Hello together,

 

a fews days ago I saw a dead drive on the array (red x). I ordered a replacment drive which I received today. Than I did the following:

 

1. Powered down the server 

2. Switch drive

3. Start server

4. Assign new drive

5. Selecte rebuilt

 

For some reason the system stalled and showed 'Unknown' for finishing time and 'Paused' at the bottom left of the screen (also almost no writing to replacment disk). So I had to reboot the system.

 

Now it only shows the 'Start will bring the array' online. I doesn't mention anything of rebuilding the arry.

 

What can I do?

 

Btw.: The connection between drive and board looks good.

You are likely to get better informed feedback if you attach your system’s diagnostics zip file to your next post in this thread. It is always a good idea when asking questions to supply your diagnostics so we can see details of your system, how you have things configured, and the current syslog.

Drive 18 is the new replacment drive.

Write failed during the rebuild, check/replace cables or swap slots and try again.

Changed the cable and moved the port from the add-on card to the mainboard. I started the array and it still says "Start will bring the array online" and nothing of rebuild.

That would be expected if the drive currently shows as disabled (which is likely if you got a failure in the previous rebuild attempt).

In such case you need to follow the procedure outlined here in the online documentation accessible via the Manual link at the bottom of the Unraid GUI.

Okay. That is a lot of text.

 

I can't go any further form the present screen with 'Start will bring the array online'. So I should start maintenance mode and do a parity check/rebuilt?

 

(optional) Tick the box to start in Maintenance mode. If you start the array in Maintenance mode you will need to press the Syncbutton to trigger the rebuild. The advantage of doing this in Maintenance mode is that nothing else can write to the array while the rebuild is running which maximises speed. The disadvantage is that you cannot use the array in the meantime and until you return to normal mode cannot see what the contents of the disk being rebuilt will look like.

 

Drive18 shows indeed as disabled / emulated data...

You need to follow the steps outlined in the link I gave.   For instance the first step is NOT to start the array but to unassign the disabled disk.

Thanks!! It is rebuilding now. I guess the cable is dead or the port on my SATA add-on card.
