Hi guys, 

Around a month ago I started seeing very slow parity check speeds, around 12-13 mb/s.

Also I started using LSI 9207-8i card to be able to plug in more devices, I though i may help with the slow parity check for some reason. 
When I tried it the first time every disk was mounted, there was no problem but as soon I started partoy check disk 3 became unavailable. Now I reverted and plugged all HDDs to motherboard directly, and started rebuilding disk 3, but rebuilding speed is barely 1 mb/s. I stopped dockers and vms
I am a bit of a novice, can you help me? 

 

I have attached diagnostics. 

 

Thanks.

Connection problems with disks 1 and 2. Stop rebuild, fix connections, try again.

I changed the sata cables and it seems to be working thank you. 

How did you see that error I would like to spot his myself next time? 

 

Also, do you have any ideas why LSI sas card caused disk 3 problem?

Not unless you have diagnostics or syslog from before you rebooted.

EDIT: I started docker containers and the speed went down to ~15mbps, and I saw the following failed commands on logs window. 
Now I stopped the docker and the speed is around 140mbps

Attach new diagnostics to your NEXT post in this thread.

Hi, 

I tried changing the placement of the hdds and ATA failed error changed with it, I changed all the cables, and the issue is still there.  So i'm guessing the harddrive itself is has a I/O problem. 

Can it be that?
