  • How can I prevent my RHEL cluster service from failing during relocation if it cannot unmount a filesystem resource?
  • A service is up and running with 1 or more mounted file systems. Some user has left a session open that is cd'd into that file system structure. When I manually migrate the service it fails as the filesystem being accessed cannot unmounted.
  • clusvcadm -r <service> -m <node> failed.
  • A cluster service containing an fs resource failed while stopping or relocating:

    node1 clurgmgrd: [8584]: <err> 'umount <mount point>' failed, error=0
