You need to stop all daemons, remove the mon stores and wipe the OSDs with ceph-volume. Find out which OSDs were running on which host (ceph-volume inventory DEVICE) and use
ceph-volume lvm zap --destroy --osd-id ID
on these hosts.

Hello team,
I have deployed ceph cluster in production , the cluster composed by two
types of disks HDD and SSD , and the cluster was deployed using
ceph-ansible , unfortunately after deployment the HDD disks appear only
without SSD , would like to restart deployment from scratch , but I miss
the way on how to erase disk to the initial state . try to format disks but
LVM comeback with disks.
