System unresponsive/crashes during parity sync?

Featured Replies

Hello,

 

I've been trying to do a parity build for the last day or so, but it seems my system stops and becomes completely unresponsive after ~6 hours.

 

The first time, I attempted to do a parity build while doing a pre clear as well, and just around the 6 hour mark everything completely froze. I couldn't telnet in, I couldn't reach unraid through the web, and I also couldn't access IPMI.

 

Similarly the 2nd time (same situation -- with preclear running). Both times I was unable to capture a log since I could not access the machine at all.

 

The third time I tried it without preclear running, and I also ran a tail on the log and I have that captured below -- it doesn't show much

 

All 3 times, after it stops, there is no disk activity (or at least the green light is no longer spinning.

 

I've run 5 pass throughs in memtest so far, with no errors there. i'll continue running it until I have some suggestions on what to try

 

Thanks!

 

My unRaid version is 5.0-rc11

Update:

 

Booted into unraid...that drive is failing bad now.

» current_pending_sector=53

» offline_uncorrectable=52

 

Anyone know the procedure for uh.......reattaching its external case and hoping for a warranty replacement? :P

Clearly this drive isn't going to work in UnRAID.    The risk you take when you buy an external drive and pull it from the case is exactly what you've now encountered.    You can type in the drive's serial number to the manufacturer's warranty check site and see if they'll cover it under warranty ... but you may simply be out-of-luck unless you removed it VERY carefully and can reassemble it in the original case for a warranty repair.

Yup -- thats exactly what happened.

 

These drives actually came from before i had unRaid. It is still under warranty...but I'd have to put it back together.
