Hello,

We have a PX node where the a compressed backup for the primary VM no longer fits in the defined zfs-backups storage areas (around 150g). A backup job fails at the end when it runs out of space. I have tried different compressions and types without success. At this moment, I am deleting some items from the VM to try and slim it down, but I have a question about the zfs-containers storage area.

It has been a while since we setup this PX node, but I believe we follow some standard suggested models with regard to allocating & sizing the various parts of the zpool. We had expected that some containers would be used on this node, but I don't believe that has happened. Nevertheless, the containers storage shows nearly 85% usage. I cannot find a defined container VM on the node anywhere.

I believe the VMs are just using vm-disks area for their hard drives and nothing else.

I am wondering if it is safe/OK/Possible to delete the zfs-containers storage and recreate a new, larger zfs-backups area with some of that space?

Hi,
could you share your /etc/pve/storage.cfg? What do the following commands show?
Code:
pvesm list zfs-containers
zfs -o space <dataset> -r
where <dataset> is the ZFS pool/dataset associated with your zfs-containers storage, i.e. the pool entry for zfs-containers in /etc/pve/storage.cfg.
