How to add the remaining storage?

[tkalfaoglu]

Hi I have a server with two 950GB SSD drives.
I installed ProxMox using the easy way and it shows that it has two 400GB storage areas; vm-100-disk-0 and vm-101-disk-0. both 400GB in size.

So I'm missing about half of the storage. Here is what it looks like:

# lsblk -o name,size,fstype

So how can I add the remaining storage to the system?
Many thanks, -turgut

You have a thin provisioned LVM pool that uses one of the two NVMe drives. In this pool you have two VM images.
The other space on that NVMe is used by the Proxmox installation.

The thin pool is filled to 50.82% because one VM image already uses 99.99% of its 400GB size but the other only 3.7%.

You can still create more images in that pool as long as the actual usage does not exceed the real size of 816GB.

On the other NVMe there are two XFS filesystems that have nothing to do with Proxmox. Looks like it contains a CentOS installation.

Ah! Wonderful, the other one must have been lingering from my previous installation. I had assumed it would format both drives.
Many thanks!

you are not going to believe this but chatgpt fixed it ! I explained it the problem , it was asked me the output of some commands and it recommended which commands to type . some didn't go thru and it offered new commands , and after about 5 minutes it fixed my issue !
I was scared to trust it , but I was never good with lvm and my proxmox is a new setup without too much critical data so I said what the heck .

I'm still amazed at how far ai has come !
