Hello! I used the instructions on http://deb.riseup.net/storage/encryption/loop-aes/ to create a encrypted area. But when I get to the 'dd' stage (using /dev/loop1 and /dev/md2), weird things starts to happen. I should have plenty of memory total used free shared buffers cached Mem: 3116936 3095872 21064 0 178824 2545060 -/+ buffers/cache: 371988 2744948 Swap: 1951888 772 1951116 cookiemonster:~/VMware# At the time of the problem, swap was less then 50MB in use.
