Hum some strange options on your share there for a GPFS file system. I 
would personally kill the following options

         inherit acls            = no
         inherit owner           = yes
         inherit permissions     = yes
         nt acl support          = yes

And just use NFSv4 ACL's in the file system with

	ea support = yes
	store dos attributes = yes
	map readonly = no
	map archive = no
	map system = no
	map hidden = no

Something like this is also required to make it work safely and properly.

         gpfs : sharemodes = yes
         gpfs : winattr = yes
         force unknown acl user = yes
         nfs4 : mode = special
         nfs4 : chown = no
         nfs4 : acedup = merge

Note having the gpfs : sharemodes as no is really a bad idea, as even 
local access to a file can muck things up.

I would have also thought that having the fileid vfs module loaded is a 
good idea on a GPFS based Samba server.
