Hi all,

 

For a while now I've been trying out Unraid. Initially it seemed to work just fine. However the idea was scrapped and I started over again. Now I have a new machine, where I added a 14TB drive. I wanted to use that as only data disk (with no other disks) so I can copy over my data and add the other (pairity) drive later.

 

Anyway I start up my array with the disk as first data disk and I'm fine with formatting it. However it just fails to do so. The logs show me this:

For some reason it keeps getting the non-matching super-block. I can't figure out why.

For complete info I got the diagnostics too. Just need to find a way of adding them to the post...

There are disk errors even before attempting to format, try connecting the disk to the onboard SATA controller to see if there's any difference

I think that's reading the super-block, but I'll see if I can mend that.

So the on-board sata-connector does work!

How's that possible? I used the same controller as before, just that I had 4TB disks.

There could be some compatibility issue with the HBA and that disk model.

damn and blast!

That throws in another spanner, a rather big one, in my plans.

Is this another plugin in addition to the unassigned that I have?

Yes.
