Can you use LVM on top of Luks?
Once finished, attribute the key file to the volume: Using LVM on top of LUKS may not be necessary according to your needs. In this case, it’s a bit redundant as the scheme is: one “disk” volume = one LVM physical volume = one LVM virtual group = one LVM logical volume.
How to full encrypt your Linux system with LVM on Luks?
In this tutorial i will show you how to full encrypt your system using two linux native tools: LVM (for partitioning) and LUKS (for the actual encryption). Why LVM on LUKS? Imagine you have your hard drive divided in at least two partitions: one for the root of your system and the other used as a swap partition.
Which is the only partition to be unencrypted with LVM?
The only partition that must be unencrypted is the boot partition, so for the most secure setup, we will use an external device for it. Using the LVM partitioning we won’t even need to create a partition table, we will use the raw disk instead. Why do it from command line?
How do you wipe a disk in Linux?
There are different ways to “wipe” disks in linux: wiping with zeros (which seems sufficient against all attacks that don’t use specialized hardware such as an electron microscope ). You can also use random data and several passes, but then it takes much longer.
Can you store partition size in Luks dm-crypt?
Yes, you can, as neither dm-crypt nor LUKS stores partition size. Whether you should is a different question. Personally I recommend backup, recreation of the encrypted partition with new size, recreation of the filesystem and restore. This gets around the tricky business of resizing the filesystem.
How to resize Luks partition ( shrink or extend encrypted )?
Use aes-xts-plain64 for that. As you see performing resize LUKS partition, extend or shrink encrypted LUKS partition are not recommend. Now earlier I had shared steps to encrypt partition device /dev/sdb1 using LUKS but here I would like to use LVM as backend storage device to perform resize LUKS partition with ext4 as file system.
Can a virtual machine install a Luks partition?
Using PXE server you can install Oracle Virtual Machines or KVM based Virtual Machines or any type of physical server without any manual intervention saving time and effort. So I will quickly create LVM based LUKS encrypted partition.
