Hello everyone, I want to share my experience dealing with a backup issue on my Proxmox server.

I had a scheduled backup job, but the NFS storage I used had a network issue. This caused my backup to run for around 20 hours just for a 100GB thin-provisioned VM — even though the actual data inside the VM was less than 20GB.

To solve this issue, I went to the shell and unmounted the NFS storage using the following command:

Then, I unlocked the VM with this command:

After that, the VM started working again.

Thanks!
I hope this helps anyone who faces a similar issue.

Bash:
umount -f /mnt/pve/[mynfs-storage]

Then, I unlocked the VM with this command:
Bash:
qm unlock [vmid]

After that, the VM started working again.

Thanks!
