Resizing to a smaller partition
 

I've installed Fedora 9 on my laptop, assigning all the available disk space to the default layout partitioning.

df -hal
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
182G 9.4G 163G 6% /
proc 0 0 0 - /proc
sysfs 0 0 0 - /sys
devpts 0 0 0 - /dev/pts
/dev/sda1 190M 19M 162M 11% /boot
tmpfs 1.3G 200K 1.3G 1% /dev/shm
none 0 0 0 - /proc/sys/fs/binfmt_misc
sunrpc 0 0 0 - /var/lib/nfs/rpc_pipefs
fusectl 0 0 0 - /sys/fs/fuse/connections
gvfs-fuse-daemon 182G 9.4G 163G 6% /home/Karl/.gvfs

I wish now to get a new partition (8-10 Gb let's say) for installing a new distro. How can i do this without destroying all i have?
Also, i was thinking about reducing the size of tmpfs partition: 1.3 looks a bit an overkill, to me.

With gparted i have /dev/sda so partitioned:
sda1 partition, file system ext3, flagged as boot (190M, Used 20 Mb)
sda2 partition, file system unknown, flagged as LVM. (186 Gb, i cant see however how much space is used having an exclamation mark on it)

in sda2 i find
/dev/mapper/VolGroup00-LogVol01p1, file system linux-swap, 1.94Gb that i can resize, format, etc. etc
/dev/mapper/VolGroup00-LogVol00p1 (with the exclamation mark near it), file system ext3, 184.12 Gb. I cant see how much used and how much left and i cant do anything but unmount it.

There is a way to resize this partition in order to retrieve the 10 Gb?

Thank you anticipately

Use the PartedMagic Cd for resizing and moving partitions.
