Over the starter device limit - does the boot USB count? or is it my configuration.

Featured Replies

So I have the starter Licence.

I have 4 HDDs (3 drives, 1 parity), 1 NvMe as Cache, and the Usb with Unraid on it.

I've attached a 2nd NvMe for Cache, and I'm getting the unraid device limit.

Does the Usb count towards the limit? The other issue I have which ive never been able to figure out is in the Array size, the minimum i can select is 5 (cant go below 5), with 2 parity (1 of which ive left unassigned), and 3 disk drives.

Is the problem the USB? or is it that the array size is 5 and counting it as such, even though i only have 4 drives there)?

Nope, but there's another connected, and that one counts.

Thing is I only have the one usb connected, the usb drive with unraid in it. I have no idea where this is. I'm using a Terra master f424.

EDIT: Found the reason. theres an internal Terramaster TOS USB.

Sometimes devices like (USB) network cards, CD Roms and so on contain a 2nd partition shipping the needed drivers for that card.

Usually this is turned off once you have installed it under windows. This will obviously not work with UNRAID/Linux.

So there may be an additional drive that you are not aware of.

Check the USB devices.

(Aaah, also certain KVM devices like NANOkvm come with an storage device which allows you to flash bios or ship drivers. Usually you can find a setting to turn this off)

Also there is a chance that the "device" is fixed build into your terramaster. Maybe you should take a look if the "disc" is mountable and contains valid files (the filenames may help to find out where it belongs to)

You should be able to drop that device offline, but it would need to be done after every reboot:

echo 1 > /sys/block/sdX/device/delete

Better check out the culprit and try to fix it completely...

@JorgeB 's "Fix" clears it but I think it is really dangerous considering that UNRAID often "renumbers" sdX names after updates and so on.

This can lead to serious troubles if you have forgotten the line until then and sadly see one existing disk with data "vanishing" (its not gone or deleted, but "shut off" unless you edit the mentioned line and correct it).

Definitely don't put that in your go file.

You need to reevaluate X after boot has finished, then execute it. So this means you can't autostart the array.

first find out what this additional device is and then we may find a way to (safely) get rid of him...

Probably need to either disconnect it if it's a physical USB or disable it in BIOS so unraid does not detect it
