[Gluster-users] NFS Mounted GlusterFS, secondary groups not working

[Mike Hanby]

After upgrading my servers to 3.1.1 I'm still experiencing the issue with secondary groups not working with the client using NFS:

In this scenario root owns the directory and the admins non primary group (of which my id is a member) is the group:

$ groups
mikeh admins

$ ls -ld /research/project/
drwxrwx--- 10 root admins 73728 Nov 22 12:13 /gluster/project/

$ ls -l /gluster/project/
ls: /gluster/project/: Permission denied

$ mount|grep research
nas-01.mydom:/research-storage on /gluster type nfs (rw,addr=192.168.1.11)

Both Gluster servers and the client are CentOS 5 x86_64 systems. The servers had glusterfs-core / glusterfs-fuse 3.0.1-1 updated to 3.1.1-1 via the RPMs. The storage is a simple distributed file system, no striping or replication.

Following the update I rebooted both servers and remounted the NFS file system on the client.

I'll add this info to the bug as well.

Thanks, that looks to be the same issue. I'll add my comments to the bug.

Hi,

It might be related to a bug filed at:
http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2045

If you please update it there or file a new one, I'll take a look. Thanks.
