Migration to a new torque server

Reconfiguring wn-c cluster

Preparation

1. Make sure a common ssh_known_hosts file exists with all wnc and wnb keys + service nodes (see torque.hep.kbfi.ee:root/keys for an example of a script).
2. Assure (just in case) that no local user .ssh/known_ssh_hosts file exist.
3. Make sure that /etc/ssh/shosts.equiv contains all wn names at europa and torque.
4. Make sure that /etc/hosts contains correct entries on all of the nodes (use wnb/europa as an example). We support fqdn of the nodes in the form of <node name>.local

Migration

1. Add node to a new torque:

 qmgr -c 'c n wn-c-##.local'
 qmgr -c 's n wn-c-##.local np=24'

1. On a node: run migration script: /opt/software/shared/wnb/<smth with a mig in its name>.sh
