Where is the best place for LUKS to sit in a RAID/LVM/LUKS stack?

  • 772

I am implementing a server storage setup making use of software RAID, LVM and LUKS.

I can think of three combinations this configuration could take:

  1. RAID, LVM, LUKS
  2. RAID, LUKS, LVM
  3. LUKS, RAID, LVM

In which order would these best be configured in, where best is in terms of security and maintainability?

linux lvm security software-raid

  1. I would make the RAID array first because when you will change a disk of the array, it will be tranparent for LUKS and LVM.

    If there is no need to keep some partition unencrypted (except for the /boot partition), I would setup LUKS in second because I don't want to have to setup LUKS every time I make a change in my partitions.
