[one-users] Starting Ceph OSD

[Pons]

Hi All,
We monitored two of our osd as down using the ceph osd tree
command. We tried starting it using the following commands but ceph osd
tree command still reports it as down. Please see below for the commands
used. 

command:sudo start ceph-osd id=osd.0
output: ceph-osd
(ceph/osd.0) stop/pre-start, process 3831

ceph osd tree output:
# id
weight type name up/down reweight
-1 5.13 root default
-2 1.71 host
ceph-node1
0 0.8 osd.0 down 0 
2 0.91 osd.2 down 0 
-3 1.71 host
ceph-node2

command: sudo start ceph-osd id=0
output: ceph-osd (ceph/0)
start/running, process 3887

ceph osd tree output:
# id weight type name
up/down reweight
-1 5.13 root default
-2 1.71 host ceph-node1
0 0.8
osd.0 down 0 
2 0.91 osd.2 down 0 
-3 1.71 host ceph-node2

command:
sudo start ceph-osd id=0
output: ceph-osd (ceph/0) start/running,
process 4348

ceph osd tree output:
# id weight type name up/down
reweight
-1 5.22 root default
-2 1.8 host ceph-node1
0 0.8 osd.0 down 0

2 0.91 osd.2 down 0 

Is there any other ways to start an OSD? I'm out
of ideas. What we do is we execute the ceph-deploy activate command to
make an OSD as UP. Is that the right way to do it? We are using ceph
version 0.80.4 

Thanks!

Regards,
Pons
