Crash and cores since TrueNAS-12.0-U3.1 upgrade

[vthinsel]

Hello,

I upgraded to TrueNAS-12.0-U3.1 on the 5th of May, and since 15th of May I get regularly python3.8.core alerts :

Code:

New alerts:
The following system core files were found: python3.8.core. Please create a ticket at https://jira.ixsystems.com/ and attach the relevant core files along with a system debug. Once the core files have been archived and attached to the ticket, they may be removed by running the following command in shell: 'rm /var/db/system/cores/'.

In addition, I also get a daily unscheduled reboot:

Code:

* freenas.thinselin.local had an unscheduled system reboot.

The operating system successfully came back online at Tue May 18 09:01:53 2021.

* freenas.thinselin.local had an unscheduled system reboot.

The operating system successfully came back online at Mon May 17 07:44:42 2021.

* freenas.thinselin.local had an unscheduled system reboot.

The operating system successfully came back online at Sun May 16 21:59:32 2021.

My dmesg is here for details : https://gist.github.com/vthinsel/c878b56855d13ef40e4c22d0d9b620c9
Any idea on what could cause this issue ?

We're currently investigating what I assume is the same issue in Jira:

https://jira.ixsystems.com/browse/NAS-109709

If you want to attach a debug there and continue the conversation that may help us get to the bottom of this issue/

 

[vthinsel]

Sure. The core file is here : https://drive.google.com/file/d/1BEHlkC3TamnzT-y-ghiA7MWIn3uSmo1Y/view?usp=sharing
I have applied the fix as per https://jira.ixsystems.com/browse/NAS-109709
Lets wait now.

Hum. After applying the patch, my box doesnt boot properly. I get a mountroot> prompt
Loader variables:
vfs.root.mountfrom=zfs:freenas-boot/ROOT/12.0-INTERNAL-U3-py39_3
panic: mountroot: unable ro (re-)mount root

Any idea to rollback ?
thanks

Just went through the boot menu to revert to U3.1

 

[vthinsel]

Even after reverting to U3.1 I still get crash. Got one while console was on.

Well, looks like a faulty memory stick. Bad coincidence I guess, sorry.
