WIerdness when creating Loop-aes file?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Running Debian 3.1

I am not sure what other info is useful?
