Probably the most interesting new feature in Proxmox 9 (Beta 1):
Finally we're able to create #Snapshots of VMs with shared block storage (such like #iSCSI, #FibreChannel & #NVMeoF) with LVM Thick without doing dirty workarounds. Well done Proxmox (& Alex!).
Recently, I created a plugin (including PVE UI integration) for #NetApp based storages to create storage side snapshots.
PS: #ProxLB also already supports PVE9!
