There is really no way to create a RAID1 from an already used HDD to a wiped one?
It really makes no sense to me, because raid 1 is simply a copy, so there should'nt be any problem to do that 
For what I know even Windows can do that!
extend mirror from a not wiped HDD

- OMV 2.x

What's issue here? you have HDD that you want to add to your current mirror and that HDD is already being used?
Or you want a single drive, that's already formatted and mounted to convert it to RAID1?
For what I know even Windows can do that!
This is the linux village.

I believe that is related to this thread:
So my first guess would be:
He is trying to run a raid1 on from the OS disk. That is not supported - end of story.The other thread is dealing with it.
Once you have installed the OS on the USB/Flash drive, you should be able to wipe both HDDs.
Find out the name of the disks (e.g. sda/sdb) and then overwrite the first two MB with DATA like:
WARNING: ALL DATA ON BOTH DISKS ARE LOST FOREVER!
dd if=/dev/zero of=/dev/sda size=2M
dd if=/dev/zero of=/dev/sdb size=2MThat actually removes all headers and partitions from the disks and you can then create a raid with OMV with both.

I've never used it but look at raider.I can think of lots of things Linux can do that Windows can't...

I know, that's the reason why I thought that linux had a function like that
i'll look for raider, but the last update is from 4 years ago, i'm not really sure about using it -
It still works. Not many mdadm functions have changed.
