Yes, I have rebooted many times. Right now, I'm using them in a working
system. What's more, I have two systems prepared similarly, one with
raid and one without, and they are showing exactly the same problem.
Here, have a look at one of these systems (raid). All the disks
sd{a,b,c} are random filled with no luks header. They are mounted with
an external header. sd{a,b} contain root/home and sdc (not mounted) is
just data.
