You need to use a cluster-aware filesystem such as ocfs2 or gfs to be
able to mount a DRBD device on both boxes at the same time. it looks
like you are mounting the underlying /dev/sd* block device, not /dev/drbd1.

I am stuck.
I did in an initial install of DRBD and was able to achieve a sync
from primary to secondary!
Maybe.
My partition that is source on primary and destination on secondary is:
/dev/sda2 /data
When I create files in the /data directory I can see that DRBD is
recognizing that things are changing and when I run:
cat /proc/drbd
on both primary and secondary I see they both change if I modify or
add files in /data on the primary.
My question is why do I not see those same files on /data on the
secondary?
Shouldn't they be there?
Here is the output of cat /proc/drbd from both systems:
