Public bug reported:
A bit similar to "30 seconds boot delay when root fs is on lvm":
https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1807499
I installed Kubuntu 19.04 with 2 LVM volume groups (one per disk). My root and
my /usr are both located on the same LVM. Mounting /usr takes 30s, but if I
move the /usr to a non-LVM partition then the mounting takes no time and the
whole boot process is very fast.
In the script "scripts/local" of initramfs-tools, there is a 30s timeout called
"slumber" passed to the "wait-for-root" program (from initramfs-tools-bin), and
the wait comes from there (I could see it by adding traces before and after).
If I decrease the timeout to 10s, the system can still boot correctly (and 20s
faster).
I don't know if the problem comes from the initramfs-tools scripts, from
wait-for-root or from the integration in (K)Ubuntu.
