Seems you
- expanded your LVM2 container c00 by hdd,
- created a region r00.01 in it,
- expanded your LVM2 container c01 by that region and
- expanded the r01.

You should have simply added hdd to the LVM2 container c01 and would
have been able to expand r01 - depending on the filesystem even w/o
umounting r01 first.

To undo the change, you need to 
- shrink r01 to the old size (afaik reiserfs can do that mounted and
  ext3 unmounted; with other fs you probably need to backup, delete,
  recreate and restore the volume in the old size),
- move the mapping of the shrinked volume r01 from r00.01 to the rest of
  c01 in case r01 still uses space on r00.01,
- shrink c01 by r00.01,
- delete r00.01 from c00 and
- shrink c00 by hdd.
