Crash reports.

Hi.

Have had freenas crash a few times.

The first one, I'm not sure which version it was. It was from a while ago. It seemed to crash out of the blue. It wasn't responding, and when I checked the physical monitor, I saw the kernel panic.

First crash:




The second one was while running 8.3.0-release-x64 (12701m). I was trying to start a resilver on one of the pools.

Second crash:



Any idea on what caused these? After the event, I'm not sure what I can do to help diagnose what caused the problem.

System specs:

i5-3570k
Asus P8Z77-V LK
32 gb ram.
Integrated realtek nic
offboard intel CT nic
IBM M1015 flashed to IT mode.

2 zpools:

Pool A: 10x 3tb seagate's in RaidZ3

Pool B: 2x 1.5tb wd's in Mirror.

The first one was hardware. A disk went out to lunch and the filesystem code got unhappy/confused/cranky and the system paniced to avoid corrupting any filesystems.

The second one could be hardware or software. Is it still sitting at the debugger prompt?

On the first one, simply rebooting it wasn't enough. It failed to boot back up. I had to reflash the usb flash drive, and restore from a config.

For the second one, simply rebooting it brought it back up. So, no, I didn't leave it at the debugger prompt.

If it still was, what would I have done to 'dig deeper'?

Got another crash, similar to the second one in my first post.

Here's a screenshot.

It's still sitting at the db> prompt. Is there anything I can do to backtrack what went wrong?

This seemed to occur during a gui initiated disk replace. I clicked replace disk and chose the replacement disk. After it seemed like it was taking a while, I noticed my ssh session had frozen. Checked the console, and saw the crash.


Hardware specs above.

PoolA is the same as above. 10x 3tb in raidz3.

PoolB is now 5x 1tb in raidz1. Backup only, not worried about data loss. This was the pool I was running the disk replace on.

Freenas version 8.3.1-rc1 x64.

Have you tried a RAM test?

 

[titan_rw]

No, I don't think I have on this machine.

I'll PXE boot memtest and give it a few passes.

 

[titan_rw]

Ran two passes of memtest. No errors.

I guess I'll see if I can break it again.
