It’s not just the nfs4_setfacl tool. Also cp and rsync will fail to cooy

I have an RFE for this :

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.
