LinuxQuestions.org - increased reiserfs partition size

I recently repartitioned my laptop to make better use of space. In order to do this, I cloned my Gentoo root and boot partitions with Ghost 4 Unix 2, so I wouldn't have to reinstall. My boot partition uses the ext3 filesystem, while my root partition uses reiser. My root partition was increased from about 17GB to 20GB.

I was successfully able to clone my Gentoo installation back onto the partitions, and everything works except for one little problem. The `df` command still reports a filesystem size of 17GB. I suppose the reiser filesystem doesn't know that it's partition is larger than before. Is there anyway to make reiser use up the remaining 3GB? Both cfdisk and parted report the 20GB size, it's just reiser that can't see it. Any suggestions would be appreciated.

Here is the partition table reported by cfdisk:

Code:

                                                      cfdisk 2.12q



                                                  Disk Drive: /dev/hda

                                            Size: 30005821440 bytes, 30.0 GB

                                  Heads: 240  Sectors per Track: 63  Cylinders: 3876

      hda6                                Logical        Linux ReiserFS                                  20336.77

Here is the output of df:

Code:

Thanks for you help!
