Ceph OSD will not delete

[paradox55]

It refused to delete itself in the OSD list on proxmox. It's still "loaded" on the host node even after reboot.

I've also wiped/zapped the entire disk with gdisk and restarted.

Can't remove the OSD from /var/lib/ceph/osd because it's active.

...this is not the first time I've had this issue with Proxmox 6.

Ideas? I've already tried removing it from the tree/crush mapping via commands.

Error EBUSY: osd.4 is not `down`.

ceph osd down 4
ceph osd rm 4
ceph auth del osd.4

I have the same issue with the last osd. Stop doesn't work from GUI.
I could remove all osd from GUI but the last one didn't want to.
I tried after the commands and it was removed but in GUI won't disappear from the list and not able to select the disk when creating an osd.
Ceph complains about the osd existing in the crush map.
~# ceph osd crush remove osd.0 will fix it.

Same problem here on latest Proxmox
