[PVE 6] Add proxmox storage.

14 Oct
October 14, 2019

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. 🙂

This problem occurred because we are free user without proxmox enterprise subscription and this prevent us from update or install new package. Here’s how to fix it.

1. Comment out proxmox enterprise source.

root@proxmox:/# vim /etc/apt/sources.list.d/pve-enterprise.list
#deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise

2. Add new proxmox source. Delete old one and put in new source.

root@proxmox:/# vim /etc/apt/sources.list
deb http://ftp.debian.org/debian buster main contrib
deb http://ftp.debian.org/debian buster-updates main contrib

# PVE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pve buster pve-no-subscription

# security updates
deb http://security.debian.org buster/updates main contrib

3. Update new source list.

root@proxmox:/# apt-get update

Change default port in proxmox

There is no direct method to change default port in proxmox so we use iptables to redirect to desire port instead.

1. Find network interface to apply iptables rule in proxmox. In this case VM bridge 0 is the interface we should apply our iptables rule.

root@proxmox:/# more /etc/network/interfaces
auto lo
iface lo inet loopback

iface enp5s0 inet manual

auto vmbr0
iface vmbr0 inet static
	address 192.168.1.5
	netmask 255.255.255.0
	gateway 192.168.1.1
	bridge_ports enp5s0
	bridge_stp off
	bridge_fd 0

iface eno1 inet manual

iface wlp0s20u4 inet manual
root@proxmox:/#

2. Apply iptables rule to incoming network interface. We will change proxmox default port 8006 to 41568.

root@proxmox:/#iptables -t nat -I PREROUTING -i vmbr0 --dst 192.168.1.5  -p tcp --dport 41568 -j REDIRECT --to-ports 8006

3. Save iptables rules.

root@proxmox:/#apt-get install iptables-persistent
root@proxmox:/#/usr/sbin/netfilter-persistent save
