[Gluster-users] Need advice on how to export directories

[Jeff White]

You can only mount sub dirs via NFS:

[root at login1-dev ~]# mount -t glusterfs 
storage0-dev.cssd.pitt.edu:/vol_home /mnt
[root at login1-dev ~]# echo $?
0
[root at login1-dev ~]# umount /mnt
[root at login1-dev ~]# mount -t glusterfs 
storage0-dev.cssd.pitt.edu:/vol_home/cssd /mnt
Mount failed. Please check the log file for more details.
[root at login1-dev ~]# echo $?
1
[root at login1-dev ~]# mount -t nfs -o tcp,vers=3 
storage0-dev.cssd.pitt.edu:/vol_home /mnt
[root at login1-dev ~]# echo $?
0
[root at login1-dev ~]# umount /mnt
[root at login1-dev ~]# mount -t nfs -o tcp,vers=3 
storage0-dev.cssd.pitt.edu:/vol_home/cssd /mnt
[root at login1-dev ~]# echo $?
0
[root at login1-dev ~]# ls /mnt
adc57  jar7  jaw171  SecurityScanSvc

 From the server side I don't think there is a way to limit what client 
can mount what subdir.  You control that at the volume level with the 
nfs.rpc-auth-allow option (see 'volume set' in the docs) but not at the 
subdir level.
