    Sorry, my fault. For mount failure, first thing is to check if your

    probably<br>
    a compatible issue: see the &quot;FEATURE FLAGS&quot; section in `man ocfs2` <br>

    Quote from `man ocfs2`:<br>
    &quot;&quot;&quot;<br>
    DETECTING FEATURE INCOMPATIBILITY<br>
    <br>
                  Say one tries to mount a volume with an incompatible
    feature. What happens then? How does<br>
                  one detect the problem? How does one know the name of
    that incompatible feature?<br>
    <br>
                  To begin with, one should look for error messages in
    dmesg(8). Mount  failures  that  are<br>
                  due to an incompatible feature will always result in
    an error message like the following:<br>
    <br>
                  ERROR: couldn&#39;t mount because of unsupported optional
    features (200).<br>
    <br>
                  Here  the  file  system is unable to mount the volume
    due to an unsupported optional fea-<br>
                  ture. That means that that feature is an Incompat
    feature.  By  referring  to  the  table<br>
                  above,  one can then deduce that the user failed to
    mount a volume with the xattr feature<br>
                  enabled. (The value in the error message is in
    hexadecimal.)<br>
    &quot;&quot;&quot;<br>
    <br>
    Please show your dmesg.<span class="HOEnZb"><font color="#888888"><br>
