Thin Provisioning shrink size

[cm350]

Hi Guys,

On our own proxmox server we have the issue that our local-lvm (ssd-raid) is almost full.

We have a lvm-thin storage disk. We use raw files for the virtual machines and mostly VIRTIO (for the windows) and IDE for the debians.

We moved a lot of data out of the virtual machines in to the cloud etc...
But the space we cleared is not showing up on the disks in proxmox. So how do we free up this freed-up space?

Hi,

you must run fstrim in the VM, that works you have to activate the discard option on the VM Disk in the Hardware tab.
IDE does not support the discard option.
