Hello everyone,
It seems that my mainboard is defective and I now want to assemble a new server.
My question now is this:
1. how can I make sure that when I have reinstalled everything with my current 2x SSDs, 1x NVMe and my 8 SATA HDDs and my USB boot medium with UNRAID on it will work as before after the first power-on?
2. what do I have to consider beforehand?
3. if I have forgotten anything else for the change, please let me know.

Thank you for your time

You don't really need to do anything. That's the beauty of UnRaid. The config is on the flash drive and is portable. 

However, I would suggest:

On the new system, make sure the devices show up in BIOS.

Run memtest on the new system to verify the ram.

If you're changing from non-UEFI to UEFI, you might need to rename the EFI- directory on the flash to EFI. 

After booting, you can re-run the sensors-detect for dynamix if needed

Thank you @foo_fighter, that sounds much easier than I thought.
Then I only have to check my RAM on the new system as I already had a UEFI BIOS before.

1. do I have to reactivate the license for new hardware or inform the UNRAID team about the new hardware for activation?
With regard to a new USB stick, you have to rewrite the license, but since my stick has remained the same, I assume that I don't have to do anything.

2. i will open a separate thread for build advice. Is this the right place? Home>Community>Hardware : https://forums.unraid.net/forum/9-hardware/

Best regards

as already said: you do not have to do anything. The license is bound to the stick, not to the computer.

So if you put the stick elsewhere, it still is activated.

 

The only nothing thing I’d do is just take a photo/screenshot of your drive assignments just in case you need to manually reassign them on the new system.

 

The most important one is knowing which disk(s) is parity so you don’t end up with assigning a data drive in the parity slot(s). That would be the only way you’d lose data.

How can I check this if I no longer have access to the local system dashboard? Unfortunately, the system no longer starts. Is it possible to find the mapping somewhere on the USB drive?
I could connect my USB drive to a notebook and boot from it and then screenshot the assignments.
Provided the Unraid system accepts the “new” network card from the notebook on its own. 
Since I don't integrate the data carriers, it shouldn't be a problem, or does the hardware from the NB, for example, destroy the hardware configuration of the current defective system on the stick?

 

 

PS. Here I have opened a thread to build a new system, if you want to help me ->

How were your HDDs connected to your old mainboard? Directly via SATA ports or through an HBA or some other adapter/splitter?

 

if they were directly connected to the boards SATA ports you shouldn’t have issues with unraid detecting and reassigning the drives to the correct slots.

2 HDDs and 2 SSDs are connected directly to the mainboard.
4 HDDs are connected with an m.2 adapter card ->

I’m unaware of any files on the USB which have human readable drive assignments. With that said, you should not expect drive assignment issues with that M.2 -> SATA adapter.

 

Im pretty confident your drives will be detected and properly assigned by unraid as long as the BIOS can see all of them.

 

in the future though, definitely take note of your drive assignments (the slot and serial#) if you change hardware like a motherboard or HBA/RAID card.

usually you should be safe unless that M.2 beast is something special...

But I assume, you carry it over to the new hardware too?

If yes, connect the same drives to it again, even if special, they should be recognized as the old ones too.

For drives connected directly to the MoBo there is usally not a risk or problem at all.

So, it should just work without any stress.

 

@MAM59 & @MowMdown

I think that the controller should not cause any problems, as I have also switched the slot between the two M.2s in the past and also the last few days for testing. I have also switched the SATA connections between them and also to the mainboard and have had no problems with them in the past.

No that controller won’t cause issues. I have a similar one and it’s basically the same controller most motherboards use for extra sata ports

I have now switched to a new system.
Almost everything worked straight away.
I installed 4 new HDDs, replaced the old Parity 12TB with two 16TB and added another NVMe to the pool. Here I also caused a problem myself, which I am currently discussing in another thread.

 

Unfortunately, I didn't realize that the default configuration of new array devices has changed. (For whatever reason?)
Three of my HDDs are now formatted XFS (unencrypted).
I have now of course changed the default configuration for new devices so that future HDDs will be formatted correctly again.
The parity has already been calculated and there is still no data on the 3 new HDDs in the array.

1. is it possible to have a mixture of XFS and ZFS disks in the array or are there reasons why I should have everything in one format?
2. how can I now delete the 3 and format them again in encrypted form?
3. (Bonus): If I want to switch to ZFS and 3 HDDs are not yet formatted, can I move the data from the old HDDS with XFS to the 3 new HDDs, sofgern I have formatted them into ZFS and then format the old HDDs into the new ZFS?
