Mounting Encrypted Partions

I am having some problems mounting encrypted partions during the boot process. Now, I can mount and open the partion as root from the command line: Using

cryptsetup luksOpen /dev/hda2 home
mount /dev/mapper/home /home

Problem is during boot I get this error

[code]Failed to setup dm-crypt key mapping.
Check kernel for support for the aes-cbc-essiv:sha256 cipher spec
and verify that /dev/hda2 contains at least 133 sectors.
Failed to read from key storage.[/code]

If you need to know my kernal it is 2.6.19-1.2895.fc6; it does have support for encryption.

Well thanks, BTW I am trying to do this off a guide==>

Does it have something to do with autoloading the dm_crypt module? Thanks for any help! :)

EDIT: Had to retype kernal

Nevermind, I have found the problem and have fixed it. Now to be perfectly complete, I realized that Fedora Core 6 provides basic support for encrypted non-root file systems. Thusly, no need for the luksopen script. "editing /etc/rc.d/rc.sysinit and dm_crypt module autoloading"

instead it is enough to create /etc/crypttab:
[CODE]hda2 /dev/hda2 none cipher=aes-cbc-essiv:sha256 [/CODE]

this creates an encrypted block device /dev/mapper/hda2, which can be referenced in /etc/fstab.

Man, I rule, I am just awesome... [b]>.>[/b]
