I think you are overwriting a partition and messing up your disk. You partition map, in other words, is wrong. Send us the output of
format < /dev/null

Then
format
0
pa
pr


Mine looks like this:
Part Tag Flag Cylinders Size Blocks
0 unassigned wm 0 0 (0/0/0) 0
1 swap wu 0 - 869 1.95GB (870/0/0) 4099440
2 backup wm 0 - 7505 16.86GB (7506/0/0) 35368272
3 root wm 870 - 7505 14.91GB (6636/0/0) 31268832
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0


Check your Cylinders column, and see if any of the numbers overlap (not including slice 2, which is the whole disk). If they do, then one partition is messing up another. For example, if above my swap was 0-911 instead of the 0-869 that I have, then 42 cylinders of swap would overlap into root (which starts at 870). This would cause me problems!

I wonder why you have partitioned the disk this way? root seems small. Maybe the users can fill up their partitions? Disks are so large these days, in the past it made sense for all kinds of stuff to be on different partitions but I might suggest you make your job a little simpler and just create root, swap, and oracle partitions.

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. SEE ALSO
