Good morning:

Did some searching around and saw some posts about "unmountable disks" but nothing like what I'm experiencing.  All the ones I saw had to do with replacing failed disks, upgrading disk size, etc.

For me, though?  It's a brand new disk!  I put a brand new disk in, it cleared and all that, now it says "unmountable".  



I don't get it...why would a brand new disk be "unmountable"?  Any help greatly appreciated.  Never had this happen.  Usually I just shove a disk in, it clears and away we go...

I assume because you haven't yet formatted it, so it has no filesystem to mount.

after formatting it in the array, right?

 

Or am I wrong with all this and you have already put files on the disk?

Nope...there isn't anything on it.  I took it out of the box and shoved it in the server.  I don't remember having to do anything else with it before...pretty sure I just put it in, add it to the array, it clears, bob's your auntie.  I'm not even sure off hand how to format a disk in unRAID.  lol

In looking for how to format a disk, I came across this:

"You dont need to "format" disks to add them to an array. UnRAID will automatically preclear the disk, format and bring it online when you configure the array."

This is how I remember it, too.

That link is to an old article that isn't even on this website.

There is a basic misunderstanding here.

 

At the bottom of the main GUI there should be a checkbox and dialog to initiate Unraid's formatting of any unformatted disks in the array.

 

The piece that you quoted assumes you would check that box and allow Unraid to do its thing.

 

If you format a drive BEFORE adding it to a parity protected array it will be erased anyway, so no need (or use) to format a drive before adding it. You must let Unraid do the formatting after you add it.

Guess I'm going to have to stop the array again and see if there's a "format" button somewhere.  Don't remember having to do that before but that's the only thing I can think of.  I can't stop the array right now as I have things going on on the server that I have to wait for.  Will give it a shot and let you all know how it goes.

You can't format the drive while the array is stopped.

You can format the disk with the array started.

Thank you...took me forever to figure that out.  I was expecting the format option to be next to the drive in "Array Devices", or on the "Disk Settings" tab.

WOW... Reading this threat was like somekind of Fast-Forward from the TV series LOST.  I agree with comments above, I was expecting the format option to be with the new HDD. IMO, the current implementation is not intuitive or logical. Just my feedback, not something worth debating.
