As a follow up, I created a test gluster cluster, installed 3.6, and upgraded it to 3.7. I verified client machines running glusterfs 3.6 and 3.7 could mount the volume via glusterfs…
So currently, clients running 3.7 can’t mount a gluster volume via glusterfs if the gluster servers are running 3.6.x. I didn’t test mounting the volume via NFS. When it fails it still returns an authentication error. Not sure if this is a bug or just requires specifically setting some authentication parameters on the volume/cluster.

Yesterday one of our admin ran a yum update on his Centos 6.6 machine, and it updated the gluster client to 3.7.3. (Client update only on his machine, not the gluster cluster servers). After the update he was not able to mount the gluster volume. He then removed and reinstalled the 3.6 gluster client, and he was able to mount the volume again. So to test/confirm, I did the same thing. Prior to the running the upgrade I was running 3.6.4 glusterfs and glusterfs-fuse, and I had the mountpoint mounted on my test server. I ran the yum update glusterfs, it completed successfully, and I could access the mount. I then unmounted the gluster mount, and when I tried to mount it, and I received the following error: Mount failed. Please check the log file for more details. Since I could access the mountpoint, it appears something has happened in this update to change default behavior from a client mount request. Any ideas what changes I need to make to be able to mount the volume? With 3.7 version of client, do you have to specifically set auth.allow options for volumes?
