I am trying to mount a 3TB external Volume with Truecrypt on my Raspberry Pi (Raspbmc). I had the same Problem with raspbian running on the Raspberry Pi and dont know how to solve it. I found many other guys having trouble with this issue. Can someone give me some advise please?
pi@raspbmc:/dev$ truecrypt /dev/sda1 /media/extern1 Enter password for /dev/sda1: Enter keyfile [none]: Protect hidden volume (if any)? (y=Yes/n=No) [No]: Error: /dev/mapper/control: open failed: No such device Failure to communicate with kernel device-mapper driver. Check that device-mapper is available in the kernel.
