Hi
I have installed a new proxmox server and when i try to create a ZFS or LVM it says "No Disk Unused" in devices list.

These information are shown in my disk details from Proxmox web gui
Enabled: Yes
Active: Yes
Content : Disk image, ISO image, Container, Snippets, Container template
Type: Directory
Usage: 0.45% (2.07 GiB of 456.55 GiB)
I have two SSDs attached to server. but it is displaying only and and this one is also not available to use.
When i create a VM. No disk is attached to VM as well.

I want to attach both disks to PROXMOX and make them available for use.
__________________________________
I have two SSDs available but it says nothing available. why? and what should i do to make it available. Google searches show FDISK partition removal but it corrupts my server and i have to install it again if i do so.
 
Please post the output of the following two commands
Code:
fdisk -l
Code:
pvesm status


"Unused" means really empty. If you have 2 disks in total and PVE is installed then at least one certainly is not empty.
When i create a VM. No disk is attached to VM as well.
This is something you have to specify when creating the VM. Your directory storage should be available.
 
Directory is available. Both of the disks show in disks list. but why am not i able to create LVM with them? and they don`t show in Disks list when installing Windows in VM
Creating LVM says No Unsed Disks.
I swear both of those disks have nothing other than proxmox installed on one of them.

Is this at some hosting provider or did you install this on your own physical server via ISO?

In your fdisk output you can see entries on /dev/sda as well as /dev/sdb. Consequently, no disk is unused. The reason for this is that your two SSDs form a RAID (which is also stated in the fdisk output).

and they don`t show in Disks list when installing Windows in VM
This is a different topic. Without changing to much on your current setup, you have to to click on your VM -> Hardware -> Add Hard Disk. There you choose your directory storage "local" for the virtual disk to reside on. This virtual disk is then passed to your VM.
 
Problem solved. Rebooted in rescue mode and used

Delete PARTITION TO free up space
use cfdisk to delete

Use fdisk -l to see partitions
enter fdisk /dev/sdb to start editing sdb

create new partition using n and enter size
enter w to write
enter cltr+c
reboot


Free up DISK
dd if=/dev/zero bs=1k count=10 of=/dev/sdb3

Extend a disk
vgextend vg_data /dev/sdb3

If you want to use sda for ZFS you need to delete all data on it. Delete the 9 partitions.
 
Can I delete the data from UI ?
if not can you please let me know how we can do that via commandline?
 
You can for example use fdisk using CLI.

fdisk /dev/sda
And then use fdisk to delete the partition (I think it was entering "d" to delete the last partition) and writing changes to the disk (I think it was "w") to finish it. If you got 9 partitions you need to enter "d" 9 times.
