Re: giant release osd down

What happened when you did the OSD prepare and activate steps?
Since your OSDs are either not running or can't communicate with the monitors, there should be some indication from those steps.

Hi All

I am new to ceph and I have been trying to configure 3 node ceph cluster with 1 monitor and 2 osd nodes. I have reinstall and recreated the cluster three teams and I ma stuck against the wall . My monitor is working as desired (I guess) but the status of the ods is down. I am following this link http://docs.ceph.com/docs/v0.80.5/install/manual-deployment/ for configuring the osd. The reason why I am not using ceph-deply is because I want to understand the technology. 

can someone please help e udnerstand what im doing wrong !! :-) !! 

Some useful diagnostic information 
ceph2:~$ ceph osd tree

-2      1               host ceph3
1       1                       osd.1   down    0
