While I'm trying to encrypt an external harddrive on a debian6 server I'm having some troubles running cryptsetup. I tested this with a usb memory stick and it worked fine on ubuntu but now I have this server with an external harddrive connected to it, and it returns an error:
Cannot initialize device-mapper. Is dm_mod kernel module loaded?
Presumably this means the dm_mod kernel module isn't loaded. My question here is where do I get this from and how do I make sure it will be loaded?
quick google search returned:
steven@server:~$ sudo modprobe dm_mod
FATAL: Error inserting dm_mod (/lib/modules/2.6.32-5-amd64/kernel/drivers/md/dm-mod.ko): Unknown symbol in module, or unknown parameter (see dmesg)
What could this be and what am I not doing that I should do?
btw, tried this on my ubuntu laptop: http://tipstrickshowtos.blogspot.com...into-your.html
