Ceph - how to add back OSD that was removed from cluster by mistake, but the partitions are untouched - data still exists there

Solution Verified - Updated -


The OSDs were purged by mistake:

# ceph osd purge {id} --yes-i-really-mean-it

OR following commands were executed against OSDs:

# ceph osd crush remove osd.{id}
# ceph auth del osd.{id}

But the OSD partitions are remaining untouched - no data was removed from the OSD disk devices.
