool, I'm getting a report of 8 unreadable / uncorrectable sectors on one of the new drives.
Quite apart from the issue of whether I return the drive (and buy a new one at a now-increased price, if they will not simply replace it without paying more) or RMA it with Seagate (and receive a "refurbished" -- i.e., more thoroughly tested -- replacement), would it be OK to replace the drive by the spare now, or should I wait until the new pool has finished populating?
