I have RAIDZ from 4x ST4000VN000-1H4168 SC43 and the speed of scrub is about 20MB/s. Scrub takes more than week to finish: pool: tank0 state: ONLINE status: Some supported features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(7) for details. scan: scrub repaired 0 in 262h56m with 0 errors on Sun Sep 16 02:04:25 2018 config: NAME STATE READ WRITE CKSUM tank0 ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 gpt/disk0tank0 ONLINE 0 0 0 gpt/disk1tank0 ONLINE 0 0 0 gpt/disk2tank0 ONLINE 0 0 0 gpt/disk3tank0 ONLINE 0 0 0 This is on HP ProLiant ML 110 G5 (very old machine) with only 5GB of RAM.
