Trying to seperate disk functions or at least understand what I should do?

[jhmariscal]

Coming from a failed QNAP and liked what I saw with UNRAID. I get that UR is NOT RAID. That's fine and all. Still, trying to figure out how I would recreate my prior 6 bay situation.

 

Prior I had 4x 4tb Red NAS drives acting as my main utilized system. This was in a RAID 6, so I had roughly 8TB usable.

The I had 2x 8TB Archive drives set in RAID 1 and placed a lot of storage data that was not often touched.  Because of the way ARCHIVE drives are shingled (as I understand it), they should not be used for multiple concurrent read/ writes.

 

Now, I have the 4x 4TB drives set

Parity

Parity 2

Disk 1

Disk 2

(and then added a 1TB Evo 870) for Cache.

Does this look right for the array to 'mimic' the Raid 6 setup I had prior? Thanks.

 

The next question would be on how to incorporate the 2x8TB ARCHIVE drives to use in a similar fashion as prior without messing with read/ write ability of above? I would effectively want them to act as a mirrored array for long term storage data.

 

Advice? Better usage?

If you are using the 6.9 beta series, you could set up your 2 archive drives in a second cache pool using BTRFS RAID1.

Thanks jonthanm - Not using 6.9 beta series. Since I am new, concerned about stability.   Should I be?

The core is stable, there are some display details and minor things being worked on. I'm running beta on 3 out of 4 of my machines.

Thanks @jonathanm. Can you tell me if the below looks right a basic setup (again, trying to get close to 'mimicking' RAID 6?

Sorry- Also, once I have the drives in, how would I set up the second cache pool using BTRFS RAID1?

[jhmariscal]

Hello- Can anyone assist with my question?

 

[JonathanM]

Can you post a screenshot of the MAIN GUI with what you have done so far?

[jhmariscal]

[JonathanM]

I don't see the 2ea 8TB drives in the Unassigned section. Are they connected?

[jhmariscal]

Sorry, I dont have the 2x8TB drives in yet. I was only asking on how so I could prep.

 

Do the main drive setup look correct to you?

[JonathanM]

Looks good so far.

 

With the 2 8TB drives connected and the array stopped, just click Add Pool and go from there.
