Hi,

 

Appreciate confirmation of the following before I actually do it.

 

I added a new (old) drive yesterday that I had lying around. It basically failed this morning, so I want to simple remove it and carry on whithout it.

 

If I understand correctly I can do the following

 

1 - Stop the array

2 - Unassigned the faulty disk

3 - Click restore button

 

And the array will re-initialise with remaining disk and most importantly keep all my data!

 

I have no data on the new drive and have no desire to replace it yet as I have load sof space.

 

I just need to confirm that the restore data will not impact my existing data on the good disk.

 

The last parity check was run yesterday morning (probably irrelevant)

 

Thanks

 

Matt

You are correct.  The use of the "restore" button after un-assigning a unwanted drive will rebuild parity on the remaining drives in the array.  The data on those other drives will not be impacted, other than there will not be parity protection until the parity build process is completed.

 

It is good you verified that the other disks are working by performing a parity check recently. (so it is relevant)

 

Pressing the button labeled "restore" will rename the config/super.dat file on your flash drive, effectively removing it.  When you then "Start" the array, unRAID will then create a new super.dat file based on the assigned and working drives (why it is important to ensure the others are all working) and then set upon calculating a completely new set of parity data and storing it on your parity disk, as the old calculations are meaningless with the old disk removed.

Thanks Joe - really appreciate the quick reply, I can get this underway now.

 

Always best to check in these situations.

 

Serves me right for gamlbing on an old drive, the others are all new.

 

Thanks again
