pve-moosefs

MooseFS on Proxmox.

Features

• Natively use MooseFS storage on Proxmox.
• Support for MooseFS clusters with passwords and subfolders
• Live migrate VMs between Proxmox hosts with the VMs living on MooseFS storage
• Cleanly unmounts MooseFS when removed

Future features

• Instant snapshots and rollbacks
• MooseFS block device (mfsbdev) support for high performance

DISCLAIMER

This is HIGHLY EXPERIMENTAL! I'm running it in production, but you should be careful.

Call it pre-alpha quality.

Do not use snapshots with your MooseFS storage, as they are actively being worked on and not ready yet

Usage

Adding as storage	Viewing a MooseFS storage target

Perform the following steps on your Proxmox host(s):

Easy:

• Upgrade to Proxmox 8.3.5
• Install the attached .deb file in Releases.

Harder:

• Upgrade to Proxmox 8.3.5
• Clone this Git repository and enter it with cd
• Make the Debian package: make
• Install the Debian package: dpkg -i *.deb

Graphical mounting

Now mount the storage! You can use the Proxmox GUI for this.

• Go to Datacenter -> Storage
• Click Add -> MooseFS and follow the wizard.

Command line mounting

Now mount the storage via command line: pvesm add moosefs moosefs-vm-storage --path /mnt/mfs

In this example, we create a custom storage called "moosefs-vm-storage" using the moosefs plugin we just installed.

You can apply the following optional settings:

• --mfsmaster mfsmaster.my.hostname - Set the mfsmaster IP or hostname to help MooseFS find the metadata server(s).
• --mfspassword mypasswordhere - If your MooseFS exports require a password to mount MooseFS, set this.
• --mfssubfolder media - If you need to use a folder within MooseFS instead of pointing at the root of the filesystem, set this.
• --mfsport 9421 - If you're running the mfsmaster on a custom port, you can set this. Note: Currently unused 🚧
