I just copied and pasted the example drbd.conf from drbd.org website.

I can ping the 2 interfaces.  I am not trying to make it talk to the other
node yet.  I am just trying to get the drbd0 partition to format on the
first node.  Once I can over come this I will get the two talking.

I get the same error when I use mkfs.ext3 /dev/drbd0.  I am just an old
linux guy and still have mke2fs on the brain.  I am running slakware v11.0
UDEV is installed but was not running which I corrected now.  I have never
had a reason to run it until now is the why not.

mknod /dev/drbd0 b 147 0 fixed the error message below when compiling a
kernel and when I try to mkfs.ext /dev/drbd0 I am now getting this error
msg which is different.



root at area51:/etc/rc.d# mke2fs /dev/drbd0
mke2fs 1.38 (30-Jun-2005)
mke2fs: Wrong medium type while trying to determine filesystem size
