As my NAS-hardware doesn't have a HW-RAID controller (HW is a Thecus N16000) I have,
as far as I understand, two options:

- create a SW-RAID and then LVs on this SW-RAID
- directly create LVs with the existing disks

First question: is that true?

And if it is... second question:
what are the advantages / disadvantages of these two options?

Thanks a lot!
