<p class="MsoNormal"><span style="font-family:"Tahoma",sans-serif;color:#2e74b5">After OS update to CentOS 7.4 or RedHat 6.9 and update to Gluster 3.12.4, the ‘df’ command shows only part of the available space on the mount point for multi-brick volumes. All
nodes are at 3.12.4. This occurs on both servers and clients. <u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-family:"Tahoma",sans-serif;color:#2e74b5">Configuration 1: A distributed volume of 8 bricks with 4 on each server. The initial configuration had 4 bricks of 59TB each with 2 on each server. Prior to the update to CentOS
7.4 and gluster 3.12.4, ‘df’ correctly showed the size for the volume as 233TB. After the update, we added 2 bricks with 1 on each server, but the output of ‘df’ still only listed 233TB for the volume. We added 2 more bricks, again with 1 on each server. The
output of ‘df’ now shows 350TB, but the aggregate of 8 – 59TB bricks should be ~466TB.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-family:"Tahoma",sans-serif;color:#2e74b5">Configuration 2: A distributed, replicated volume with 9 bricks on each server for a total of ~350TB of storage. After the server update to RHEL 6.9 and gluster 3.12.4, the volume
now shows as having 50TB with ‘df’. No changes were made to this volume after the update.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-family:"Tahoma",sans-serif;color:#2e74b5">In both cases, examining the bricks shows that the space and files are still there, just not reported correctly with ‘df’. All machines have been rebooted and the problem persists.<u></u><u></u></span></p>
