I have the following setup:
sda (new installation) sda1 sda2 sda3 (LVM-LUKS) root swap sdb (old installation) sdb1 sdb2 sdb5 (LVM-LUKS) root (old) swap
The goal is to have
/home/user/other mounted at boot time.
sda operates correctly during the boot, but
sdb refuses to mount root or see its swap.
I have currently added a second line to
/etc/crypttab, now it looks like this:
sda3_crypt UUID=uuid-for-sda3 none luks,discard sdb5_crypt UUID=uuid-for-sda3 none luks,discard
This has resulted in the appearance of
/dev/mapper/sdb5_crypt, and it links correctly to a newly-appeared
/dev/dm-3. However, unlike
sda3 it doesn't "expand" its partition table.
I have tried to boot into a live-usb, there i can mount either of the drives successfully; but i cannot mount both at the same time. This leads me to believe that it maybe a problem with some internal naming scheme, for example both maybe trying to usurp "xubuntu--vg-root" as the mapper name, and thus only the first one succeeds in that task.
