Hello,
Current state: Laptop with 1 TB encrypted drive running Ubuntu 16.04.
(The first few lines from luksDump and the output from `lsblk`, `blkid`,
and `df -h` is attached below.)
Would like a add a new 2 TB drive that is also encrypted and install
20.04 on it. Would like to keep the 16.04 alive till I have used 20.04
for a few months.
I came across these instructions:
https://www.erianna.com/adding-an-secondary-encrypted-drive-with-lvm-to-ubuntu-linux/
Questions:
1) Would it be good to follow those instructions, especially given that
I intend to install 20.04 on the new drive?
2) Or should I remove the 1 TB drive, add the new drive and install
20.04 on it. Then put both drives and boot -- and then do what to get
an unified view of the two separately encrypted drives?
3) Or should I just add the new drive, boot from a 20.04 USB and install
on the new drive, with the installation steps taking care of whatever
would need to be done? If so, what would be the options to select
during the install?
Thanks.
