[SOLVED] Proxmox Backup Server with disk full as a VM hosted on a PVE

[ZephOne]

Hello,
the context is that we have a Proxmox Virtual Environment hosted on a physical server.
This Proxmox Virtual Environment hosts only one virtual machine which is a Proxmox Backup System.
The VM which host the proxmox backup system has two disks, one for the OS from local-zfs of the hosting PVE, the other to store the datastore from a zfspool of the hosting PVE.
The second one is full which causes IO-error. The VM is not accessible through the console and is not online.
Is there a way to do some cleanings (remove old backup stored by the proxmox backup system VM, for instance) on the zpool via the Proxmox Virtual Environment ?

Is there free space in the zfspool pool?
Did you try to add more space to that second disk?
Which filesystem is used inside the VM for that disk?

Well actually we avoid the issue by wiping the VM disk and we are resyncing it using the primary datastore.
So no more issue.
