Hello,
We have configured 'Directory' storage having SAN as backing storage, the SAN
storage is mounted at file system path (/mnt/pve/SAN-Storage1) with type ext4.
We have couple of VMs running on this storage. When we try to create a
persistent bitmap on qcow2 file then that fails with below error. The disk at
'scsi0' is "scsi0: SAN-Storage1:101/vm-101-disk-1.qcow2,iothread=1,size=32G".
So, the question here is, why are we getting error to create persistent bitmap
for qcow2 disk?

{"node":"drive-scsi0","name":"bm_1","persistent":true}}' | socat -

{"error": {"class": "GenericError", "desc": "Can't store persistent bitmaps to
