hi All,

This is not OK, am I right? Is this a bug, or am I doing something wrong?
Lustre 1.6.4.3 on CentoS 5.2, client is 2.6.26+b1_8 on FC8.

$ getfacl .
# file: .
# owner: root
# group: root
user::rwx
group::r-x
mask::rwx
other::r-x
default:user::rwx
default:user:user:rwx
default:group::r-x
default:mask::rwx
default:other::r-x


$ mkdir 1
$ getfacl 1
# file: 1
# owner: root
# group: root
user::rwx
user:user:rwx            #effective:r-x
group::r-x
*mask::r-x*
other::r-x
default:user::rwx
default:user:user:rwx
default:group::r-x
default:mask::rwx
default:other::r-x

Why has it changed?


The same on ext3:

$ getfacl 1
# file: 1
# owner: root
# group: root
user::rwx
user:user:rwx            #effective:r-x
group::r-x
mask::r-x
other::r-x
default:user::rwx
default:user:user:rwx
default:group::r-x
default:mask::rwx
default:other::r-x

$ mkdir 1
$ getfacl 1
# file: 1
# owner: root
# group: root
user::rwx
user:user:rwx
group::r-x
mask::rwx
other::r-x
default:user::rwx
default:user:user:rwx
default:group::r-x
default:mask::rwx
default:other::r-x



 From this it's a bit offtopic. Maybe somebody can say, why is this on ext3.
So going forward on the above:

$ mkdir 1/2
$ mkdir -p 3/4
$ getfacl 1/2/
# file: 1/2
# owner: root
# group: root
user::rwx
user:user:rwx
group::r-x
mask::rwx
other::r-x
default:user::rwx
default:user:user:rwx
default:group::r-x
default:mask::rwx
default:other::r-x

$ getfacl 3  
# file: 3
# owner: root
# group: root
user::rwx
user:user:rwx            #effective:r-x
group::r-x
*mask::r-x*
other::r-x
default:user::rwx
default:user:user:rwx
default:group::r-x
default:mask::rwx
default:other::r-x


Why has it changed?

Thanks very much,
