Environment

Novell Open Enterprise Server (Linux based)

Situation

Need to remove a node from the cluster and then either reinstall it or reinstall it into a different cluster.

Resolution

Remove the node from the existing cluster.
  1. Do a "cluster leave" on the node you want to remove from the cluster.
  2. In iManager go to cluster options and delete the cluster server object that represents the node you wish to remove.
Clean up the old configuration
  1. Find out your current version of novell-cluster-services with"rpm -q novell-cluster-services" Make sure you know this version when it comes to reinstalling.
  2. Remove the novell-cluster-services rpm ie. (rpm -e novell-cluster-services-1.8.2.276-2)
  3. Delete all files in /etc/opt/novell/ncs
  4. Delete the /etc/sysconfig/NCS file

Reinstall into the existing or new cluster.
  1. Reinstall the novell-cluster-services rpm. If you have used the red carpet patch channel to update your server, then the most recent one will still be in your cache in /var/cache/rcd/patch_data or download it from download.novell.com/patch/finder. ie. (rpm -Uvh /var/cache/rcd/patch_data/novell-cluster-services-1.8.2.276-2.i586.rpm)
  2. Launch YaST or YaST2 and go to "Open Enterprise Server" and select "Novell Cluster Service (NCS)" then complete the installation.
