Hi,
After being forced to reinstall the O/S on all my Ceph nodes, I'm trying to
reactivate the OSDs, whose data lie on separate drives. The OSDs are
recognised:
mixtile@blade3n3:~$ sudo sudo ceph-volume lvm list
[sudo] password for mixtile:
====== osd.1 =======
[block]
/dev/ceph-5b8338a0-9246-48f5-9cfd-e1bbfa1cc199/osd-block-ccba3dd

*But: *When trying to link the OSD to the all-new Ceph installation (I've
made several Google searches with contradictory results. This is the last
one.), I get an error:
mixtile@blade3n3:~$ sudo cephadm shell

This puzzles me because I'm already root, but the Bluestore tool won't let
me reactivate the OSD? The old OSD is now full of valuable production data.
And: Isn't it possible to use ceph orch to perform this operation?
