Proxmox VE ZFS Volume Setups

CLI Setup #

On a shell terminal execute the following (rename the zfs to your liking):

$ zpool create -f -o ashift=12 zfsa mirror /dev/sda /dev/sdb mirror /dev/sdc /dev/sdd
$ zfs list
$ zfs create -o mountpoint=/mnt/zfsa zfsa/mountpoint

GUI Setup #

Go to Proxmox VE → Datacenter → Storage → Add the zfsa ZPOOL as a ZFS Storage

Go to Proxmox VE → Datacenter → Storage → Add the /mnt/zfsa as a Directory

Important Tweaks (CLI) #

Mountpoint Options #

Edit the file /lib/systemd/system/pvestatd.service and add or modify the following line

After=pve-cluster.service zfs-mount.service

Set the following properties for the ZFS Mountpoints in /etc/pve/storage.cfg: Arguments in italics are deprecated or older.

• create-base-path 0
• is_mountpoint 1
• mkdir 0

Disabling ATIME #

If you do not have a specific case for which you’ll need to get the logged access times for a file, disabling atime in your zfs pool may improve performance.

zfs set atime=off zfsa

Create a new zpool #

To create a new pool, at least one disk is needed. The ashift should have the same sector-size (2 power of ashift) or larger as the underlying disk.

$ zpool create -f -o ashift=12 <pool> <device>

Create a new pool with RAID-0 #

Creating a ZFS Pool with RAID-0 requires a minimum of 2 Disks

$ zpool create -f -o ashift=12 <pool> <device1> <device2>

Create a new pool with RAID-1 #

Creating a ZFS Pool with RAID-1 requires a minimum of 2 Disks

$ zpool create -f -o ashift=12 <pool> mirror <device1> <device2>

Create a new pool with RAID-10 #

Creating a ZFS Pool with RAID-10 requires a minimum of 4 Disks

$ zpool create -f -o ashift=12 <pool> mirror <device1> <device2> mirror <device3> <device4>

Create a new pool with RAIDZ-1 #

Creating a ZFS Pool with RAIDZ-1 requires a minimum of 3 Disks

$ zpool create -f -o ashift=12 <pool> raidz1 <device1> <device2> <device3>

Create a new pool with RAIDZ-2 #

Creating a ZFS Pool with RAIDZ-2 requires a minimum of 4 Disks

$ zpool create -f -o ashift=12 <pool> raidz2 <device1> <device2> <device3> <device4>

Enabling Compression #

To activate compression use the following command in Command Line

$ zfs set compression=lz4 <pool>
