I found a real problematic configuration that need to be fixed.
When you install a system based on lvm2 logical volume mapped on a software raid volume, the initrd don'tactivate the lvm raid volumes and so system may hang definitely.

I add a simulation made by VirtualBox instance simulating what I have found.
This is a critical issue because a correct configuration made system impossible to launch (see movie from 00:09:15...)

There is also another bug in yast that bring up a "strange" error (see movie at 00:03:55)

I noticed that in systems where I recordered the problem in the mkinitrd there is no /etc/mdadm.conf. So I tried to recover with:

cd /etc
echo 'DEVICE containers partitions' > ./mdadm.conf
mdadm  --examine  --scan --config=mdadm.conf >> ./mdadm.conf

And it seem that system boot correctly
But please verify that this is the only problem.

I'm facing the problem with lvm2, with all the workaround I've found that there is a process:
lvmetad
that sometimes freeze completely all the lvm commands
in that situation e.g.
"lvscan -v" freezes.
If I kill the process
lvscan -v complaining that there isn't lvmetad answer my question
So probably there something related to lvmetad cacheing service?

Sorry for the late reply. I don't know whether you are still facing the problem.
Would you please update to the newest lvm2 in opensuse13.2 or opensuse:Factory  and see if the issue still exists?

 thanks.
