If you're using FC5 then you can launch system-config-lvm. It will let you resize
ext3 volumes dynamically and graphically.

Otherwise, the procedure for resizing:
1) With filesystem unmounted:

  a) Unmount the filesystem
  b) Grow the lvm: lvresize -L +500M /dev/vgname/lvname
  c) fsck the filesystem: e2fsck /dev/vgname/lvname
  d) Resize the filesystem: resize2fs /dev/vgname/lvname
  e) Remount the filesystem: mount /dev/vgname/lvname /path/to/mount

2) With filesystem mounted:

  a) Grow the lvm: lvresize -l +500M /dev/vgname/lvname
  b) Resize the filesystem: ext2online /path/to/mount
