Thanks a lot Joseph and Alistair… I have the following questions based on your inputs:
1)
Do I need to make changes to all the nodes or just the admin node? I guess all the nodes since ceph-deploy issues commands via ssh on all nodes… 2)
The installation guide recommends using
ceph user to communicate with other nodes. Do I login to the admin node as root user or
ceph user? From: alistair.whittle@xxxxxxxxxxxx [mailto:alistair.whittle@xxxxxxxxxxxx]
You also want to make sure that if you are using a proxy your proxy settings are maintained through sudo.
With my deployment I had to add a line to my sudoers file to specify that the https_proxy and http_proxy settings are maintained. Didn’t work otherwise. Defaults env_keep += "http_proxy https_proxy" From:

On Behalf Of Gruher, Joseph R If you are behind a proxy try configuring the wget proxy through /etc/wgetrc. I had a similar problem where I could complete wget commands manually but they would fail in ceph-deploy until I configured the wget
proxy in that manner. From:

On Behalf Of Trivedi, Narendra Hi All,
I am a newbie to ceph. I am installing ceph (dumpling release) using ceph-deploy (issued
from my admin node) on one monitor and two OSD nodes running CentOS 6.4 (64-bit) using followed instructions in the link below:
http://ceph.com/docs/master/start/quick-ceph-deploy/
My setup looks exactly like the diagram. I followed pre-flight instructions exacty as outlined in the link below:
http://ceph.com/docs/master/start/quick-start-preflight/
The ceph-deploy takes forever and then throws up the following error:

Interestingly, “wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm” on
each nodes (1 mon and 2 OSDs) succeeds without any problem. I have tried everything many times with root user, ceph user etc. but it fails every time! It is very frustrating!
Has anyone else experienced the same or similar problem?
Thanks a lot in advance! Nar
