Description :
An xfs filesystem was backed up daily via xfsdump. The mount point of the 
filesystem was changed, and xfsdump was called to back up the filesystem
with the new mount point. When xfsdump -I was called using the NEW
filesystem mount point, it failed to retrieve any information, and in fact gave 
this:
xfsdump:INV:open failed on mount point "efs:/groups/ulib"

If you run xfsdump -I with mnt= the ORIGINAL mount point, you can see
the entry for the NEW mount point.
