It is the second scrub against that data set. The errors that remained after the first scrub (above) have vanished. I'm a little confused although I often run multiple fsck against volumes before entering multi-user mode. That said, during this scrub the system froze twice requiring a reboot. This is now a common problem across my four AMD systems: one eight core x1 8150, one 16 core x1 6272, one 16 core x2 6274, and one 16 core x4 6274. (3x r241015M and 1x r241040). bd3# zpool status -v disk-1 pool: disk-1 state: ONLINE scan: scrub repaired 0 in 30h18m with 0 errors on Wed Oct 3 09:44:29 2012 config: NAME STATE READ WRITE CKSUM disk-1 ONLINE 0 0 0 raidz2-0 ONLINE 0 0 0 da0 ONLINE 0 0 0 da1 ONLINE 0 0 0 da13 ONLINE 0 0 0 da2 ONLINE 0 0 0 da3 ONLINE 0 0 0 da4 ONLINE 0 0 0 da5 ONLINE 0 0 0 da8 ONLINE 0 0 0 da9 ONLINE 0 0 0 da10 ONLINE 0 0 0 da11 ONLINE 0 0 0 logs gpt/zil-disk1 ONLINE 0 0 0 cache ada0 ONLINE 0 0 0 errors: No known data errors -- Dennis Glatting <dg@pki2.com>
