Parity Syncing at 800kb/s

[jbrukardt]

Diagnostics are attached,

 

Something glitched and I lost a parity drive (Parity 1), physical failure, and then subsequently during the parity rebuild after physical replacement I had another disk "disabled", Disk 7.   I checked SMART on the disk and it seemed fine, so i unassigned it, cycled the array, reassigned it, and booted the array back up.  

 

Upon letting the array start up, it seems to be in a bad place.  Parity sync is occurring @ 800 kb/s and will take 100 days to complete.   

 

8 TB

Elapsed time:21 minutes

Current position:1.33 GB (0.0 %)

Estimated speed:785.6 KB/sec

Estimated finish: 108 days

 

All these drives were precleared about 2 weeks ago, had roughly 80TBs of data written to them, and then the parity drive failure occurred.

This happening for multiple devices:

Oct 29 20:05:29 Tower-Transfer kernel: sd 1:0:4:0: Power-on or device reset occurred
Oct 29 20:05:29 Tower-Transfer kernel: sd 1:0:7:0: Power-on or device reset occurred
Oct 29 20:05:29 Tower-Transfer kernel: sd 1:0:1:0: Power-on or device reset occurred

 

usually suggests a power/connection problem.

Shoot, I see it in syslog all over the place.  Doesn't seem to be on a single minisas, so I expect the controller may be overheating, or I have bad power connections.

 

It does have a few splitters in it, but it's unavoidable with this PSU.

It's detecting new errors after the correcting check, start by running memtest.
