Re: [gpfsug-discuss] Using setfacl vs. mmputacl

I wrote such a tool about a decade ago. It is still around on any Scale node where the GUI is installed. Look for /usr/lpp/mmfs/gui/cli/chacl and lsacl respectively. Those command lines are technically unsupported, but since the ReST API is built on top of them you should be able to reproduce any bug via ReST (which is fully supported).
 
The ReST API itself is also a good choice whenever you want to automate changing of ACLs.

[...]  that you would do this over NFSv4 or Samba.[...]
 
I know this statement and I've been told the same many times for my projects I did...
I can't promise anything , nor am I able to rate .. if it is worth or not..
all I'm saying... I saw/see a need for setfacl directly on GPFS  in multiple projects..
 
so if that items is interesting for many people.. why not give it a try in 2021 ... knowing, that really developing such a tool is a lot of discussion and in the end it will most likely become a better "compromise"... But maybe this "compromise" could then be the very best solution we'll  ever get ..
 
P.S.
hey - at least the last 2 digit's of the year  has turned around ;-)  since you opened up this item
cheers

Well when I asked I was told by an IBM representative that it was by
design there was no proper way to set ACLs directly from Linux. The
expectation was that you would do this over NFSv4 or Samba.

So filing an RFE would be pointless under those conditions and I have
never bothered as a result. This was pre 2012 so IBM's outlook might
have changed in the meantime.
