Hello to all,
I have been battling this situation now for 3 days and still have not found a resolution. I appeal to any and all for help.
Here are the facts as far as I can tell.
- I moved a 66 node rocks based cluster to a diskless cluster using
the latest version of Centos and all updates in place. 2) users are added with home directory mounted across the nodes on the cluster so a user's home directory would sit on /export/home with sym link from home on head node 3) sshkey-gen used to create public/private key in .ssh so that user can have keyless access to all nodes, allowing sge jobs to run across nodes.
For my cluster, I have set it up this way:
- on the mater node, set up /etc/ssh/ssh_known_hosts so that it has a line for each node in the cluster, the key taken from /etc/ssh/ssh_host_rsa_key.pub
- copy master:/etc/ssh to each node in the cluster
- the new user script only adds the user to the master node and then pushes passwd and shadow and possibly group onto the other cluster nodes.
That's it. Hope that helps. Best regards. Robi
