[Gluster-users] unable to remove ACLs

[lejeczek]

hi guys

I have a simple case of:
$ setfacl -b
not working!
I copy a folder outside of autofs mounted gluster vol, to a
regular fs and removing acl works as expected.
Inside mounted gluster vol I seem to be able to
modify/remove ACLs for users, groups and masks but that one
simple, important thing does not work.
It is also not the case of default ACLs being enforced from
the parent, for I mkdir a folder next to that problematic
folder and there are not ACLs, as expected.

glusterfs 3.12.9, Centos 7.4

Any thoughts, suggestions?
many thanks, L.

Are you mounting glusterfs with -o acl ? In the case you are not, mounting
with option acl is necessary for glusterfs to honor ACLs.

surely I'm. Otherwise I'd have no "working" acls, right?
Like I say, I can operate setfacl and this seems to work
except, I cannot remove acl completely with "-b" which
should just work, right?

I think it should be easily reproducible, my setup is pretty
"regular". I'm on Centos 7.4 and mount via autofs/manuall.
Anybody can check that?

Yes, it should ideally work.

I think it should be easily reproducible, my setup is pretty "regular".

Here's a test that passed with a manual mount while using 3.12.9:

[***@deepthought ~]# mount -t glusterfs -o acl deepthought:/foo
/mnt/gluster
[***@deepthought ~]# cd /mnt/gluster/
[***@deepthought gluster]# setfacl -m u:nobody:rw foo
[***@deepthought gluster]# getfacl foo
# file: foo
# owner: root
# group: root
user::-w-
user:nobody:rw-
group::r--
mask::rw-
other::r--

[***@deepthought gluster]# setfacl -b foo
[***@deepthought gluster]# echo $?
0
[***@deepthought gluster]# getfacl foo
# file: foo
# owner: root
# group: root
user::-w-
group::r--
other::r--


Can you please share the sequence of acl commands that causes "setfacl -b"
to fail in your setup?

Thanks,
Vijay
