Problem solved! Thought I will post it.

I was missing the step of resizing the filesystem on the raided
volume. My raided volume was called md1. Calling
"resize_reiserfs /dev/md1" on both the nodes solved
the problem. Earlier I was only calling "drbdadm resize all"
followed by "reisize_reiserfs /dev/drbd0" on both nodes.

Also after the resize, I was not able to mount drbd0 on
either nodes. Unknown superblock error. Running fsck fixed
that issue.
