Encrypyted filesystems on linode
I'm assuming it's possible but I've never actually tried. I could not find anything in the wiki.
I setup a new disk called xvdf and ran:
cryptsetup luksFormat /dev/xvdf ( Type 'YES', enter passphrase ) cryptsetup luksOpen /dev/xvdf xvdf-crypttest ( enter passphrase ) mkfs -t ext4 /dev/mapper/xvdf-crypttest mkdir /crypt-test mount /dev/mapper/xvdf-crypttest /crypt-test
I don't intend to use this in production, I just wondered if it would work.
DRBD is the next thing to play with.
