1)
Check your /etc/filesystem on EACH node . Is the mount order correct on
all cluster nodes ?

2)
Check with
$ mmlsmgr
the system manager for a FS.

Its bad if node A mounts /s01 and node B mounts /s01/app

3)
Maybe you are runing in a timing issue. Meaning that /s01/app will be
mounted before /s01 - i do not know if GPFS 2.x ( x=>2) can asyncronly
mount.

4)
Do not use nested GPFS mount when possible. Just create a Subdirectory
for GPFS mounts like:

/cls

and mount there all GPFS FS

5)
Do not use automatic mount at all.
