I have several old 1 TB drives that are nearing the end of their lives and I would like to "consolidate" the data on these drives onto a single 3 TB drive.

 

I have searched and found conflicting information (seems to be the norm for unRaid).

 

Here is what I think I need to do:

 

1. purchase new drive, install and pre-clear

2. add new drive to array

3. copy data from old drives onto new drive (how?)

4. stop array

5. unassign the old disks

6. click "Restore" to create a new unRaid configuration (is this safe)

7. Start array, unRaid will generate new parity

 

Problems:  how to copy the data from the old disks to the new one?

can I simply do:

 

cp -r /mnt/disk2 /mnt/disk10

 

(where disk10 is the new drive)?

 

The purported version 5.0 manual (here: http://lime-technology.com/wiki/index.php/UnRAID_Manual_5#Restore_array_configuration) says:

 

"When the array is Stopped there is a button in the Command area labeled Restore."

Well, I just stopped my array and there is no such button there!  Does it appear if I unassign a disk?

 

Thanks for any help.

If your sig is uptodate, then you need to drop the new 3TB drive into the array as Parity first.

Parity must be as large as, or larger than any data drive.
