Context: GlusterFS storage support was dropped from PVE9. While it can be worked around with the "Directory" storage, having a plugin offers a lot of convenience. Furthermore, GlusterFS can offer significantly improved performance for non-enterprise hardware (see https://forum.proxmox.com/threads/glusterfs-is-still-maintained-please-dont-drop-support.168804/)
Instructions: Install glusterfs-client and copy to /usr/share/perl5/PVE/Storage/Custom
