[linux-lvm] Reducing/Resizing LVM where "/" filesystem is included in the LVM



Hi,

I am a newbie to linux and I have XP and FC3 on my 30GB HD.
I have searched through internet to find out how to reduce logical
Volume based on LVM2, but as my situation is quite different hence could
not find out any solution.
I have total 3 Primary partions and one extended partitions.
first 3 primary paritions are NTFS(XP),FAT32(data) and NTFS(data)
respectively.
Extended partition contains two partitions, linux boot and linux LVM.
Linux LVM contains one Group Volume which contains two Logical Volumes.
One Logical Volume has / root file System
and other Logical Volume has SWAP space.


Here is the ouput of fdisk -l and contents of /etc/fstab

fdisk -l

Disk /dev/hda: 30.0 GB, 30005821440 bytes

/dev/hda3   /mnt/win_ntfs_e     ntfs    ro,defaults,umask=0222 0 0
================================================================================

Now I want to free some space from the linux LVM(hda6) and create a
FAT32 partition as hda7.

So how to reduce that LVM?


one more questions my /boot parition is /dev/hda5 but in fstab it shows
it as LABEL=/boot
so how is that?

Thanks.

-ajeet.
