This is a bug in e2fsadm which will be fixed with LVM 0.8.
As a workaround you can perform the steps manually.

To extend the file system:

  e2fsck     - required by resize2fs
  lvextend   - resize the lvol
  resize2fs  - resize the fs

To reduce the file system:

  e2fsck     - required by resize2fs
  resize2fs  - resize the fs
  lvreduce   - resize the lvol


Hope this helps
Michael
