Lost in transition (Syno > Unraid)

[guilhem31]

Hello everybody:)

 

Firts of all, this is gonna be a BIG post plus english is not my mother langage. I’m quite a noob regarding servers / homelabs... so I appologize if I’m not easily understable / if I don’t understand well…. ^^

 

I would like to know if someone would help me migrating from my current setup to the new I just bought. I know this have been allready duscussed a lot, but as a total Unraid beginner I’d like to make sure I can control 100 % of the process.

 

Let’s start with my current setup :

 

Synology DS418play

With 3x6To drive + 1x3To drive, in one SHR Volume (btrfs if I’m not wrong).

The Volume is 13,2To. 9To are used.

 

For my new server i bought all the hardware needed (MB, CPU, PSU… etc.) and 1x8To drive (for parity), 2x500Go SSD drives (for mirrored cache).

 

The problem is : as I’m not rich enough to buy multiple BIG drives, I can’t just move data from one to the other in 1 step.

 

So here is the starting point :

 

 

I would like to know if the steps I describe below would be the right way to go :

 

STEP 1 :

 

 

- I move about 6To of data on my Disk 5 (using USB connection to my DS418 NAS… will be SLOWWWW)

 

STEP 2 :

 

 

- I have to move the Disk1 to the Unraid server. I don’t know how Sonology would agree with that… I read that my NAS will be running in degraded mode, hoping nothing wrong happens.

- Then I create an array in my Unraid server with only Disk1 > is it only possible ?

 

 

STEP 3 :

 

 

- Once the Disk1 is ready, I plug Disk5 in the unraid server as an unassigned drive and copy the data on Disk1 (probably faster than USB)

 

STEP 4 :

 

 

- I unplug Disk5 from Unraid, re-plug it on my Synology

- I then move the data from Disk2/3/4 to Disk5

 

 

STEP 5 :

 

 

- I move the Disk2/3/4 from Synology into the Unraid server, and add it to the array.

 

STEP 6 :

 

 

- I move the Disk5 into Unraid server

- I move all the data from Disk5 in the array

- I assign Disk5 as parity

 

 

I would love someone to help me, explain me if I’m wrong and how I should operate other way if needed.

 

This is the first set of probably A LOT of questions I’ll be asking here ^^

Thanks for reading !

That should work, just make sure disk5 is formatted with an fs supported by UD.

I think exfat woukd be a good choice, am I right ?

[JorgeB]

Thats's supported by UD, so it's fine.

[guilhem31]

And another question (to try to do everything faster) :

What if I shutdown my Synology NAS

Remove Disk1, put it in unraid server

Put Disk5 in unraid server

Then copy 6To of data on Disk5.

Both drives would be unassigned drives.

 

It would be really fast compare to USB transfert right ?

 

[JorgeB]

It would be faster but pretty sure Unraid/UD won't be able to mount that disk, even if you had the other raid members there.

Ok, I don't want to complicate everything ao I think I'll stick to the first plan !
