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
# id weight type name up/down reweight
-1 2 root default
-3 1 host ceph2
0 1 osd.0 down 0
-2 1 host ceph3
1 1 osd.1 down 0
