Slow parity check

[smexyrabbi]

Hello 

 

I'm a noob at looking at logs. My parity check has been pretty slow lately averaging around 50 MB\S to 90 MB\s. I turned off all docker containers to see if they affected the speed but my results were the same.

 

Open to any suggestions :)

I have 5 drives + 1 parity drive, a mix of 8TB and 6TB.  My parity runs ~14.5 hours and averages ~150MB/s.  It has run longer, up to 16 hours, when there is other activity going on with the drives (Plex streaming movies or another PC perfo4rming a backup).

 

8TB / 16 HRs / 50-90 MB/s doesn't add up???

What do you think I should do?. It used to go up to 140MB/s a long time ago. I don't think it is my hba card.

Post your parity check history so one knows when it faltered. You do have it scheduled to run regularly, like monthly right?

 

You can see this on the Web UI by looking at parity history and posting a screenshot of the window captured. I dint know where that info might be inside the diag file, otherwise I'd look there.

as a side note i just uninstalled unassigned devices and so far my speeds are around 150mb/s

Ok I believe I solved the issue by removing the 2 unassigned devices plugins. Its been an hour and i've had 150mb /s consistently.

I'm sure most people have Unassigned Devices installed and have no problems with parity checks, so something else is going on. And nothing in your syslog about Unassigned Devices doing anything.
