I have create a 2 node replicated cluster with GlusterFS 3.4.1 on Centos 6.4. Mounting the volume locally on each server using native client works fine, however I am having issues with a separate client only server that I wish to use NFS to mount the gluster server volume. 

Volume Name: glustervol 
Type: Replicate 
Volume ID: 6a5dde86-... 
Status: Started 
Number of Bricks: 1 x 2 = 2 
Transport-type: tcp 
Brick1: glusterserver1 :/mnt/glusterv0 
Brick2: glusterserver2 :/mnt/glusterv0 

On nfs client: 

mount -o vers=3 glusterserver1:/glustervol /mnt/glustervol 
mount: glusterserver1 :/ glustervol failed, reason given by server: Input/output error 

On gluster server (each time above mount is attempted): 

[2013-11-27 21:00:46.584733] E [afr-self-heal-common.c:197:afr_sh_print_split_brain_log] 0-glustervol-replicate-0: Unable to self-heal contents of '/' (possible split-brain). Please delete the file from all but the preferred subvolume.- Pending matrix: [ [ 0 2 ] [ 2 0 ] ] 
[2013-11-27 21:00:46.586009] E [afr-self-heal-common.c:2212:afr_self_heal_completion_cbk] 0-glustervol-replicate-0: background meta-data self-heal failed on / 
[2013-11-27 21:00:46.586091] E [mount3.c:290:mnt3svc_lookup_mount_cbk] 0-nfs: error=Input/output error 

Any help appreciated.
