well, as i said, i know how to get there manually. there are multiple ways to get there with software raid, btrfs raid, lvm, luks. but everything the installer doesn't support is hard to install on, and will produce unpredictable failures on upgrades, i was asking if there is a way the installer supports. ext filesystems don't have encryption either and the installer lets you encrypt them (using luks) and i tried something similar as described in my original mail under procedure 3) and after the installer completed it didn't boot up, i don't want to manually repair bootup every time some updates fiddle around with initrd or such.

Hi,
I have spent some time now trying to set up my notebook with a software raid 1 built from 2 SSDs and encrypted btrfs and so far failed miserably.
Sseems the installer doesn't support this combination at all.
What i tried:
All those attempts have been tried with and without a separate unencrypted /boot and /boot/efi. I only would need encrypted root and home, boot can be unencrpyted if needed.
1) Raid + Encrypted Btrfs When creating btrfs on a raid device, the encryption checkbox is disabled, while it's available for other filesystems.
2) Raid + Encrypted LVM While creating "normal" LVM Partitions has a encryption checkbox, the installer directly uses raid devices in the LVM creation interface, encryption option nowhere to be seen.
3) Raid + Manual cryptsetup I created a raid 1 and did a manual cryptsetup on it. The installer detects the encrypted raid and asks for a password. From there on the installer seems to work as expected. Can create a LVM on the encrypted raid (also the installer shows correcty that it's encrypted), i can create my needed filesystems and the installer completes without errors. Sadly the installed system fails to boot. At this point i've given up and haven't investigated further.
I would know how to do all necessary stuff manually i probably manage to make everything boot up, but i don't want to intervene with standard setup too much, as this probably will cause problems with future upgrades / updates.
Did i miss something or is it really impossible to combine raid + btrfs+ encryption at the current state of the installer?
Best Regards
Daniel
btrfs doesn't support encryption yet, but btrfs+RAID+LUKS is possible. Take a look a this page to get an idea on what you need to do: https://www.peterbeard.co/blog/post/i-am-a-data-hoarder-or-how-to-create-a-b...
