Hi there, I am new to Unraid, apologies for newb q's.

The system

I had a TRAID configuring in Terramaster TOS 6. The NAS is NVME drives only, 8 x 4TB Samsung 990 EVO Plus.

I make the recommended BIOS changes to boot drive, secure boot, and VT-d.

I created a flash install and booted the system with no changes to Unraid 7.1.4.

I have connected to the NAS via tower.local and am on the Main tab. I have a Kingston flash drive externally in the USB port for use as a dummy array disk. I intend to have all NVME drives in the Pool.

No Disk 1 appears under Array Devices, nothing is in Slots.

The Array Operation shows the array as Stopped. I have never configured an array in Unraid, I am assuming this is an error perhaps it is seeing some info from the TRAID array it was configured as.

What have I tried to do to fix

I have gone to Tools and New Config. I have tried to reset the array disk config, this does not do anything I can see.

I have rebooted after doing New Config, even though I was not prompted to do so.

Stuck. I am an hour into this and not making progress. Google Gemini was pretty helpful so far, but troubleshooting has stalled after new config.

Ideas? I have attached a screenshot of System Devices under Tools. Also a screenshot of main tab for clarity.

Thanks!

With BIOS changes, it is recommended to have secure boot off. But as it appears, your in the unraid interface. I say you're doing well.

Is this the first time booting into unraid?

As unraid doesn't auto add devices to the array / pool for configuration. You build that:
https://docs.unraid.net/unraid-os/manual/storage-management/

Is there data on the nvme SSD that you're trying to save?

As You appear to be at the first step of disk creation. You may need to make a new pool of devices and set up a grouping of disk to use them on unraid...

Example a grouping of 3 setup as zfs raidz1 for xyz application.

You will need to decided if all disk need formatted (Loos data on them) and be made into a unraid box.

Then decide on what file system you want and how you want to handle the disk.

given that you have 8 nvme I would recommend a zfs pool

https://forums.unraid.net/topic/177887-os-70beta4-best-practice-storagediskcache-configuration/

BUT if they have data on them, you want saved, we need to move data off the drives first. And configure a grouping of disks

as your 8x 4TB disks

can easily become

4x 4TB mirror pools having 4 4tb volumes to work with or

2x 4TB raidz2 (10 ish TB where you can lose 2 nvme and still have all data)

or any other combination that will suit your needs for setup...

What are you planing to do with unraid on this device?

VMs, Dockers? General NAS duties?
Review: https://docs.unraid.net/unraid-os/manual/shares/user-shares/#default-shares

As disk setup here can impact latter. Are you looking to expand storage? This may affect how you want to set up the disks

Then you need to come up with a folder hierarchy system.

xyz folder exist where and what is written to it.

How do you want to interact with it, and what do you want it to do?

right now your under the new config sytem setup

if you want the unraid traditional array Disk 1, Parity, disk 2 etc you need to set the Array Slots # from none to something else
This may require formatting the disk and use xfs file system.

otherwise you need to hit add pool call it something like cache
and also set the slots # of disks...

this by default will format them as btrfs.

if you want zfs it must be a pool device only you click the name and select the file system typ to zfs depending on the slot number and select zfs raidz1 1 vdev

If this was a previous unriad with data on disk you may need to set the slot placing the correct disk where it was before and setting the File system to auto to detect the previous data on disk.

Seems to be a proprietary filesystem, i.e. you probably won't be able to use it un unraid or any other OS than theirs without wiping all drives.

TNAS uses the EXT 4 or Btrfs file system, please check the official specification on there website... I have messed with theses before in the past...

The unraid unassigend disk plugin will work to connect and see the data on disk. Any linux distro will be able to mount and few. If they were raided and using LMV it may be a bit harder outside of the Tnas OS...

as such all data on the device from the previous is most likely in a mdadm linux software raid setup...

TerraMaster's TOS 6 also features TRAID, which is a dynamic RAID technology. TRAID allows for flexible expansion of storage space by adding or replacing hard drives of different capacities. When creating a TRAID array, the file system (ext4 or Btrfs) is used to manage the storage. (Similar to how unraid handles the standarad array of disks.)

• TRAID:

  A TerraMaster-specific RAID technology that leverages either ext4 or Btrfs for data storage and provides flexibility in disk management. 

As they hit new config and other, I believe this was formatted original as unraid as they are using AI. regardless, data needs to come off some disk and be reformatted to work with another OS.
