Adding Precleared Disk to Array

I swear this was easier in the past, but I believe I am fighting a drive failure on one of my empty 1TB disks.. so I opted to do New Config to remove the disk and shrink the array for now.  Shortly after, I had a change of thought.  I decided to rebuild parity as well just in case.  After I decided to do that, I stopped the parity rebuild and tried adding one of my two precleared disks to an open disk slot "unassigned" - the screen just refreshed and it pops back up as "unassigned".  Is this because my parity is not yet valid?  I have access to 30 disk slots & 2 cache slots according to the configuration (and my license).

 

I realize I may have made an error, but I am just trying to figure out the correct process for adding a disk.  I understand to preclear them.  I just don't understand what UnRAID is trying to say when it refuses to attach a pre-cleared disk to an open disk slot.

 

Thanks in advance, banging my head on a wall on this one waiting for a 22-hour parity rebuild.  If that's the problem, then I'll wait obviously.

Can anyone tell me what it means when I select a disk at the array configuration (Main) tab.. with the array stopped.  Where it says Unassigned.. say, at Disk 16, I select my 2TB precleared disk.  The page refreshes and would normally say the name of the disk, but instead it refreshes and still says Unassigned rather than the name of the disk.  What does that mean?  I wish an error would appear.

Oh, this - sorry.  I overlooked this.  I will try this out when the parity rebuild is done.

 

I have a new SAS drive.  How do I get unRAID to recognize and assign it?

Why can't unRAID find or add my SAS drive?

 

Assuming you are running unRAID 6.2, go to Settings -> Display Settings and change Display world-wide-name in device ID from Disabled to Automatic.  Click Apply then Done, and then go see if unRAID will let it be assigned!

Unrelated - Is there a reason why SAS disks can't show temperature?  I've found a few other posts reporting this with no answers.

 

I believe that's a known issue, spindown probably won't work as well.

 

Ok.  Wasn't a big deal with my one SAS disk, I noticed it would refuse to spin down.  I will have 10 of them now, so I guess I will have more heat to deal with.  Is there a link to it being reported as an issue?
