Todd,
Thanks for the reply. My answers are in the text. What I can't understand
is that I did the same on both machines but it is only one that I am
having trouble with.

Neither /etc/auto.master or /etc/auto.misc have anything that is not
commented out.

I'm using:
rpm -q drbd
drbd-0.7.17-1.c4
I get the error when starting drbd. I am using the rpm from the Centos
repo which provides a kernel module for my kernel. I have also installed
the drbd-heartbeat group rpms.
I am starting drbd with the script:
/etc/rc.d/init.d/drbd start
If I use drbdadm I get:
drbdadm up drbd1
ioctl(,SET_DISK_CONFIG,) failed: Invalid argument
Lower device is already mounted.
Command 'drbdsetup /dev/drbd1 disk /dev/hdd1 internal -1' terminated with
exit code 20
