I reproduced the problem in a tiny test system as follows:

I created a virtual machine with VMWare running on my Mac.  It has a virtual DVD-drive (loaded with the Jessie 8.1.0 amd64 install image) and three virtual disk drives.  One virtual disk is a small (1 GB) drive to hold /boot.  The other two (4GB each) to be configured at installation time as a software RAID0 housing a single LVM2 physical volume with three logical volumes for root, home, and swap.

When installed with Jessie, everything works fine.

Then I did full-upgrade to Testing/Stretch.  Everything still works fine.

Then I did full-upgrade to Unstable/Sid, and it broke.

When i disabled use_lvmetad in /etc/lvm/lvm.conf and did “update-initramfs -u” things went back to working.

I don’t expect the choice of VMWare as a platform has anything to do with this problem, so you can probably duplicate this procedure with a different VM platform…

The output of lsblk looks like this:

If it matters, the VM has two virtual CPUs and 2 GB of virtual RAM.

Hope it helps!
