Hi Gull04,

I tried your way. But changes were not reflected in /etc/fstab or /etc/mtab file.

do i need to restart the server for changes to reflect in the file ?

I have fstab in below format

Code:
tmpfs                   /dev/shm                tmpfs   defaults        0 0

expected result after command executed.
Code:
tmpfs                   /dev/shm                tmpfs   defaults,nodev        0 0


Kindly guide.

NAME
dtc_kill_vps_disk - destroy LVM disks for freeing space SYNOPSIS
dtc_kill_vps_disk VPS_NUMBER [ lvm|loopback ] DESCRIPTION
dtc_kill_vps_disk This shell script is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server. This script is used to delete a partitions that was used by a VPS. It will delete the normal partition that was used as a root disk, and the swap partition. dtc_kill_vps_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool. OPTIONS
VPS_NUMBER has to be a number between 01 and 19. Let's say the number is 16, and that dtc-xen is configured to use the volume group called lvm1, then this script will create /dev/lvm1/xen16 and /dev/lvm1/xen16swap. IMAGE_TYPE This parameter can have 2 values: either lvm or loopback. If ommited, then lvm is used. If lvm is used, then this script will create a partition using lvmcreate, otherwise it will create an image file. Both will later be used for the VPS. EXAMPLE
dtc_setup_vps_disk 04 lvm This will delete the 2 LVM partitions that were used by the VPS named xen04, the first one being the root partition, and the second one being the swap partition. VERSION
This documentation describes dtc_kill_vps_disk See http://www.gplhost.com/software-dtc-xen.html for updates. SEE ALSO
