unable to restore a backup


Jan 27, 2021
I have a backup of a server that I am trying to restore. It fails with "ut of space" every time.

VM has 3 drives backed up to an SMB share (called "abc" )

I built another proxmox that I installed on a 240gb SSD.
I built a 2.1TB zfs pool with nothing on it (name="front").
I pointed to the "abc" smb share and chose the backup and tried to restore.

The server drives are 100gb, 300gb, and 800gb
The zst file is 250(ish)gb

My error is this:
restore vma archive: zstd -q -d -c /mnt/pve/abc/dump/vzdump-qemu-105-2023_09_16-16_00_08.vma.zst | vma extract -v -r /var/tmp/vzdumptmp58697.fifo - /var/tmp/vzdumptmp58697

Thinking that my /var/tmp folder is too small, I mounted a 3tb drive to the /var/tmp folder and it still fails.
BTW- it fails instantly, within 2-3 seconds.

What am I missing?
There are other, smaller VMs being backed up and I can restore those without problems, each of them are 200-300 gb each. Same "abc" location"

It looks like your zpool (front) is full.
To get a better overview of your configuration, please post your VM configuration and fs status.

zpool status
zfs list
tail -n +1 /etc/pve/storage.cfg /etc/pve/qemu-server/105.conf
