pve5 couldn't create ceph osd with btrfs filestore

[hrens]

pve-manager version: 5.2-7
When I try to create ceph osd with btrfs filestore, I got an error:

pveceph createosd /dev/sdf --bluestore=0 --fstype=btrfs
create OSD on /dev/sdf (btrfs)
Creating new GPT entries.

I've try to execute this command manually and got an error message:

Is there any solution, how to create create ceph osd with btrfs filestore ?
It was works fine on earlier pve4.
