Boot hangs while adding swap
Boot process hangs after reaching the following line:
Code:
Adding 5853176k swap on /dev/mapper/mch-swap_1. Priority:-1 extents:1 across:5853176k

Using knoppix 6.2 as LiveCD, and mounting the partitions, I got the following:
Code:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
/dev/mapper/mch-root /               ext4    errors=remount-ro 0       1
# /boot was on /dev/cciss/c0d0p1 during installation

/dev/mapper/mch-swap_1 none            swap    sw              0       0

Code:

/dev/cciss/c0d0p1: UUID="1ed04531-7af8-44bb-9f5f-37a2cd53c93c" TYPE="ext2"

/dev/mapper/mch-swap_1: UUID="25f06ce3-c242-4e6e-b5e0-5ffc28aec059" TYPE="swap"

Is there any problem in fstab?
Please help me. I could not reinstall the server.

lvrmboot

lvrmboot(1M)															      lvrmboot(1M)

NAME

       lvrmboot - remove LVM logical volume link to root, primary swap, or dump volume

SYNOPSIS

       autobackup] dump_lv] vg_name

   Remarks
       cannot be performed if the volume group is activated in shared mode.

DESCRIPTION

       This  command  is  supported for arguments belonging to volume groups version 1.0.  Attempting this command with arguments belong to volume
       groups version 2.0 or higher will result in an error.

       The command updates all physical volumes contained in the volume group vg_name such that the logical volume is removed as a  root,  primary
       swap, or dump volume when the system is next booted on the volume group.

   Options and Arguments
       recognizes the following options and arguments:

	      vg_name		The path name of the volume group.

	      Set automatic backup for this invocation of this command.
				autobackup can have one of the following values:

				Automatically back up configuration changes made to the logical volume.
				       This is the default.

				       After  this  command  executes, the command (see vgcfgbackup(1M)) is executed for the volume group to which
				       the logical volume belongs.

				Do not back up configuration changes this time.

	      Remove the definition of
				dump_lv as one of the dump volumes.  Update the Boot Data Reserved Area.

				This option will be obsolete in the next HP-UX release.

	      Remove the definitions of all of the root, primary swap,
				and all dump volumes from the given volume group.  Update the Boot Data Reserved Area.

	      Remove the definition of the primary swap volume
				from the given volume group.  Update the Boot Data Reserved Area.

				This option will be obsolete in the next HP-UX release.

	      Print verbose messages.
