<p class="MsoNormal"><span style="" lang="EN-US">Hi,<br>
<br>
I got this problem yesterday. fsck did not fix the filesystem so I umount it
and recreated it. The system is running now but I am afraid that this problem can
happen again.<br>
<br>
I am using LVM (VolGroup04-LogVol00) and created de filesystem using
/dev/drbd0.</span></p>
