<i><span style="font-size:9.5pt">I found the issue.<br>
<br>
The CentOS 7 RPMs, upon upgrade, modifies the .vol files. Among other things, it adds "option shared-brick-count \d", using the number of bricks in the volume.<br>
<br>
This gives you an average free space per brick, instead of total free space in the volume.<br>
<br>
When I create a new volume, the value of "shared-brick-count" is "1".<br>
<br>
find /var/lib/glusterd/vols -type f|xargs sed -i -e 's/option shared-brick-count [0-9]*/option shared-brick-count 1/g'</span></i><u></u><u></u></p>
