[Gluster-users] unable to change group ownership for some groups

[Frank Van Damme]

Hi group/list,

I am in the process of trying out Glusterfs, and I have come across a 
rather strange permission issue. The problem is this:
I have one user (my personal account) who is unable to set group 
ownership of a file to certain groups. 

frvdamme at rondon /mnt/TEST $  chgrp group1 glfilme /tmp/localfile
chgrp: changing group of `glfile': Operation not permitted

I am member of the group. 
I own the files. 
Other users, members of that group, CAN chgrp the file.
I can read files owned by group1, even with permissions g+r,o-rwx, where 
I am not the owner.
It happens with a number of groups, but not all of them. 
I even tried my luck in the storage backend on the server, where the 
files are saved with verbatim permissions, and I am allowed to chgrp the 
files as a non-root user.

All my users and groups are in LDAP, buth server and client side - in 
fact, I have a replicated brick on two servers, and the machine above is 
one of them. So I am mounting the volume on one of the servers. 
(For the record, I have an NFS server running somewhere else, and LDAP 
groups work just fine client to server). 

I checked for duplicate uid's or gid's in the passwd file, but there are 
none. 

OS: Debian 7
GlustgerFS version: 3.6.8, both client and server (since they are the 
same machine in the example). 

Clarifications are welcome.
