Comment 5 for bug 908387

This also applies to encrypted root using the following configuration chosen during 11.10 setup:

- Partition disks - manual:
 sda:
  new partition table: yes
  parititions sorted by position on disk:
   partition 1 - 1GB, Name: <empty>, Use as: Reserved BIOS boot area, Bootable flag: off
   partition 2 - 4GB, Name: <empty>, Use as: Physical Volume for raid, Bootable flag: off
   partition 3 - remaining space (3TB), Name: <empty>, Use as: Physical Volume for raid, Bootable flag: off
 sdb:
  new partition table: yes
  parititions sorted by position on disk:
   partition 1 - 1GB, Name: <empty>, Use as: Reserved BIOS boot area, Bootable flag: off
   partition 2 - 4GB, Name: <empty>, Use as: Physical Volume for raid, Bootable flag: off
   partition 3 - remaining space (3TB), Name: <empty>, Use as: Physical Volume for raid, Bootable flag: off
 sdc:
  new partition table: yes
  parititions sorted by position on disk:
   partition 1 - 1GB, Name: <empty>, Use as: Reserved BIOS boot area, Bootable flag: off
   partition 2 - 4GB, Name: <empty>, Use as: Physical Volume for raid, Bootable flag: off
   partition 3 - remaining space (3TB), Name: <empty>, Use as: Physical Volume for raid, Bootable flag: off

 select "Configure software RAID":
  Create MD device - RAID1, active devices: 3, spare devices: 0, using the 4GB disks: sda2, sdb2, sdc2
  Create MD device - RAID5, active devices: 3, spare devices: 0, using the 3TB disks: sda3, sdb3, sdc3

 back to partitioning menu, now configure the raid devices' usage:
  under "RAID1 device #0 (4GB)" select part "#1 4.0GB":
    use as: ext3, mount point: /boot, mount options: noatime, label: none, reserved block: 5%, typical usage: standard

  RAID5 device #1, configure "#1 6.0TB":
    use as: physical volume for encryption,

    encryption parameters - leave those at default if you are no mathematician:
     encryption method: device-mapper (dm-crypt), encryption: aes, key size: 256, iv algorithm: cbc-essiv:sha256, encryption key: passphrase, erasa data: NO if disks were randomized before, YES otherwise

 select "Configure encrypted volumes:"
   select "Create encrypted volumes" - devices to encrypt: /dev/md1
   now select "Finish" and enter the passphrase when asked

 back to the partitioning menu again:
  NOW notice the follwing bug in the partitioner: the ext3 raid device for "/boot" is NOT marked as being used for "/boot" anymore!
  - correct its parameters, now you must also set "Format the partition: yes" because it was formated before when we first configured it and we want it to be clean.

  under "Enccrypted volume (md1_crypt)" select part "#1 6.0TB":
   use as: xfs, mount point: /, mount options: noatime, label: none

  finish partitioning and write changes to disk. boot the system when the raid becomes degraded: yes. return to the partitioning menu to create swap: no. write changes to disk: yes.
