Hi all,
On my test cluster I have 3 MON, 2 MDS and 2 OSD. I'm doing some
failover test on OSD and got a strange thing on the status.
The 2 nodes hosting the OSDs have been shutdown but the status continu
to 'see' one alive :
# ceph -v
ceph version 0.29 (commit:8e69c39f69936e2912a887247c6e268d1c9059ed)

How could it be, is it a bug ?
(be sure I triple checked that my 2 osd nodes are really shutdown)
Thanks !
