Title:
  cryptsetup fails for dmraid device

Status in “cryptsetup” package in Ubuntu:
  Expired
Status in “dmraid” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: cryptsetup

  When using cryptsetup on a dmraid device (fakeraid), cryptsetup isn't
  able to mount correctly root partition.

  For example, I've two SATA drives configured in RAID-1 (mirror) on an
  Intel raid controller supported by dmraid. My devices appears like
  that :

  $ ls -al /dev/mapper/
  total 0
  drwxr-xr-x  2 root root     200 Nov  4 22:10 .
  drwxr-xr-x 13 root root   14740 Nov  4 22:10 ..
  crw-rw----  1 root root  10, 63 Nov  4 22:05 control
  brw-rw----  1 root disk 254,  0 Nov  4 22:10 isw_djjhbadhab_Volume0
  brw-rw----  1 root disk 254,  1 Nov  4 22:10 isw_djjhbadhab_Volume01
  brw-rw----  1 root disk 254,  2 Nov  4 22:10 isw_djjhbadhab_Volume02
  brw-rw----  1 root disk 254,  3 Nov  4 22:10 isw_djjhbadhab_Volume05
  brw-rw----  1 root disk 254,  4 Nov  4 22:10 isw_djjhbadhab_Volume06
  brw-rw----  1 root disk 254,  5 Nov  4 22:10 isw_djjhbadhab_Volume07

  So I've setup encrypted partitions like that :

  $ cat /etc/crypttab 
  # <target name> <source device>         <key file>      <options>
  root_crypto     /dev/mapper/isw_djjhbadhab_Volume05     none    cipher=aes-cbc-plain,size=256,hash=sha256,tries=5,loud
  swap_crypto     /dev/mapper/isw_djjhbadhab_Volume06     /dev/urandom    swap

  $ cat /etc/fstab 
  # <file system> <mount point>   <type>  <options>       <dump>  <pass>
  proc            /proc           proc    defaults        0       0
  /dev/mapper/isw_djjhbadhab_Volume02 /boot           ext3    defaults        0       2
  /dev/mapper/root_crypto /               ext3    defaults,errors=remount-ro 0       1
  /dev/mapper/swap_crypto none            swap    sw              0       0

  initramfs has been rebuild via : update-initramfs -u -k all
  I use grub to boot using that kind of menu.lst :

  title           Ubuntu 7.10, kernel 2.6.22-14-generic
  root            (hd0,1)
  kernel          /vmlinuz-2.6.22-14-generic root=/dev/mapper/root_crypto ro irqpoll
  initrd          /initrd.img-2.6.22-14-generic

  But when my system boot, I got a : "cryptsetup: unknown fstype, bad password or options?"
  So I wait for initramfs to give me a shell, and as a workaround I do :

  cryptsetup remove root_crypto
  cryptsetup -y create root_crypto /dev/mapper/isw_djjhbadhab_Volume05
  mount -t ext3 /dev/mapper/root_crypto /root
  CTRL-D

  and the boot process just continue...
