<p class=MsoNormal>We setup four nodes connected to an iSCSI SAN with 3 ocfs2
volumes.<o:p></o:p></p>
<p class=MsoNormal>Last Friday, one of the volumes was set read-only because of
the following error:<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So we unmounted the volume and started fsck.ocfs2. It’s
now been running for 3 days, with only one message:<o:p></o:p></p>
<p class=MsoNormal>Pass 0a: Checking cluster allocation chains<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The volume is 8TB, with about 300GB used. Should it be
running for so long?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks for your help - Xa<o:p></o:p></p>
