Parity check running very slow (kb/s)

[Ibis]

 I am still somewhat new to Unraid I have just added 3 new disks to my array, and it is running the Parity check but is running at maximum 400kb/s and is saying it will take over 200 days to complete. I have 2 10tb drives for parity and 11 drives total in the array (4x 8thh and 7X10tb) 

 

I stopped all dockers and it did not change the speed. I tried stopping and restarting the parity check and still did not improve the speed. 

 

Thank you for your help 😀

You've got to reseat the cabling to both ST10000VN0004-1ZD101  ZA29CF7E (disk 10),  and ST10000VN0004-1ZD101   ZA2AJ2XJ (disk 11)

 

Sata is finicky at times and it doesn't take much for continual resets to happen on a slightly misaligned cable (or a bad cable)

Thanks, I have reseated the cables on both and now running at maximum 2mb/s

I just stopoped the dockers as well and it is now running at about 4mb/s

nevermind, it just needed a min and now its running at 100mb/s

Sorry to be a pain it is fluctuating a lot as low as 1mb/s but up to 100mb/s I have tried looking at the logs myself but don’t know what I am looking for. 

I restarted the sync about 21 hours  45 mins ago and has done 8%

According to your syslog it look like a couple of disks had connection problems, and then disk11 dropped offline, and later reconnected with a different device ID so it now showing up under Unassigned Devices (Unraid cannot is not hot-plug aware for array devices and cannot handle this so it thinks it has failed).

 

As was mentioned previously you need to carefully check the cabling (both power and SATA) to make sure all cables are properly seated.   Also are you sure your power supply is up to handling all the drives you now have connected?

I would appreciate if someone could have another look for me. I have replaced all SATA Cables and am still only getting 500kb/s speeds for parity sync. I'm worried I will have a drive fail before the parity has has been built. 

 

Thank you for your help.

Constant errors in multiple disks, this is usually a power/connection problem.
