Reusing a old Unraid Drive

Featured Replies

I recently upgrade 2 3TB drives to 6TB

I replace 1 drive at a time and let it rebuild each time (~10hrs) each

 

After that pool was up and running I tried to install the two old drives so that I could create a new pool for IP_camera storage.

The old drives would not show up in Unraid even after reboot.

 

I hooked the drives up to a windows machine and the drives were detected it showed up 3 times in disk manager

example (Disk 3, Disk  3, Disk 3)

 

I ran Seagate's Drive tools to check the health of the drive and everything came back good.

 

Any thoughts? 

These are old drives from 2014 so they might have just crapped out.

It looks like the issue was the top bay some of the STAT tables were not clipped in and i guess didn't make proper connection.

The drives are showing up now. I just need to clear them.

Ok, I'm up and running just like I wanted too.

I had to open terminal and rebuild the partition tables on each drive.

 

Open Terminal

parted /dev/sd?                 sd? = the drive your targetting like sdh or sdg

select /dev/sd?                  make sure drive is selected

mklabel gpt                        y  = to confirm

 

That made the drives available for preclear.

 

One other note,

In order to have drives slots show up under the new pool you need to change the pool size of your main array so instead of 22 -> 12

This allowed me add the 2 new/old drives to the newly created pool.
