Hi,
before you start telling me to go and search - I did, for two days. And I haven't found any information that I would consider answers to my questions.
I have two main questions.
1) Do I need RAID support on my motherboard in order to use RAID-related stuff in NAS. Or in more detail - is my assumption correct that if the motherboard supports RAID 0 and 1 (=NOT 5), I can NOT use RAID 5 within FreeNAS?
I guess the answer is yes, but I also believe that if you do RAID on motherboard, you set it up on BIOS level. Not on OS level. And FreeNAS is an OS. Therefore one of my assumptions must be false.
I'm just unable to find which one.
2) There are many parts involved. I mean HW parts. Let's say that there are not important parts and important parts.
Not important are drives - because I will use the whole RAID stuff to be able to overcome a drive to fail. But also processor - because I believe that if my processor dies, I'll by a new one that fits and boot - and still see my data. That's why they are not important.
But then there is something important. I'm not sure what, either motherboard, or bootable storage or ...something else.
Important because when I replace it, I'm not going to boot.
Such part I'd have to replace and install fresh OS. And then what happens to my data sitting on the drives.
Btw in this case I assume that as soon as I turn on RAID of any type (even mirroring), every single drive is unreadable for another computer.
So if one of my important parts dies, how do I get back to my data?
