How to shrink root file system (LVM) in Linux Fedora 9?
My root file system is of type LVM. i wanna shrink it but unable to do so.
When i give the below command:
Code:
resize2fs /dev/mapper/VolGroup00-VolLog00 10000M

it messages that online shrink can't can't be done as the logical volume is mounted on /. i switched to single user mode by giving command:
Code:
shutdown -i 1 now

There also, it messages the same. it says that online resizing(shrinking) is not available.

i tried by giving a few commands below but my system messaged that command doesn't exist. ( not sure whether these commands are really there or not, just a try)
Code:
ext2online /dev/mapper/VolGroup00-VolLog00 10000M
ext2resize /dev/mapper/VolGroup00-VolLog00 10000M
 /

What i intend to do is: i w'd reduce the LVM and the space avalialble after that , i w'd make one more logical volume in which i w'd install Ubuntu 12.10. i hope i can install this way keeping Fedora as well as windows.

pvck

PVCK(8) 						      System Manager's Manual							   PVCK(8)

NAME

       pvck - check physical volume metadata

SYNOPSIS

       pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       pvck checks physical volume LVM metadata for consistency.

OPTIONS

       See lvm for common options.

       --labelsector sector
	      By  default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0.  This parameter allows you to specify a
	      different starting sector for the scan and is useful for recovery situations.  For example, suppose the partition table is corrupted
	      or  lost	on  /dev/sda, but you suspect there was an LVM partition at approximately 100 MB.  This area of the disk may be scanned by
	      using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

	      pvck --labelsector 204800 /dev/sda

	      Note that a script can be used with --labelsector to automate the process of finding LVM labels.
