Hi In case you want to review with ls -l the POSIX permissions, please put the relevant permissions on the SMB share, and add CREATOROWNER & CREATETORGROUP. Than ls -l will show you the owner + group + everyone permissions.

That is you have zero visibility into what the hell it is doing when it all goes pear shaped unless you break out dtrace. I am not sure that using dtrace on a production service to find out what is going on is "best practice". It also in my experience stops you cleanly shutting down most of the time. The sooner it gets removed from the kernel the better IMHO. If you are using protocol nodes which is the only supported option as far as I am aware then that does not apply. I would imagined if you are rolling your own Ganesha NFS server it won't matter either. Checking the code of the FSAL in Ganesha shows functions for converting between GPFS ACL's and the ACL format as used by Ganesha. My understanding was one of the drivers for using Ganesha as an NFS server with GPFS was you can write a FSAL to do just that, in the same way as on Samba you load the vfs_gpfs module, unless you are into self flagellation I guess.
