[gpfsug-discuss] Using setfacl vs. mmputacl

[Losen, Stephen C (scl)]

Hi folks,
Experimenting with POSIX ACLs on GPFS 4.2 and noticed that the Linux command setfacl clears "c" permissions that were set with mmputacl. So if I have this:

...
group:group1:rwxc
mask::rwxc
...

and I modify a different entry with:

setfacl -m group:group2:r-x dirname

then the "c" permissions above get cleared and I end up with
...
group:group1:rwx-
mask::rwx-
...

I discovered that chmod does not clear the "c" mode. Is there any filesystem option to change this behavior to leave "c" modes in place?
