Call Trace and Network interface Drops during parity check

[SimonF]

Any suggestions on call trace and network interface up and downs whilst doing parity check. My Win10 VM also became unresponsive with 100% on one of the CPUs.

 

Machine is ok all the time, issues only appear during check.

The Intel NIC related call trace is quite common:

 

Dec  7 09:18:34 unraid kernel: NETDEV WATCHDOG: eth0 (igb): transmit queue 1 timed out

 

But all the subsequent NIC resets are not so normal, reboot and see if it happens again during the next parity check, or before.

 

 

 

Also you have read/write errors on one of your pool devices:

Dec  4 08:13:59 unraid kernel: BTRFS info (device sdi1): bdev /dev/sdj1 errs: wr 40846, rd 4546, flush 115, corrupt 0, gen 0

P.S: There were some parity sync errors, were those expected?

Thanks I will review your feedback I have just updated BIOS so see if that helps also. Sync errors may have been due to power outage, I am running another check.

$150 UPS has saved me endless aggravation and headaches. It's easily worth putting off purchasing extra drives for it. I always highly recommend one.
