I recently added a new hard drive to my array and for some reason unRaid is not using it.  Here are screenshots of my setup:

 

 

 

 

As you can see disk 3 is not being used, even when I add more files.  In my shares it's not showing the space as being there either.  As you can see in the third image I do have the disk included.  Any idea what is wrong?

Post a screen shot of this:

 

http://tower/boot/config/share.cfg

 

(change "tower" to whatever name or IP address you've assigned to your unraid install)

Check under Settings->Share Settings

Your other two disks currently have 1.50TB used and 1.54TB used.

 

If this was the state when you added the new 3TB drive, I suspect the high-water allocation had recently "shifted" to Disk 1 (before you added Disk3).  If that's the case, it will continue to write to Disk1 until there is 250GB remaining ... and at that time will compute which drive is next.  At that point, Disk3 will be the "drive of choice" ... and will remain so until 1.5TB have been written to it.

It doesn't look like disk 3 is showing up in there.

I've had the drive in there for a little bit (before one of the drives hit the 1.5TB used) so I think it should be using it now.

 

Check under Settings->Share Settings

 

I checked there and that looks like it was the problem!  Disk 3 wasn't added.  I thought I just had to add it under the individual shares and not there.  It's showing up with the right size now so I'm sure it will start putting files there now.  Thanks everyone!

Yes, if you added it before Disk 1 crossed the 1.5TB point, Disk 3 definitely should have bee selected at that point.

 

It seems you simply didn't have it actually added to the share.

 

Just noticed that your shares show "Disk 1", "Disk 2", and "Disk 3".    I think SimpleFeatures adds the space for display purposes;  but just in case you added these via UnRAID's Web GUI, you do NOT use spaces for them in the native interface => i.e. the includes should be disk1, disk2, and disk3 (no spaces).

 

Also ... if you want your shares to use all the disks, there's no reason to have ANY includes or excludes.
