fuse_setxattr() permits setting security.XXX only if selinux is
enabled. The command succeeds if the volume is fuse-mounted the
following way:
#glusterfs --volfile-server=<server IP> --volfile-id=<vol name>
--selinux <mount point>
Good catch ! Thanks Ravi.
I am not sure how to enable selinux when mounting a gluster volume via
nfs.
Gluster NFS which is of version 3 (As per NFSv3 protocol spec) does not
support extended attributes. So it is N/A for NFS. :)
Thanks,

hi Diego,
I tried the operation on my machine and it is failing with operation
not supported, both on the bricks and mount. Could you please give
the output of the execution on your machines & gluster mount point.
Brick:
09:49:17 :) ⚡ touch testfile && setfattr -n security.NTACL -v foo
testfile
setfattr: testfile: Operation not permitted
Which is the filesystem in use (in bricks) ? If ext3/4, you may need
to mount it with user_xattr option to enable extended attribute
support, XFS has it enabled by default though.
Thanks,
Santosh
Mount:
09:49:13 :( ⚡ touch testfile && setfattr -n security.NTACL -v foo
testfile
setfattr: testfile: Operation not supported

Hi,
I have an issue with xattrs with the security prefix. This
command work in all the servers involved (bricks, clients) in all
the filesystems mounted (including the bricks), but fails on the
volume mounted in the clients.
touch testfile && setfattr -n security.NTACL -v foo testfile
If I try "-n whatever", works.

All the boxes have the same version.
Hints are welcome :)
