Why do I get "fs is for a different cluster" when I attempt to mount a GFS or GFS2 filesystem?
Issue
- How do I change the name of my gfs/gfs2 filesystem?
- Why do I get this error when trying to mount my gfs/gfs2 filesystem?
# mount -t gfs2 /dev/clust/lv1 /mnt/lv1
fs is for a different cluster
error mounting lockproto lock_dlm
- I get this error in the logs when trying to mount a gfs/gfs2 filesystem:
gfs_controld join: fs requires cluster="GFSPRD" current="gfsprd"
RHEL7 logs would look similar to
