Upgrading Endeavour

Upgrading Endeavour nodes to Centos 6 started March 17, 2015 with node2:

Reboot Node2 from a USB key with Centos6 distribution installed. Chose "minimal install"
- Note: Should have added scp, i.e openssh-client stuff. Added this "by hand" by using from endeavour: cat openssh-client-... | ssh node2 "cat - > openssh-client.rpm" and then installing that rpm.
SSH into the system
Copy the Centos ISO to node2 with scp. Mount on /mnt/centos
Install packages with: yum --disablerepo \* --enablerepo c6-media install
List of old package installed are in ~root/new_packages.txt with the distribution and package version stripped already. From this list, the packages were filtered into "installed" and "available" with yum. From the resulting list of "available" only the x86_64 and noarch packages were installed.

Done

Initial installation of system
Update the ethernet configuration (eth0) to 10.0.0.2 and onboot=yes.
Install all previously installed packages
setup ssh for passwordless entry. See: http://itg.chem.indiana.edu/inc/wiki/software/openssh/189.html or http://en.wikibooks.org/wiki/OpenSSH/Cookbook/Host-based_Authentication
- Note: Endeavour identifies as master.farm.physics.unh.edu, and so this needs to be in the ssh_known_hosts file and in the shosts.equiv file and .shosts file.
Configure authentication: see SSSD
Synchronise clock with endeavour: rdate -s endeavour && hwclock --systohc
Configure automount: Frankly, it is a mystery why it works, since the setup seems incomplete, but hey, I won't complain.
Configure Infiniband
- See: http://pkg-ofed.alioth.debian.org/howto/infiniband-howto-4.html includes a number of tests. All passed.
- See: https://pkg-ofed.alioth.debian.org/howto/infiniband-howto-5.html -- tested OK.
- See: https://access.redhat.com/solutions/301643
- Note: The ib0 does not seem to come up automatically? Needs to be checked.
