First...the bad news:
I'm seeing between 1MB and 10MB/sec resilver speed on an 18 drive raidz2 setup. Typically the speeds hover around 1-2MBps.
13.8GB in 30 minutes
The pool was created with ashift=12.
Drives are all 8TB WD Red 5400 RPM drives
E5-2630L v3, 128GB of ram
Truenas release version.
tunables:
vfs.zfs.resilver_min_time: 6000
vfs.zfs.resilver_delay: 0
vfs.zfs.top_maxinflight: 512 (raised from 128)
vfs.zfs.scrub_delay: 2
There has to be something wrong here. at this speed, it's going to take like 2 weeks to replace this drive?
