Here is how to add harddisk into proxmox storage pool.

1. After we connect new hard disk to our host. Verify attached harddisk in proxmox.

2. Format each harddisk. We will add sdb – sdf to our new storage pool.

root@proxmox:/# lsblk
NAME               MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda                  8:0    0 238.5G  0 disk 
├─sda1               8:1    0  1007K  0 part 
├─sda2               8:2    0   512M  0 part 
└─sda3               8:3    0   238G  0 part 
  ├─pve-swap       253:0    0     8G  0 lvm  [SWAP]
  ├─pve-root       253:1    0  59.3G  0 lvm  /
  ├─pve-data_tmeta 253:2    0   1.6G  0 lvm  
  │ └─pve-data     253:4    0 151.6G  0 lvm  
  └─pve-data_tdata 253:3    0 151.6G  0 lvm  
    └─pve-data     253:4    0 151.6G  0 lvm  
sdb                  8:16   0   1.8T  0 disk 
sdc                  8:32   0   1.8T  0 disk 
sdd                  8:48   0   1.8T  0 disk 
sde                  8:64   0   1.8T  0 disk 
sdf                  8:80   0   1.8T  0 disk 
root@proxmox:/#

Format each disk from sdb – sdf

root@proxmox:/# /sbin/fdisk /dev/sdb

Welcome to fdisk (util-linux 2.33.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Command (m for help): g
Created a new GPT disklabel (GUID: CF141939-59BA-2C40-AC12-75A379E67B22).

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

root@proxmox:/#

3. Create ZFS pool.

root@proxmox:/# /sbin/zpool create local-zfs /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf 
root@proxmox:/# /sbin/zpool status
  pool: local-zfs
 state: ONLINE
  scan: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        local-zfs   ONLINE       0     0     0
          sdb       ONLINE       0     0     0
          sdc       ONLINE       0     0     0
          sdd       ONLINE       0     0     0
          sde       ONLINE       0     0     0
          sdf       ONLINE       0     0     0

errors: No known data errors
root@proxmox:/#

4. Verify the pool is created.

5. Add the ZFS pool to proxmox. Go to Datacenter -> Storage -> add -> ZFS

Choose ZFS pool we created at step.3 then add

Verify our news storage is enabled and active. 🙂
