I would not mount a GPFS filesystem within a GPFS filesystem.
Technically it should work, but I’d expect it to cause surprises if ever
the lower filesystem experienced problems. Alone, a filesystem might
recover automatically by remounting. But if there’s another filesystem
mounted within, I expect it will be a problem..
Much better to use symlinks.
Think about that for a minute...
I guess if you are worried about /projects going away (which would
suggest something really bad has happened anyway) would be to mount the
GPFS file system that is currently holding /projects somewhere else and
then bind mount everything into /projects
At this point I would note that bind mounts are much better than
symlinks which suck for this sort of application.
