I have an RFE for this :

<https://ideas.ibm.com/ideas/GPFS-I-986>
At this point in time requests for being able to recursively set NFSv4
ACL's on GPFS are over 12 years old. At least that would be about the
time frame for requests for the feature made by myself.
Unfortunately I think the chances of IBM doing anything about it is
somewhere around ħ
Shame really as it would not be particularly hard to do. I have an old
proof of concept that uses the FreeBSD tool (mainly of licensing
reasons). Basically it transforms the GPFS ACL to the storage format
used by the FreeBSD tool. Just needs refactoring to use the GPFS ACL
storage format throughout. Probably about a weeks developer effort.
There are some poorly publicly documented features of the GPFS ACL
format that make me reluctant to release my code in case it chews
someone's filesystem.
Looks like IBM might have actually delivered it as a feature

In summary
The version of chmod linked below fully supports the manipulation of
NFSv4 ACLs. This is the version that Isilon OneFS uses and it's
fantastic. I can add/remove Active Directory users and groups, modify
permissions, add ACL control flags, etc., all without ever touching a
Windows computer.

Can this work on GPFS?
It is marked as delivered in Scale 5.1.7 in September of last year.
Though I have not the foggiest how you use it and can't find any mention
in the command reference for 5.1.9
