Hi Everyone,

My sys had 2 disks 1 SSD 256 GB, and 1 HDD 1 TB,

I have installed proxmox on SSD, and mounted HDD(proxmox/Disks/Directory)


Even though my HDD have more space

Proxmox UI shows this
I followed this ->

How to Add a Storage Drive to Proxmox (works with Proxmox 7)​

is there any solution to this ?
you've choose "raw" vm disk , so allocated disk size is reserved.
you need use qcow2 to see "used" size.
or event better, a lvm-thin datastore.
First solution with qcow2 , you can move you raw vm disk to qcow2 format from hw option of the VM, Data will be cloned.

Second solution with lvm-thin , will require backup vm on another disk / format datastore disk then restore vm
thanks for reply gabriel, Would u please explain first solution in detail, I would like to proceed with that.
of course renaming do nothing.

screeshots are not required, we know the GUI.

Steps needed for your question is a good training and learning for beginners.
Try & See , We can't write a step by step for that.
Do backup on exernal disk if data is valuable , because wrong playing with storage can loss data.
