Parity Check stuck at random percentages, cannot Pause or Cancel parity check once it's stuck

Featured Replies

This has been an on going issue for months, I've swapped basically everything, I'm not sure what else to do.  I've attached a diagnostic log to see if anything there helps.  This time the parity check is stuck at 10.3% and the estimated finish has now extended to 600+ days.

Ok, give me a min, the unraid firefox browser won't let me attach the file right now.  I'm going to reboot and attach after this post.

Unraid driver is crashing, start by running memtest.

I haven't had time to do an actual mem test, but this is what I've done so far. Hope this provides some feedback value.

 

In the bios I disabled all automatic ram options and set them all to default or stable. 

The system has 2x 32gb ram sticks. I was able to run the system on a single stick and remove the opposite stick, then vice versa. Both scenarios ended up having the same result, getting parity check stuck at random percentages. 

 

I chose this way first as it only has a few min downtime vs a mem test which could have 24-48hrs of down time.

 

I'm willing to purchase additional ram rather than take the system offline. 

 

Let me know what you think.

Still crashing.

Any suggestions on what to try next?

You shouldn't even attempt to run any computer unless memory is working perfectly. Everything goes through RAM, the OS and other executable code, your data, everything. The CPU can't do anything with anything until it is loaded into RAM.

Would it make sense that both sticks are faulty?

 

And all my years of building computers. I've never ran into a faulty ram stick. What are the chances of both of them being bad??

That's unlikely, though there could still be a different issue, since I've seen this crashing happening before with some kernel/board combos it could also be a compatibility issue, I would try with Unraid v6.11.5 which users a very different kernel, if it's the same it's likely hardware related.

I downgraded to 6.11.5, started a parity check which got stuck again. 

 

Since I have swapped everything except the motherboard and CPU. I would assume it has to be one of those. How do I know which?

Most likely, I would say the board is more likely since it's more common to have a bad board than a bad CPU, but it could be either.

I have a known good mb/CPU/ram that I can swap out. It it currently in use for unraid with a similar setup, but should help rule out those components.

Did you ever find a solution to this?
