If you have enough disk space to accomodate your data *without*
compression you could do the following:
- boot a 'rescue system' (I recommend knoppix) from CD or usb
- mount both your partition and the one with the free space
- rsync -avx your data to the free space
- reformat your partition to ext3 (all data will be lost, so make sure
you have good backups!)
- rsync all your data back to the new ext3-partition
- adjust your /etc/fstab (replace reiserfs by ext3)
- cross your fingers and reboot
tar would work on similar lines. tar can use compression, rsync is
probably faster (plus you have all your files as a backup; if one of
those files would get corrupted not everything is lost).
Take care that you properly understand each step, verify the options. Be
aware that a typo may lead to data loss...
Take care, good luck!
