Description of problem:

Tried to mount a subdir on client, after providing the required authentication.
The mount command throws error, 
[2014-06-11 03:38:50.353145] E [mount3.c:888:__mnt3_resolve_export_subdir_comp] 0-nfs-mount: Failed to resolve and create inode: parent gfid 00000000-0000-0000-0000-000000000000, entry 999

although the mount is successful


Version-Release number of selected component (if applicable):
glusterfs-3.6.0.14-1.el6rhs.x86_64

How reproducible:
seen several times

Steps to Reproduce:
1. create a new 6x2 volume, start it
2. mount over nfs 
3. create some directories in this volume.
4. set nfs.export-dirs off
5. provide authentication to a client for a certain directory to allow the client to let it mount the directory. for authentication use the command nfs.export-dir
6. mount the directory on the client.

Actual results:
mount command,
[root@rhel6 nfs-test-dir]# mount | grep nfs-test-dir
10.70.37.215:/dist-rep1/4rename/999 on /mnt/nfs-test-dir type nfs (rw,vers=3,addr=10.70.37.215)

nfs.log,
[2014-06-11 03:38:50.353145] E [mount3.c:888:__mnt3_resolve_export_subdir_comp] 0-nfs-mount: Failed to resolve and create inode: parent gfid 00000000-0000-0000-0000-000000000000, entry 999

This issue is a problem as it throws error with a zero gfid.

Expected results:
there should not be any error of this kind. 

Additional info:
subsequent umount and mount does throw the error
Comment 3 Niels de Vos 2014-10-23 15:55:05 UTC 
This is not reproducible with glusterfs-server-3.4.0.59rhs-1.el6rhs.x86_64 anymore. Following the steps in comment #0 does not result in the error message.

Please re-open if this problem is still happening in a current version.
