I used ceph-deploy to purge the data.
However it didn't remove LVM.
I'm gonna to see the "lvm" part.
Seems new, i used always disk instead since now.

Not sure if ceph-deploy has similar
functionality, but executing ‘ceph-volume lvm zap <device>
--destroy’ on target machine would have removed lvm mapping.

Sound strange that nobody knew this.
The issue is that data is purged but LVM partition are
leaved in place.
This means that you need to manually remove.
I just reinstalled the whole OS and on the data disks there
are still LVM partition named "ceph-*". These partition are
ACTIVE by default.
To get rid of the old data:
#find disks
lsblk
See in the result all the "ceph-*" volume groups and remove
theme:
vgchange -a n ceph-XXXXXXXXXXXXXXXXXX
vgremove ceph-XXXXXXXXXXXXXXXXXXX
Do it for all disks.
Now you can run ceph-deploy osd create correctly
without being prompted that disk is in use.

Hi
everybody,
I would like to start from zero.
However last time I run the command to purge everything I
got an issue.
I had a complete cleaned up system as expected, but disk was
still OSD and the new installation refused to overwrite disk
in use.
The only way to make it work was manually format the disks
with fdisk and zap again with ceph later.
Is there something I shoulded do before purge everything in
order to do not have similar issue?
Thanks,
Max
