Backup of some machines failes

Hi there
I have connected a USB HDD directly to a VM that runs Openmediavault. I have added a folder to that HDD as CFIS/SMB device for backups.
I am able to make backups of some LXS with success to this folder, but one LXC is larger than 3 GB and it failes permanently - i tried both, suspend and stopped mode.
The backup begins and after approx. 2.4 GB it "hangs", and the SMB share is ... gone? I need to stop the backup manually as it never ends and restart the VM with openmediavault to get the SMB share back. When I send larger files like 10GB via SMB with no issue from windows, the size of the backup dows not seem to be the isseu I guess

Any suggestions - if so... please use simple words... I am a total newby to PM and linus in general... I need low low low level support... yes, the poswer cable is connected :)
Thanks

Hello

I would recommend you
  • Listen to the journal with journalctl -f
  • Attempt an backup
  • Post the output of the journalctl here

Hi Philip
The drive was online and available before I started the job. Its name is: WD5TBBackup2. I started the job and here is the result (please ignore the "Proxmox-Backups-QNAP" as that device is offline)

The moment I started the job the device became unavailable and I had to restart the VM with OVM to get access back...

after restarting the VM with OVM and starting the other job which contains several other LXC's it works... It is just the one LXC that has the issue... I guess file size might be the problem? ... This LXC uses 11.11 GiB) ... When I run the same job to an NFS share on my QNAP it all works... But I wonder why this is the case and how I could fix it

For now I am leaning more towards network issue. Do you just "see" the drive online or did you actually manage to use it?

Also lets digg deeper with sudo cat /etc/pve/storage.cfg lsblk and cat /etc/pve/qemu-server/<vmid>.conf
