[6.9.2] [SOLVED] Adding drive to array "Disk in parity slot is not the biggest."

Featured Replies

Hi All,

 

I seem to be unable to add a new drive to my array, even though they are all the same size.

The drives are all 2TB, and everywhere I look they are reported as exactly the same size.

 

What I've tried (which didn't work!)

- Re-formatting the drive

- Re-seating the drive

- Checking the "HPA" status - disabled on all drives

I've attached some screenshots and the system diagnostics - anyone got any ideas?

 

Array of 3 drives

That is the problem, parity partition starts on sector 2048, so it's smaller than the other one, normal starting sector for Unraid is sector 64 (except for non rotational devices), so you'd need to wipe parity first and let Unraid repartition it.

  • Author

That’s really strange, the parity was wiped by Unraid so not sure why it was setup non-standard.

 

What’s the easiest way to reinit the parity?

  • Community Expert

Erase current partition with fdisk and let Unraid recreate it, you'll need to re-sync parity.

Thanks JorgeB - this worked and now have added the other drive in as well.
