No Space

ood night, I use the Proxmox VE in a laboratory for studies.

I have 2 discs:
* 1 SATA 6GBps 7200RPM 1TB HD
* 1 6GB SATA 480GB SSD

- HD is used only for software and files
- The SSD I use only for the VM's systems

The HD is 100% busy and that's correct because I have allocated it all to a single disk

I needed space on the SSD for a new VM so exclude a VM that I no longer used.

Look at the problem, the space didn't come back despite having deleted the VM. How do I clean data from previous VM's?

Before the update there was no PURGE option when trying to delete a VM, is this option related?

Thank you very much, I count on your help.
