Server keeps rebooting during parity check


Recommended Posts

Hi all,

 

I've just upgraded my parity drive from 3TB to 4TB, and am trying to generate parity for the new drive.

A few hours into the parity check, the server appears to reboot itself, as when I log in to check on it, I get the prompt to start the array.

Is there a way to get Unraid to automatically save the syslog to the cache drive as it generates it, or some other non-volatile location, so that I can troubleshoot this?  The logs are cleared on reboot when it crashes.

Can anyone think of a reason why it would be crashing?  I completed a full parity sync on the 3TB drive fine, so maybe there is an issue with the new 4TB drive?

Either install the fix common problems plugin and click on troubleshooting mode, or from the local keyboard & monitor

 

tail -f /var/log/syslog > /boot/syslog.txt

 

Either method will continually update the the flashdrive (logs folder if using FCP or root folder if using the command) with the syslog as it changes

 

Hopefully something will be discernable, but assuming your powersupply is up to the task, its probably going to be an issue with memory.

Thanks guys, great plugin!  It's been scanning for a few minutes now and the web GUI is now unresponsive, hopefully it finds something.  I've telnetted in and kicked off that syslog dump to the flash drive.  Either way hopefully we'll get something logged :)

The server has ECC RAM so I'd assume it isn't a memory issue?  I have a bag of spare sticks I can pop in if needed though.

It just went down, but nothing really useful:

Might run a Memtest when I get home.

When running Memtest I noticed a stick of RAM was a different brand to all the others, I've swapped it out and am re-running a parity check.  Also had Disk 3 disappear when I rebooted from doing this, re-seated the SATA cable (seemed snug, but just in case), and it's reappeared.  Given that it is another one of the dodgy Seagates I'm copying the data across to another drive just in case.

Parity sync at 10% and progressing well, see if it crashes again with the new RAM.
