| Hi,
Mounted GlusterFS volume with native mount and ACL’s are working as expected, mounted same volume with nfs protocol and the result is exactly the same as I described below. ACL set to files work and ACL set to directory do not work as expected. Ohh, I’m out of ideas :(

Enabled trace for few moments and tried to make any sense of it by searching for lines containing ‘acl’ according to this everything kind of works except lines which state that “remote operation failed” GlusterFS failed to replicate or commit acl changes?

Thanks Niels, your hints about those two options did the trick although
I had to enable both of them and I had to add nscd (sssd provides user
identities) to this mix as well.
Now back to the problem with ACL’s. Is your test setup something like
this: GlusterFS 3.7.2 replicated volume on Centos/RHEL 7 and client or
clients accessing GlusterFS volumes by NFS protocol, correct?
As Jiffin had suggested, did you try the same command on GlusterFS Native mount? Log levels can be increased to TRACE/DEBUG mode using the command 'gluster vol set <volname> diagnostics.client-log-level [TRACE,DEBUG]' Also please capture a packet trace on the server-side using the command - 'tcpdump -i any -s 0 -w /var/tmp/nfs-acl.pcap tcp and not port 22' Verify the packets sent by Gluster-NFS process to the brick process to set the ACL. Thanks, Soumya # gluster volume info acltest

Maybe there is a way to increase verbosity of nfs server which could
help me to trace this problem. I did not find any good hints for
increasing verbosity of nfs server in documentation.

Hi,
Another issue with NFS and sec=sys mode. As we all know there is a
limit of 15 security ids involved when running NFS in sec=sys mode.
This limit makes effective and granular usage of ACL assigned through
groups almost unusable. One way to overcome this limit is to use
kerberised NFS but GlusterFS does not natively support this access
mode . Another option, at least according to one email thread, states
that GlusterFS has an option server.manage-gids which should mitigate
this limit and raise it to 90 something. Is this the option, which
can be used for increasing sec=sys limit. Sadly documentation does not
have clear description about this option, what exactly this option
does and how it should be used.
server.manage-gids is an option to resolve the groups of a uid in the
brick process. You probably need to also use the nfs.server-aux-gids
option so that the NFS-server resolves the gids of the uid accessing the
NFS-server.
The nfs.server-aux-gids option is used to overcome the
AUTH_SYS/AUTH_UNIX limit of (I thought 32?) groups.
The server.manage-gids option is used to overcome the GlusterFS protocol
limit of ~93 groups.
If your users do not belong to 90+ groups, you would not need to set the
server.manage-gids option, and nfs.server-aux-gids might be sufficient.
HTH,
Niels

Hi,

setfacl for dir on GlusterFS volume which is NFS mounted to client
system
1. same command is used for setting ACE, no error is returned by
that command
2. get acl
#getfacl test

If I use ordinary file as a target on GlusterFS like this
setfacl -m g:x_meie_sec-test02:rw dummy
then ACE entry is set for file dummy stored on GlusterFS
# getfacl dummy
user::rw-
group::r--
group:x_meie_sec-test02:rw-
mask::rw-

So, as you can see setting ACLs for files works but does not work
for directories.
This all is happening on CentOS7, running GlusterFS 3.7.2
Hi Jyri,
It seems there are couple of issues ,
1.) when u set a named group acl for file/directory, it clears the
permission of others too.
2.) named group acl is not working properly for directories ,
I will try the same on my setup and share my findings.

In my setup (glusterfs 3.7.2 and RHEL 7.1 client) it worked properly
I followed the same steps mentioned by you.
#cd /mnt
# mkdir dir
# touch file
# getfacl file
# file: file
# owner: root
# group: root
user::rw-
group::r--
other::r--
# getfacl dir
# file: dir
# owner: root
# group: root
user::rwx
group::r-x
other::r-x
# setfacl -m g:gluster:rw file
# getfacl file
# file: file
# owner: root
# group: root
user::rw-
group::r--
group:gluster:rw-
mask::rw-
other::r--
setfacl -m g:gluster:r-x dir
getfacl dir
# file: dir
# owner: root
# group: root
user::rwx
group::r-x
group:gluster:r-x
mask::r-x
other::r-x
So can u share the following information from the server.
1.) gluster vol info
2.) nfs.log (nfs-server log)
3.) brick logs
and also can u try the same on fuse mount(gluster native mount).

Subject: GlusterFS 3.7.2 and ACL
Hi
Setup:
GFS 3.7.2, NFS is used for host access
Problem:
POSIX ACL work correctly when ACLs are applied to files but do
not work when ACLs are applied to directories on GFS volumes.
How can I debug this issue more deeply?
Can you please explain the issue with more details, i.e what
exactly not working properly , is it setting acl or any
functionality issue, in which client?
