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

[SW Riccardo Scartozzi]

I've just had the chance to try again now. Sorry but I had to try on a 
different server.

I confirm you that it works!
The logical volume with raid1 has to be created on kernel linux 4.9, if 
the raid is created on different linux version (as it was my first case) 
it won't be possible to activate it neighter after switching to kernel 
4.9!!!

I can then also confirm that the activation of lvmetad is totally 
irrelevant.

So I can confirm what Jarek Kamiński said: the bug is solved since 4.9.

Thank you again,
