I just witnessed a resilver that took 4h for 27gb of data. Setup is 3x raid-z2 stripes with 6 disks per raid-z2. Disks are 500gb in size. No checksum errors. It seems like an exorbitantly long time. The other 5 disks in the stripe with the replaced disk were at 90% busy and ~150io/s each during the resilver. Does this seem unusual to anyone else? Could it be due to heavy fragmentation or do I have a disk in the stripe going bad? Post-resilver no disk is above 30% util or noticeably higher than any other disk. Thank you in advance. (kernel is snv123) It surely seems a long time for 27 gigs. Scrub takes its time, but for this 50TB setup with currently ~29TB used, on WD Green drives (yeah, I know they're bad, but I didn't know that at the time I installed the box, and they have worked flawlessly for a year or so), scrub takes a bit of time, but nothing comparible to what you're reporting scrub: scrub completed after 47h57m with 0 errors on Fri Sep 3 16:57:26 2010 Also, snv123 is quite old, is upgrading to 134 an option?
