Root Partition Backup and Restore
on ifmwera1 and ifmwera2

Backup:

• Shut down the running system
• Remove both data disks (/dev/sda1 and /dev/sdb1) and plug in a "free harddisk" containing a filesystem (reiserfs or ext 3 or ...)
• Start a RESCUE System from the original DVD, CD or FLOPPY as distributed by SuSE.
  (kernel version 2.4.19)
• Login as root
• Insert the diskette with hpt37x2.o driver module for RocketRaid133 Controller.
• Mount the floppy ( mount /dev/fd0 /floppy )
• Load the hpt driver module ( lsmod /floppy/hpt37x2.o )
• Mount the output disk to store the root disk image ( mount  /dev/sda1 /mnt )
  ( it is assumed that the removable hard disk on /dev/sda1 is a formatted block device AND containes NO data )
• create the mountpoint eg. /org ( mkdir /org )
  
• mount the root partition to /org ( mount /dev/hda2 /org )
  
• Copy the mounted root partition (/org) into a tar-archive on (/mnt)
  ( cd /org; tar -cpvf /mnt/hda2.tar .) , time to copy (or coffee break): about 30 minutes or more

Restore:

• Shut down the running system
• Remove both data disks (/dev/sda1 and /dev/sdb1) and plug in the backup disk containing the tar-archive of /dev/hda2
• Start a RESCUE System from the original DVD, CD or FLOPPY as distributed by SuSE.
  (kernel version 2.4.19)
• Login as root
• Insert the diskette with hpt37x2.o driver module for RocketRaid133 Controller.
• Mount the floppy ( mount /dev/fd0 /floppy )
• Load the hpt driver module ( lsmod /floppy/hpt37x2.o )
• Mount the disk containing the compressed "root disk image" ( mount  /dev/sda1 /mnt )
• Create desired partitions on /dev/hda
  ( fdisk /dev/hda )
  press <m> for help:  create a swap partition "/dev/hda1" (1-300 blocks), create a primary partition "/dev/hda2" (301-rest blocks)
  press <w> to write the new partition table on the disk,
  the type of partition can be changed with <t>, type 82 for linux swap, type 83 for Linux primary part.
• restart the computer by real hardware reset
• Create a reiser-filesystem on /dev/hda2 (mkreiserfs /dev/hda2 )
• Create a mount point, eg. /org ( mkdir /org )
• Mount the new disk ( mount /dev/hda2 /org )
  
• Decompress and copy the tar-archive to the desired partition
  ( tar -xpv -C /org -f /mnt/hda2.tar ), time to copy (or coffee break): about 30 minutes or more
• Repair grub on the boot disk:
  ( cd /org/sbin )
  ( grub )
  ( grub> root (hd0,1) )
  ( grub> setup (hd0) )
  ( grub> quit )
  ( shutdown -r now ) "restart the computer"
