HI ,
those so called "nested" mounts .. you need to make sure to have the "upper" FS mounted first
this here may help
- --mount-priority Priority
- Controls the order in which the individual file systems are mounted at daemon startup or when one of the all keywords is specified on the mmmount command.
File systems with higher Priority numbers are mounted after file systems with lower numbers. File systems that do not have mount priorities are mounted last. A value of zero indicates no priority.
in addition , now to your question: you try to umount the gpfs2 locally on gpfsgui, and it seems, it is not mounted...
this does not mean.. that the file system is not mounted any where else .. .So before you initiate the mmchfs -T .... you should make sure, to have umounted it "everywhere
use mmlsmount <dev> -L to navigate ...
