CMU 7.1 - Cloning Issue



I'm taking CMU 7.1 for a test drive on a development server. I shook out most of the fuctionality already and everything seems to be working just fine... except for cloning. On a single compute node, I successfully kickstarted and backed up the node. However, when I try to clone it, I see the following in the cmucerbere log:


[1-Nov-2013_12:42:05] [CerbereDB] Locking node

... [repeats a lot]

Not really too sure where to begin troubleshooting. I am hoping that someone can help.

Re: CMU 7.1 - Cloning Issue

Sorry sorry! I saw this issue a long time ago. Has to do with the following sshd_config setting on the CMU server node:


#PubkeyAuthentication yes
PubkeyAuthentication no


Figured out a way to work around it. Problem solved.
