I am assuming that you already know how to set up an encrypted file system using cryptsetup with luks (or something else). There are several howtos. I am also assuming that you are familiar with LVM2. This tutorial deals only with how to add an extra encrypted physical volume to a volume group pool containing other encrypted physical volumes. This is typical scenario if, at first, you have set up your encryption at a physical partition level (/dev/sdaX where X is the a number of your partition), then you setup your LVM on top of the encrypted partition. If at some later time you want to add another partition in your volume group, you will also want to have it encrypted in order to maintain the same level of security. In order for your machine to boot, initramfs needs to be able to unlock both PVs in order to reconstruct the entire volume group where your root lv is lying. For those of you familiar with LVM2 and looking to securely encrypt data on your logical volumes, this article provides a great step-by-step tutorial on how to do so. This implementation requires passwords to be typed for each volume - maybe you can let us know how this would be done with a keyfile?.

Encrypted filesystems may be overkill for family photos or your résumé, but they make sense for network-accessible servers that hold sensitive business documents, databases that contain credit-card information, offline backups, and laptops. EncFS and Loop-AES, which are both released under the GNU General Public License (GPL), are two approaches to encrypting Linux filesystems. I'll compare the two and then look at other alternatives. . EncFS provides an encrypted filesystem in userspace and runs without any special permissions. In fact, it's not so much a filesystem as a program that translates requests (encrypting or decrypting them as appropriate) and passes them to the underlying filesystem.
