Hi ProxMox Forums,

I am trying to restore an LXC container to a new host and encountering an error. Similarly sized VMs have restored fine but this LXC backup keeps encountering the following error (Names adjusted):
Code:
Virtual Environment 8.1.4
Storage 'RESTORE_ONLY-PBSServer' on node 'HOST2'
recovering backed-up configuration from 'RESTORE_ONLY-PBSServer:backup/ct/110/2024-03-27T16:00:35Z'
  Logical volume "vm-111-disk-0" created.
Creating filesystem with 41943040 4k blocks and 10485760 inodes
Filesystem UUID: 5b09824b-5d64-4aca-b2cb-7e4a753d5535
Superblock backups stored on blocks:
    32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
    4096000, 7962624, 11239424, 20480000, 23887872
restoring 'RESTORE_ONLY-PBSServer:backup/ct/110/2024-03-27T16:00:35Z' now..
Error: error extracting archive - encountered unexpected error during extraction: error at entry "libzstd.so.1.5.4": failed to extract file: failed to copy file contents: No space left on device (os error 28)
  Logical volume "vm-111-disk-0" successfully removed.
TASK ERROR: unable to restore CT 111 - command 'lxc-usernsexec -m u:0:100000:65536 -m g:0:100000:65536 -- /usr/bin/proxmox-backup-client restore '--crypt-mode=none' ct/110/2024-03-27T16:00:35Z root.pxar /var/lib/lxc/111/rootfs --allow-existing-dirs --repository root@pam@10.10.0.224:backups' failed: exit code 255

The final line seems to be somewhat of a nothing error, but the error before it mentions "No space left on device (os error 28)" which I suspect is the root cause
I am restoring from a 500GB Restore Volume (RESTORE_ONLY-PBSServer) to a LVM-Thin 8TB volume
The container is 161.67GB in size

The PBS itself is just installed on a 40GB drive, could this be the source of the issue?
I am fairly new to PBS but I would think if it needed to extract the compressed back up it would do so on either the destination or restore volume not the OS Disk?

I'm running the latest version of each, I have tried with a smaller container and it worked without issue, just seems odd to me that the small PBS OS Disk would be the cause.
I will be resizing the OS Disk here shortly and will return with the results.

In the interim, any assistance or advice would be most appreciated!

Thank you,
lThornl

UPDATE: I was able to restore to an entirely different host, not sure what was wrong with the one I was using.
