Strange results from FDISK?????
Hi all,
I am writing script that returns the size of each disk or partition when called. I am using FDISK -l and parsing the results to get the result I want. When I execute fdisk -l it shows correct results, BUT when I execute the same thing with results to be put in a variable, I get strange results:
Quote:
[root@APPSERVER programs]# fdisk -l 2>/dev/null | grep /dev/hda1
/dev/hda1 * 1 2709 20480008+ 7 HPFS/NTFS
Quote:
[root@APPSERVER programs]# result=`fdisk -l 2>/dev/null | grep /dev/hda1`
[root@APPSERVER programs]# echo $result
/dev/hda1 duplicate linux Microsoft Word - This week..pdf partition redundancy week6.pdf windows 1 2709 20480008+ 7 HPFS/NTFS
[root@APPSERVER programs]#
When I want the output to be put in $result variable, fdisk -l returns the files in the folder as well. Another example: When I execute from /:
Quote:
[root@APPSERVER /]# result=`fdisk -l 2>/dev/null | grep /dev/hda1`
[root@APPSERVER /]# echo $result
/dev/hda1 backup backups bin boot dev dhcpcd etc extra home initrd lib lost+found media mnt opt partition proc root sbin srv sys tmp usr var 1 2709 20480008+ 7 HPFS/NTFS
Can anybody tell me why this thing happens? I'm running mandriva 2008.1 by the way.
Thanks

pvresize
PVRESIZE(8) System Manager's Manual PVRESIZE(8)
NAME
pvresize - resize a disk or partition in use by LVM2
SYNOPSIS
pvresize [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--setphysicalvolumesizesize] PhysicalVolume [PhysicalVolume...]
DESCRIPTION
pvresize resizes PhysicalVolume which may already be in a volume group and have active logical volumes allocated on it.
OPTIONS
See lvm(8) for common options.
--setphysicalvolumesize size
Overrides the automatically-detected size of the PV. Use with care, or prior to reducing the physical size of the device.
EXAMPLES
Expand the PV on /dev/sda1 after enlarging the partition with fdisk:
pvresize /dev/sda1
Shrink the PV on /dev/sda1 prior to shrinking the partition with fdisk (ensure that the PV size is appropriate for your intended new parti-
tion size):
pvresize --setphysicalvolumesize 40G /dev/sda1
RESTRICTIONS
pvresize will refuse to shrink PhysicalVolume if it has allocated extents after where its new end would be. In the future, it should relo-
cate these elsewhere in the volume group if there is sufficient free space, like pvmove does.
pvresize won't currently work correctly on LVM1 volumes or PVs with extra metadata areas.
