I solved by myself.
I' writing here my findings to save some working hours to others.
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
