Why is space not being freed from disk after deleting a file?

[goldenfox]

I have a problem with (local-lvm) space in my proxmox. I deleted a lot of files to free up some space in (local-lvm), but the space in proxmox is still reserved.
In screenshot 01 in my (VM 100) I have 66g used from 147G and 75G is free, and I am using (local-lvm) for this VM. You can see that in screenshot 02.
And if I go to (local-lvm) to check the storage status, I see that 112.44G used from 151.64G so the free space is 151.64 - 112.44 = 39.2G.
How can I fix this problem? In a few weeks, (local-lvm) will be full and the VM will stop.

You have to set up discard for the virtual disk and set up discard for the guests filesystem or run fstrim regularily in each VMs guestOS.
For LXCs you need to run pct fstrim YourVMID regularily.

Please search the forum for "discard" and "fstrim". There should be hundreds of threads explaining this.
For the support of discard of virtual disks you need to go to the VMs hardware tab, edit the virtual disks and check the "discard" checkbox. You need to choose a protocol like "virtio SCSI" that supports TRIM commands or that checkbox will be grayed out.
How to enable discard/trim inside the VM totally depends on the guestOS and what filesystem the guestOS is using.
