Here is a brand new Ubuntu Budgie 20.10 user who has recently migrated from the Debian+LXDE combo for a number of reasons being the desktop GUI and fresher software two of them.
My setting is: laptop with the disks:
/dev/sda 1TB HD (old one)
/dev/sdb 720GB SSD (new one, replacing DVD-ROM inside a caddy)
My goal is to use LVM encrypted and set:
/dev/sdb 720GB has:
efi in the /dev/sdb 720GB, taking 512MB
/boot in in the /dev/sdb 720GB, taking 1GB, as ext4
all remaining space, as physical volume encrypted and
/ in the /dev/sdb 720GB
/dev/sda 1TB has a new partition and then select physical volume encrypted:
/home in the /dev/sda 1TB, so the whole disk /dev/sda will be used by /home
So far, I have run over 5 attempts but cannot find a way to get this setting working when booting the Ubuntu Budgie ISO from a USB flash drive.
Could anyone please cast some light on this issue and clarify?
I have read already a number of guides online but have not found one that attempts to use LVM encrypted across two hard drives so I am addressing you for support.
I thank you for your time and advice and wish you all a great 2021 ahead!
This definitely isn’t my area so just a few pointers.
The official ubuntu support forums askubuntu.com and ubuntuforums.org should be consulted as well since this is a generic issue.
A brief look around and it appears luks is a one disk solution… well at least that’s as far as my limited knowledge here goes.
A few results mentions using alternate file systems such as btfrs probably trying to tie the two disks to appear as one logical device for luks to work.
I found this blog as well … seems to be quite involved but maybe well give some pointers
