<p>Some days ago all my glusterfs configuration was working fine. Today I
realized that the total size reported by df command was changed and is
smaller than the aggregated capacity of all the bricks in the volume.</p>
<p>I checked that all the volumes status are fine, all the glusterd
daemons are running, there is no error in logs, however df shows a bad
total size.<br>
