Backup to TrueNAS SMB Share stopped working

[Murlock]

Hi all, New User here. I've been backing up all my VM's and containers to a TrueNAS Scale SMB share for a few months and recently updated Proxmox to 8.2.2

Since then my backups have stopped working although I've changed nothing on either one (Proxmox or Truenas).

This is the output I'm getting

INFO: starting new backup job: vzdump 100 --compress zstd --notification-mode auto --storage TrueNAS --mode snapshot --notes-template '{{guestname}}' --node proxmox --remove 0
ERROR: Backup of VM 100 failed - unable to create temporary directory '/mnt/pve/TrueNAS/dump/vzdump-qemu-100-2024_05_06-14_54_50.tmp' at /usr/share/perl5/PVE/VZDump.pm line 1055.
INFO: Failed at 2024-05-06 14:54:50
INFO: Backup job finished with errors

Likewise if I try to upload an ISO to TrueNAS I get this output.

starting file import from: /var/tmp/pveupload-c31282611e149c894e75af54ce72a764

TASK ERROR: import failed: cp: cannot create regular file '/mnt/pve/TrueNAS/template/iso/ubuntu-24.04-live-server-amd64.iso': Permission denied

Can anyone Help please?
I've been pulling my hair out to try and solve it, but to no avail.

Thanks in advance.
Murlock.

Check the free space on your root filesystem, might be nearly full
You're also getting a Permission Denied so check chown / chmod permissions on that directory

I am also in the same boat. I did not have this issue with either CIFS/SMB or NFS and now I'm seeing with both. My ownership/permissions are check out fine.

I would recommend filing a bug report on the proxmox bug tracker then:

https://bugzilla.proxmox.com/

Hi, just a quick question for you.
Are you running an AMD system?
Mine is in a Minisforum UM773 Lite.
Ryzen 7 7735HS.
I'm wondering if its a bug with the AMD side.
