Forgive me, it's been a while since I've used Unraid, but I'm giving it a go again. I have a brand new setup, I have two brand new 4 TB drives installed. They are formattable via terminal commands, and unraid can see them. But even after formatting them through Unraid they continue to say "Unmountable: Unsupported Partition Format"

 

I have searched for several hours and can't find a solution. Both disks show as healthy. Is there any diagnostic data I can include to help solve the issue?

You must let Unraid format the disks from the webUI after adding them to the array.

 

attach diagnostics to your NEXT post in this thread

I added them to the array, and then format them from the Unraid WebUI, and it formats them, but they remain unmountable. I only tried to format them via terminal as a test, because they're brand new, I was curious if they could be formatted without error. I included the diagnostics and pasted the disk log information that seems to be showing it formatting them in GPT. In the WebUI it shows the filesystem as "auto"

I popped in one of my old 2 TB HDDs. It formatted and mounted no problem. I cannot figure out what the issue is here. It seems unlikely, although possible, that both of these drives have the same defect out of the box.

It's a bug with the latest release, for now suggest downgrading to v6.11.1 to format the disks, you can then upgrade back if you want.

Oh that's actually great news, easy fix then. Thank you.

 

Edit: And it worked! Thank you.
