Parity check slow since HW upgrade

Featured Replies

Hello - I recently updated my CPU/MB/RAM/GPU when my son built himself a new PC.  Unfortunately I don't have the old specs, but the new specs are:

MB: ASUSTeK COMPUTER INC. - PRIME B550M-A

RAM: 32GB (4x8GB) DDR4

CPU: AMD Ryzen 5 2600 Six-Core Processor

GPU: NVIDIA GeForce RTX 3060

 

None of the drives have changed (I replaced a bad cache drive since the HW upgrade, but nothing has changed with the speed of the parity check.

The drives are a single 6TB parity drive, and 4 drives in the array (2x 6TB and 2x 4TB = 20TB) with a 500GB SSD Cache drive.

 

Currently the parity check is running at <60 MB/sec, and will take ~30 hours at the current pace.   Before the HW change, it would run ~110 MB/sec and finish 14-15 hours.

I'm not sure whether something should be done, or what that would be, but I pulled diags when the most recent parity check started and have attached them here.  Any advice greatly appreciated.

You have a controller with a SATA port multiplier, and it's using the same port for all connected disks, since there's an extra board port, connect one disk there and try connecting the other two to to different main ports.

Unfortunately the board only has 4 SATA ports, so I will move 1 to the open port (I had an unused cable I removed and didn't think to move one from controller).  Is it better to have specific drives connected directly to the board vs. not?

Doesn't really matter.

This worked wonders....2 completed checks since moving 1 SATA cable directly to the board have been more than 2x quicker.

Thank you so much @JorgeB.
