<span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">I have an 8 node gluster cluster running 3.6.2. 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).<o:p></o:p></span></p>

<span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">After the update he was not able to mount the gluster volume.

<span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">He then removed and reinstalled the 3.6 gluster client, and he was able to mount the volume again.<o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:0in;margin-right:7.5pt;margin-bottom:0in;margin-left:7.5pt;margin-bottom:.0001pt;line-height:21.6pt">

<span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">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.

<span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">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:<o:p></o:p></span></p>

<span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">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?<o:p></o:p></span></p>
