Franklin,
I tried that also.. It showed sec: dd if=/dev/zero of=/dev/sda1 bs=512 count=2048;sync: No such file or directory.

Just tried by removing single quote also.. it does not print anything for sec variable..

Thanks
amio

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.
