Yes, you should not mount the lower block devices, only the /dev/drbd1
device. Take any lower devices out of /etc/fstab.<br>

<div>DRBD was syncing between node1 and node2 and when I rebooted
node1 I got this from cat/proc/drbd:</div>
<div>1:r0 Connected Secondary/Secondary Diskless/UpToDate</div>
<div><br>
</div>
<div>So I ran:</div>
<div>drbdadm up r0</div>
<div><br>
</div>
<div>and got the above error.</div>
<div><br>
</div>
<div>Is the lower device the actual partition the drbd device is on
which is my case is /dev/sda2?</div>
<div><br>
</div>
<div>Should that /dev/sda2 not be mounted at boot?</div>
<div><br>
</div>
<div>What do I do to make DRBD happy on reboot?</div>
<div><br>
</div>
<div>Thanks!</div>
