title: Gluster remove-brick from volume failed, what to do to remove a brick?
body: <p>I had a gluster volume named <code>data</code> of distributed mode. I added a brick <code>server1:/vdata/bricks/data</code> to the volume <code>data</code>, However I found that <code>vdata/bricks/data</code> is on the <code>/</code> disk of linux. I wanna remove the brick from volume. So I use <code>gluster volume remove disk data server1:/vdata/bricks/data start</code>. Then I check the status using <code>gluster volume remove-brick data server1:/vdata/bricks/data status</code> but found the status is failed, and the scanned files is always 0. So what could I do to remove this brick without lossing data?</p>
