[SOLVED] Snapshot lxc-freeze not possible since upgrade

[MH_MUC]

Hi everyone. I updated to the latest version yesterday (pve-manager/6.2-4/9824574a (running kernel: 5.3.18-3-pve)).
However since the system is in production I didn't reboot into the new kernel.

Tonights upgrade failed with
ERROR: Backup of VM 100 failed - command '/usr/bin/lxc-freeze -n 100' failed: exit code 1

I tried to clone the container to see if it would boot up again, but this didn't work, because snapshotting is failing with the lxc-freeze failure as well.

I am not quite sure what to do now. Rebooting seems to be risky, because I am not quite sure that the CT is coming back up again. Any idea? Thanks!

Hi,

A reboot with kernel updates is always necessary to take all effects, so i seen some users have same your issue take a look [0],[1] maybe that helps you

Hi Moayad, I am sorry for double-posting. I just found that post as well and was about to mark this one resolved.
I just rebooted the server and everything is working fine now.
