ZFS Disk Usage

[jcbhltz22]

Hello,

I am running Proxmox with a mirrored ZFS array and am running out of space.

Deleting files on the VM does not free up space on the host ZFS array, is there something I can do to reduce the size used? I deleted over 1TB of files and the array still shows the same 10.5TB used (92%).

Thanks!

Snapshots!

zfs list -o space
USEBYSNAP = snapshots

zfs list -t snapshot

EDIT:
That is one possibility.

VMs however use ZVOL object storage instead of files. They can be resized as well. The problem is that the VM has to be able to deal with it as well.
I have no experience with changing sizes of ZVOLs, maybe sombody else can jump in.
