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_setup_vps_disk

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

NAME

       dtc_setup_disk - setup LVM disks for using it as a VM

SYNOPSIS

       dtc_setup_vps_disk.sh VPS_NUMBER HDD_SIZE SWAP_SIZE [ lvm|loopback ]

DESCRIPTION

       dtc_setup_vps_disk.sh 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 create partitions to be used by a VPS later on.  It will create a normal partition that will be used as a root disk,
       and a swap partition.

       dtc_setup_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool.

       If the partition(s) exists, then this script will delete it/them first.

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.

       HDD_SIZE Size in MB of the VPS partition to create.

       SWAP_SIZE  Size in MB of the VPS swap partition to create. If the dtc-xen SOAP server is used to create the VPS, then it will create a swap
       partition of the exact same size as the memory.

       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 15360 256 lvm

       This will create 2 LVM partition to be used by the VPS named xen04, the first one being a root partition of 15 GB, and the second one being
       a swap partition of 256 MB.

VERSION

       This documentation describes dtc_setup_vps_disk version 0.3.15.	See http://www.gplhost.com/software-dtc-xen.html for updates.
