i'm not sure on this one. i assumed having noauto in fstab for the
mount point would be sufficient. i'm guessing this is going to take
some tinkering and i don't really have any suggestions. sry.<br>

<p class="MsoNormal">drbd wont allow the drbd device on the secondary
drbd server
to be used. you'll probably get something like media errors back when
you try
to mount or otherwise use the device. only the primary can be used. so
if you
want to mount this on the secondary, you need to promote it to primary
(which
will demote the current primary) and then mount the volume. this will
then mean
the volume cant be mounted on the now old primary.<br>

<p class="MsoNormal">ummmm. yeah. something else is using the
underlying device.
it is mounted to /home. maybe lsof wont show the device if it is just
mounted.<br>
<br>
either way, you need to umount /home restart drbd so that drbd can
claim the
device, /dev/md1. you would then want to change your fstab to point
/home to
/dev/drbd1 instead of /dev/md1.<br>
