Code:
 grep -q "^[^#]*/dev/$b\>" /etc/fstab && continue
  uuid=$(blkid -s UUID -o value /dev/$b)
  # jump to next loop cycle if its UUID is present and in fstab
  [ -n "$uuid" ] && grep -q "^[^#]*$uuid" /etc/fstab && continue
  # echo -e is discouraged, the echo options can differ between shells

what do the above lines do and what if the disk are partioned with lvm and mounted in the below format
Code:
/dev/mapper/vg_lv_home /home                 
/dev/mapper/vg_lv_tmp /tmp                   
/dev/mapper/vg_lv_u01 /u01

dtc_kill_vps_disk

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

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.
