ProxMox 7.0 catch - Ceph OSD destroy: No Disks unused

ProxMox OSD create: No Disks unused

I just realized that when I destroy Ceph OSD in ProxMox 7.0-11 - either in Web UI or using console

# pveceph osd destroy X --cleanup 1

I can't create new OSD on the same disk. ProxMox simply says that there are "No Disks unused" in the Web UI OSD create form. And in console I get:

# pveceph osd create /dev/sdX
device '/dev/sdX' is already in use

Zaping disk with the customary

# ceph-volume lvm zap /dev/sdX --destroy

does not help, even though it is often very useful command.

Workaround

First I realized that rebooting the machine helps. But... Rebooting hyperconverged hypervisor to see the perfectly working disk drive in self-healing unbreakable unstoppable storage? In 2021? Seriously??? I realized that a bucnch of crazy Perl libraries that do everything in ProxMox call this command:

# lsblk --json -o path,parttype,fstype
{
   "blockdevices": [
...
      {"path":"/dev/sdX", "parttype":null, "fstype":"LVM2_member"},
...

and they consider everything with fstype other than null to be "used". The solution is to create any partition table on the /dev/sdX. For example just running

# fdisk /dev/sdX

and pressing "w" to save empty table is enough for the disk to re-appear.
