Documentation on activating an osd on a new node with cephadm

Hi,

Maybe this is already here on the list but I couldn't find it. These are the steps I had to take to move an osd to a new host (cephadm/pacific 16.2.5):

  *   physically move the disk to the new host (the host may be lost)
  *   (new host) cephadm ceph-volume lvm list (to find osd id (name/number) and osd fsid)
  *   (new host) mkdir /var/lib/ceph-$cluster-id/osd.$osd-id
  *   create minimal config (or copy from other osd) and put it in a file config in the new directory
  *   get auth-key for the osd and put it in a file keyring in the new directory
  *   cephadm --image $ceph image (if local registry) deploy --fsid $cluster-id --name osd.$osd-id --osd-fsid $osd-fsid

It seems it has been corrected in 16.2.8, but still thought I could share.

Thanks!
