GlusterFS provides it's own NFS server which exports glusterfs volumes.
If an NFS client is used to mount a glusterfs volume at boot time it's likely that the mount will be executed in fstab before the gluster-nfs server is ready.
There was a similar issue when using the glusterfs FUSE client (mount type "glusterfs") which I fixed by adding a wait-for-state task to upstart.
Something similar is needed for NFS mount types as well.
