Cryptsetup Not Working i.e. "Is the dm_mod module loaded?"

hunterthomson · 2009-11-23 00:14:48

Helo,

Well, I had setup four encrypted partitions var,tmp,pkg,mail with the DmCrypt-LUKS Arch-WiKi.

All went well but I was stupid and used a dumb Key-file. Now I want to add a passphrase then remove the key-file. However, I can't use cryptsetup for some reason.

whenever I try to run cryptsetup I keep getting this...

$ cryptsetup luksAddKey /dev/sda6 
Command failed: Cannot communicate with device-mapper. Is the dm_mod module loaded?

$ modprobe dm_mod

$ cryptsetup luksAddKey /dev/sda6 
Command failed: Cannot communicate with device-mapper. Is the dm_mod module loaded?

$ sudo modprobe dm_mod
 
$ same thing...... Is the dm_mod loaded

$ sudo modprobe dm-mod

no luck

$ sudo pacman -S kernel26 kernel-headders && reboot

$  sudo pacman -S cryptsetup

no luck

I even added dm_mod  AND dm-mod   to the rc.conf MODULES array and Reboot

no luck

$ locate dm-mod.ko
/lib/modules/2.6.31-ARCH/kernel/drivers/md/dm-mod.ko
/lib/modules/2.6.31-aircrack/kernel/drivers/md/dm-mod.ko
/usr/src/kernel26-aircrack/pkg/lib/modules/2.6.31-aircrack/kernel/drivers/md/dm-mod.ko
/usr/src/kernel26-aircrack/src/linux-2.6.31/drivers/md/.dm-mod.ko.cmd
/usr/src/kernel26-aircrack/src/linux-2.6.31/drivers/md/dm-mod.ko



?????????????

Anyone know what could be wrong ?

Concidering I have reinstalled the kernel and the dm-mod.ko IS installed. I guess it must be ME that is the problem. I must me doing some little stupid thing wrong.

What could it be?

what exactly happens when you modprobe dm-mod as root?

nothing. As if it loaded the module.

So did it load correctly? (lsmod | grep dm-mod)

did you try to run cryptsetup as root?
