Do I need to make changes to my GFS/GFS2 file systems when renaming the cluster in RHEL?

Issue

• Need to change the name of a pre-existing cluster that has associated GFS or GFS2 file-system(s)
• Changing A GFS2 locktable Name
• What changes should be done to a gfs2 filesystem after changing the cluster name ?

• After changing <cluster name> attribute in /etc/cluster/cluster.conf, GFS or GFS2 file system fails to mount:

  # mount -t gfs2 /dev/clust/lv1  /mnt/lv1
  fs is for a different cluster
  error mounting lockproto lock_dlm
