Bug#804629: linux-image-amd64: Cannot mount LVM RAID1 file system at boot

Sorry but as said in my previous post I'm still experiencing the issue 
even with the kernel version 4.9 from backports.

Sorry, but the bug is still present!

As Jarek Kamiński himself said:

I haven't test to activate and deactivate the logical volume, therefore 
I experience the issue every time on system reboot (but I will make a 
go).


Here is what I get on logs (sorry for not posting earlier):
