* Upgrade of benjamin <2011-10-06 tor>

The server benjamin was upgraded to Debian GNU/Linux 6.0 Squeeze in accordance with the [[http://www.debian.org/releases/squeeze/i386/release-notes/ch-upgrading.en.html][upgrading release notes]]. 

At some point the raid array did not mount so the installation was interupted. Mdadm was used to setup the software raid:

   : $ cat /proc/partitions
   : $ cat /etc/mdadm/mdadm.conf
   : # mdadm --misc --query /dev/sdc1 /dev/sdd1; # for display
   : # mdadm --misc --examine  /dev/sdc1 /dev/sdd1; # for display
   : # mdadm --misc --examine --scan
   : # mdadm --assemble --scan

Then also the logical volume management (LVM) was needed to set up. 

   : # vgdisplay
   : $ ls -1 /dev | grep 2T; # shows nothing
   : # vgchange --available y 2T_vg-backup
   : $ ls -1 /dev | grep 2T; # shows VG 2T_vg-backup
   : # cryptsetup luksOpen /dev/2T_vg-backup/backup backup
   : # sudo mount -t ext4 /dev/mapper/backup /mnt/backup

The =/etc/fstab= is no longer correct since "ext4dev" is not a supported file system. Instead "ext4" should be used. 

** Things to do after upgrade

   - Remove the following packages
     - apticron (will be replaced by unattended-upgrades)
   - Check logcheck rules
   - Check rkhunter (root kit hunter) configurations
   - Check NTP (network time protocol) configuration
