I seem to be having issues with errors when i do a Parity check,   I had a couple issues with unraid crashing and had to do a hard shutdown, So i get there could be errors but i have done the party check 3 times with corrections turned on but still high errors.

 

I only have plex docker running i have switched everything else of so i am running out of ideas.  Any help would be great.

 

Should i just stop the array and format the parity drives ( if this can be done)

 

Thanks

Start by running memtest.

Which drive(s) is/are the read errors on? I only see a few that are drive level (on disk 2 and 4), which makes me think you may have a bad cable and/or card if they're occurring continually. Try reseating your card and if you have spare cables for drives 2 and 4, replacing those and running parity again.

 

Also you may want to run it without corrections first; opinions vary on that, and realistically since you've run it a few time with it checked it makes little sense to bother now, but in future, so if it is just a bad cable or something similar, you aren't altering parity. Personally I run my monthly checks without, that way if there are errors I can determine the cause and run again before writing corrections.

24 hours of being off.  yay! lol

 

I did add 32gb ram and a GPU but i had issues with VM's but maybe a memory issue.  (Good Shout)

Ok i will take card out and put back in too.

 

I didn't know any of the drives had issues as the gui is not reporting anything.

 

I do also run Parity checks on a monthly basis but where i had to button it a couple times

The SMART reports in your zip file show a small number of read errors. Not enough to worry about IMO unless you keep getting them on those drives.

This is the GUI annoying it doesn't say any errors lol.

SMART reports cover the history of the drive; the UnRAID gui errors are reset when the array is rebooted.

(also UnRAID read errors aren't often on the drive level, so any read errors on the drive are usually lower)

Ok good to know.  I will do a memory test and check all connections.

Does a memory test last 24 hours or can you do say 12?

I have 128gb of RAM and memtest takes about 12 hours per pass.

ok cool i have 64gb so should be ok.

 

Thanks

when i run the mem test it just says Loading /memtest.... ok 

 

Is this normal or should i see more lol

Make sure you're booting using legacy BIOS/CSM, memtest doesn't support UEFI boot.

My bios has UEFI or legacy and UEFI which is on but still hags

ok downloaded mem test and put on separate memory stick so its running lets see what happens.

Any other ideas if the memory comes back fine?

so first memory test is fine.  now to do the 64gb all together.

Low and behold i got an error within 20 minutes with 64gb ram in.  I am now testing the 32gb ram i got the other day on its own.  Hopefully in a way it errors so i can send it back.

Just an update.  Tested both 2 x 16gb on there own no issue..  Had a friend of mine said to increase voltage on memory.

 

WIll test again tomorrow see if i get the issue then up the voltage and try again.

 

Fingers crossed.

So i found out that the new memory that was sent was a different speed and because i was using XMP i think that why i was getting memory issues.

 

After setting voltage to 1.35 and memory speed to the lower 2666 seem to have no issues there.

 

However when i did a parity check with corrects i still got 400 errors.  When i ran it with no corrections it  reported no errors :/

Any ideas?

It's normal for the first check after the issue is fixed to still find errors, next ones should not find any.

i know but i ran a few times.  Ill see what happens when it runs at the end of the month

The beginning i ran the corrections about 4 times and still got errors. Now i seem to have fixed memory issue so maybe that will sort it.

 

If honest lost count the amount of parity checks i did. was loads and lots of time.
