Subject: [dm-crypt] Encrypted Btrfs RAID1
Date: Wed, 11 Sep 2013 20:13:12 +0200	[thread overview]
Message-ID: <5230B2B8.9060604@gmx.de> (raw)

Hello all,

I have been using LUKS for quite some time now to encrypt block devices.
Up to now I have always used the setup RAID1 -> Encryption -> LVM2 ->
filesystems.
Now however I want to create an encrypted Btrfs RAID1. The problem is
that a RAID based on Btrfs is not based on block devices. What I would
need is to encrypt two different partitions and then use their decrypted
counterparts as basis for the RAID. The problem is that I really don't
want to add my pass phrase multiple times and I don't like key files. I
realize that the 'reuse key' problem is a long standing issue:

https://www.martineve.com/2012/11/02/luks-encrypting-multiple-partitions-on-debianubuntu-with-a-single-passphrase/

However I did not find a solution anywhere.
Could you tell me how to setup my system to make things work the way I
intend to?

Regards,
ax487
