Kernel Panic, using 12.0

[ismith.hpu]

Hi Free/TrueNAS community,

I am having trouble with utilizing FreeNas on the following hardware and I have attached the crash dump.

The crash happens when I attempt to connect my VEEAM server on Windows 2019 via NFS by: 10.33.102.26:/mnt/archive/nfs_archive
I have disabled zfs sync



OS/HW information:

1. OS Version: TrueNAS-12.0-MASTER-202003240424
   1. *******Note: 11.3 crashes with a kernel panic, and so did 11.2
2. H740P is in HBA mode with a single virtual disk with the 2x240G SSDs in RAID1.
3. BIOS is NOT in UEFI mode.
4. I am using the 1Gb port currently until new network hardware comes in.

My Pools are:
11x2.4TB + 1x2.4TB hot spare @ raidz2 using lz4, FreeNAS sees the bare metal drives.

Can you enable the debug kernel and get another crash dump?

 

[ismith.hpu]

Is there a way to do that via the WebUI or only upon boot up?

 

[ismith.hpu]

Additionally, from the iDRAC: when I rebooted and just idling clicking through the WebUI

 

[freqlabs]

System / Advanced

 

[ismith.hpu]

I am there.

Do I then reboot into normal kernel and pull the log? New to FreeNAS and not sure.

 

[freqlabs]

Sure, that works.

 

[ismith.hpu]

Using the BT command, pulling the log in a second.

 

[ismith.hpu]

There is no difference in the two files unless I pulled the debug_kernel logs incorrectly.

Is there a guide or resource you can point me towards in assisting you guys helping me?

 

[freqlabs]

This is a completely different panic. Since you're having crashes with every version of FreeNAS, maybe this is actually a hardware issue?

 

[ismith.hpu]

Yeah I will do a memory test to see what is going on.

 

[ismith.hpu]

I am able to use SMB without crashing? @freqlabs

 

[ismith.hpu]

Booting to do a mem-test currently.

 

[freqlabs]

Is there a guide or resource you can point me towards in assisting you guys helping me?

The best way to help is to open a ticket at http://jira.ixsystems.com/ describing the issue, and upload a debug archive from System / Advanced / Save Debug

Thank you
