Hello Fellow Members,

I am new to this and I have installed proxmox on a 2TB SSD .

Bash:
NAME               MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
nvme0n1            259:0    0  1.8T  0 disk
├─nvme0n1p1        259:1    0 1007K  0 part
├─nvme0n1p2        259:2    0    1G  0 part /boot/efi
└─nvme0n1p3        259:3    0  1.8T  0 part
  ├─pve-swap       252:0    0    8G  0 lvm  [SWAP]
  ├─pve-root       252:1    0   96G  0 lvm  /
  ├─pve-data_tmeta 252:2    0 15.9G  0 lvm 
  │ └─pve-data     252:4    0  1.7T  0 lvm 
  └─pve-data_tdata 252:3    0  1.7T  0 lvm 
    └─pve-data     252:4    0  1.7T  0 lvm

Now I want to partition the 96GB so that I can allocate for VM. I am not planning to setup a separate RAID anytime soon .
I am looking to partition the drive such that I allocate not more than 256GB to the proxmox OS and remaining can be used for data storage .
Kindly suggest where can I start .

Thank you .
 
That isn't what you want to do.

You see that 1.7 TB "pve-data" thingy? That should show up in the gui as "local-lvm" or similar. That is where your VMs will go. Just set that as the storage when you create a VM. Then read the storage section of the manual.
Thanks Bobh , but what I am confused with is the Proxmox OS sitting without any partition of disks .
Is that not a problem ?

Again, I advise to read the manual. You have what's called an LVM-thin setup.

The installer set up the Logical Volume Manager, which is different from traditional partitions. It manages a chunk of disk space by carving it up into virtual block devices "on demand". When you make a VM a virtual block device will be created in the pve-data area to hold the VM disk. This is more efficient that storing the disks as files on a regular filesystem.

The PVE OS lives on the 96 GB "pve-root" area, which is a virtual disk within the LVM space. The kernel is stored in the small /boot partition so that the boot loader can find it, but the main OS is a logical volume within the LVM managed area. The VM's are not going to be stored on the root partition, they will be managed by the LVM in that 1.7 TB space.

This is all explained in the PVE manual, which is linked at the top of the web GUI. There are also many tutorials about the Linux Logical Volume Manager out there that explain this as well.
