Hi Christian,
Apologies, I couldn't get back to you sooner since Friday.
> 1. get your help to recreate the issue - what more than having
multipath devices and rebooting do I need? Any special setup to force it
to be more active in the initramfs?
Not really special setup needed. Actually no multipath devices needed.
On a 17.04 guest with a single virtio scsi disk, apt-get upgrade'd
yesterday, I just install multipath-tools-boot to hit this problem.
It happens in 3 reboots in a row.
No multipath devices required:
# ls -d /sys/block/sd*
/sys/block/sda
#
Just install multipath-tools-boot and reboot.
I see this error in 3 reboots in a row.
# apt-get install multipath-tools-boot
# dpkg -s multipath-tools | grep ^Version
Version: 0.6.4-3ubuntu2
# reboot
