Overview

This guide shows you how to create a Storage in Virtualizor. This is supported in versions 2.6.6+ only.
You can define multiple storage per physical node.

Note: Space gets synced on panel once you go to create vps page.
You can add multiple storages on panel with different storage type on panel except for Openvz and Openvz 7.
Cloning and template creation will depend on the storage type used by the vps.

Add / Define Storage

To add a new storage go to the Virtualizor Admin Panel -> Storage -> Add Storage.
Following is a screenshot :

LVM Based Storage

Create Storage

This example creates an LVM logical volume called new_logical_volume that consists of the disks at /dev/sda1, /dev/sdb1, and /dev/sdc1.
⁠ Step 1: Creating the Physical Volumes To use disks in a volume group, you label them as LVM physical volumes.

Warning :This command destroys any data on /dev/sda1, /dev/sdb1, and /dev/sdc1.

root> pvcreate /dev/sda1 /dev/sdb1 /dev/sdc1
  Physical volume "/dev/sda1" successfully created
  Physical volume "/dev/sdb1" successfully created
  Physical volume "/dev/sdc1" successfully created

⁠ Step 2: Creating the Volume Group The following command creates the volume group vg1.

root> vgcreate vg1 /dev/sda1 /dev/sdb1 /dev/sdc1
  Volume group "vg1" successfully created

You can use the vgs command to display the attributes of the new volume group.

root> vgs
  VG            #PV #LV #SN Attr   VSize  VFree
  vg1             3   0   0 wz--n- 51.45G 51.45G

Note: The VFree size shown in the vgs command will be used for creating VMs, so please make sure the size is always greater than zero.

Add Storage

After creating the Storage you will need to add it on Virtualizor panel.
Storage Type : Storage type should be LVM.
Path : In case of LVM please specify the Volume Group path /dev/VG_NAME.

File Based Storage (RAW/QCOW2)

Create Storage

You will need to create the storage before adding it in Virtualizor.
You will just need to create a folder on the target node :

root> mkdir /vms # You can create any path as per your choice.

Add Storage

After creating the Storage you will need to add it on Virtualizor panel.
Storage Type : Storage type should be File.
Path : Path should be the full name of the directory created in the previous step (/vms in this case) to store VMs disk.
File Format : You can choose the Format as RAW or QCOW2 for File based storage.RAW has better performance but no overselling where as QCOW2 supports overselling of Disk Space.

ZFS Storage

Virtualizor supports ZFS Storage.
You can follow the guide in the link below for configuring and adding ZFS Storage in Virtualizor.

Thin LVM Based Storage

Thin LVM allows you to create thin provisioned disks for your VMs.

Create Storage

You will need to create a Thin Pool on the main node from an already existing Volume gorup.
In the following example we will be creating a thin pool of size 100GB in the Volume group "MyVolumeGroup".
You will just need to create a folder on the target node :

root> lvcreate --size 100G --type thin-pool --thinpool thin_pool MyVolumeGroup

Add Storage

After creating the Storage you will need to add it on Virtualizor panel.

Storage Type : Storage type should be Thin LVM.
Path : Path should be the full path of the thin pool /dev/VGName/THINPOOLNAME.If we consider the above example then the path will be "/dev/MyVolumeGroup/thin_pool".

Ceph Block Storage

Create Storage

Follow the below guide to create ceph storage cluster:

https://docs.ceph.com/en/octopus/install/ceph-deploy/quick-ceph-deploy

To create ceph block device refer to below guide:

https://docs.ceph.com/en/latest/start/quick-rbd/

Add Storage

After creating ceph block you will need to add it on Virtualizor panel.

Storage Type : Storage type should be Ceph Block Device.
Ceph Pool Name : Ceph Pool Name should be the ceph block device configured on the ceph cluster example "rbd".

Ceph File System

Create Storage

Follow the below guide to create ceph storage cluster:

https://docs.ceph.com/en/octopus/install/ceph-deploy/quick-ceph-deploy

To create file system refer to below guide:

https://docs.ceph.com/en/latest/cephfs/createfs/

To mount file system with kernel driver refer to below guide:

https://docs.ceph.com/en/latest/cephfs/mount-using-kernel-driver/

Add Storage

After creating ceph file system you will need to add the mount path in Virtualizor panel.

Storage Type : Storage type should be File.
Path : Path should be absolute path on which the ceph file system is mount example "/home/cephFile".
