Hi Noah,You might be able to achieve this with ecryptfs, from Ubuntu.
It can mount an encrypted drive with unencrypted-passthrough; you can then run around rewriting all the files to convert them.
ie.
mount -t ecryptfs encrypted crypted
find -type f crypted -exec rewrite_file \{\} \;
where rewrite_file does something like
cp $FILE tmp_file
rm $FILE
mv tmp_file $FILE

Hey all,
I have a few cases where I'd like to encrypt without taking the system down for extended periods, ie, servers.
In the windows/apple world truecrypt / bitlocker / filevault will all let you encrypt the root partition as a background process, throttled to a low IO load. Usually this requires a reboot to get started, then runs in the background.
Does anyone know how to achieve this in the Linux world? (preferably with luks)
