Proxmox Followup: Block Storage

Now that you have successfully converted Debian 9 to Proxmox, this guide will assist you in adding additional storage space. Having this storage will assist in HA & live migrations, should you have a cluster setup. 

Creating & Attaching Storage Volume

Creating a storage volume is done within the project where the Proxmox device resides. You can find that at the top of the portal. 


When creating a volume you have the choice between standard or performance:

Standard: [$ 0.000104/GB per hour]

  • 500 IOPS per volume. 
  • Good for backups and general use cases

Performance:  [$ 0.000223/GB per hour]

  • 15,000 IOPS per volume
  • Excellent for I/O heavy workloads

With the volume created you will need to manage the device to connect the volume  to the appropriate device. 


After selecting the device and saving the volume attachment, you must run the packet-block-storage-attach script CLI (command line, within the device). The command must be run as root user or a wheel user with sudo access.

$ packet-block-storage-attach

portal: iqn:

  `- 3:0:0:0 sdc 8:32 undef ready running
Block device /dev/mapper/volume-8bc499e7 is available for use

   ️Please Note: Multipath is not enabled by default on Proxmox, please see this guide to set that up. 

Adding Storage through Proxmox UI

Adding the newly created storage volume to the Proxmox install is done in three steps: Datacenter → Storage → iSCSI


Continue the process on the popup window requesting information about the volume you are attaching: 

  • ID: the name for your storage mount point
  • Portal: the IQN which is the 10.x IP address from the packet-block-storage-attach command you previously ran. 
  • Target: once a valid 10.x IP address is adjusted you should see see a target in which you can select. 


Upon completion your storage volume appears on the top under the primary storage screen 


To utilize the newly added block storage volume, you must create another storage mount point, this time LVM. 


The next screen prompts you for items required to complete this storage LVM. 

  • ID: a name you wish to call your this volume, it will contain the virtual machine disks & container images. 
  • Base Storage: is the iSCSI you previously added 
  • Base Volume: is as shown, and the only option
  • Volume Group: a name in which you want to call the storage group. 
  • Content: You can have one or both, VM disk images / container images.


You should now see both the iSCSI and LVM listed under storage


Bravo! You now have a working block storage volume to expand your existing space for your containers / virtual machines.
