Subject: ceph-volume: when reusing an osd ID you must give that id to 'osd new'
X-Git-Tag: v13.0.2~387^2~2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=43f699fcbc9f30875f70295e086a4e423008b266;p=ceph.git

ceph-volume: when reusing an osd ID you must give that id to 'osd new'

If you do not then auth will not be created for the new OSD and the
daemon will not be able to start.
