Hi,
We have been running LXC/LXD containers for several years now our servers.
Today after updating Ubuntu 22.04 LTS and upgrading LXD to 5.8 we are getting errors when processes create new files in our containers → “Value too large for defined data type”.
The containers are in “running” state.
Editing existing files like /var/log/syslog or /.bash_history have no problem.
However our own and other software is unable to start as it gets the “Value too large for defined data type” error while starting.
We have searched this forum and in other places, but nothing seems to be related to our situation.
Host details:
OS: Ubuntu 22.04.1 LTS
kernel: Linux five 5.15.0-53-generic #59-Ubuntu SMP Mon Oct 17 18:53:30 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
storage: ZFS
Container details:
OS: Ubuntu 22.04.1 LTS
Example of errors in syslog of the container:

Some information about the config:
- the container was manually upgraded to 22.04
- security.nesting: “true” was added to help resolve the issue mentioned above, but it did not.
Restarting the container is not helping. As we read in another post this might help in remapping the filesystem.
Reverting to LXD 5.7 also did not help.
Is this issue security related or what could be the cause?
Please let us know if more information is needed.
Thanks for any advice.
