[SOLVED] Disk detected by controller, but not by Unraid

[1q8448q1]

I had to replace a harddrive in my Unraid Server and so I attached a new Seagate SAS-Drive. It's correctly connected and the config-utility of the SAS-controller does detect the drive. (see picture, it's the one in Slot 6) Unfortunately though Unraid does not detect the drive and I can not assign it in the webui.

 

What could be the solution here? Thank you for your support!

sdc and sde are the drives in slots 5 & 7

 

Does anybody know what difference is between the "0003" and the "MS0F" as shown in the controllers config utility?

You should post your system’s diagnostics zip file (obtained via Tools -> Diagnostics) so we can see what is going on and give sensible feedback.

The problem is that the SAS disk currently has an a sector size of 520 which is not supported.     You should be able to find forum posts that give the steps required to reformat to a supported sector size.

Thank you! I found this post:

And I am currently trying to format the drive with sg_format, which seems to take quite some while.

I would expect it to take some time as I think it has to write to every sector on the drive.

Yes I took all night for this 4TB drive.

 

But now it has successfully finished and Unraid showed the new disk after a reboot! Parity rebuild has started.

 

Thank you very much for your kind help @itimpi
