Hi,

 

I have an array with 2 x 8TB parity drives and one of the drives in the array is on the way out and needs to be replaced. The faulty drive is currently disabled.

 

Thinking of buying 3 x 18TB drives to replace the faulty 8TB drive and the 2 parity drives. I'm just wondering which drive should be upgraded first or do I need to borrow an 8TB drive from someone?

Unclear what your current array is from your description. Sounds like you have dual parity, and maybe you also have only 2 data drives? Dual parity is typically only justified by a lot more data disks than that.

 

Diagnostics would clear this up considerably, and allow better recommendations.

 

Attach Diagnostics to your NEXT post in this thread.

The array has 12 drives. A mixture of drives, 3 of the drives need to be upgraded.

Attached are the diagnostics.

You can use the parity swap procedure.

Thanks Trurl and JorgeB.

 

I am in the process of moving all files from the emulated disabled drive using Unbalanced. The array is not even at 50% capacity so I'm wondering instead of doing a parity swap where the array will be offline for almost a day. As an alternative can I in stop the array, unassign the disabled drive and rebuild the parity drives?

If you move all the data first, you can do a new config and the not assign that drive, then re-sync parity.

I had an error showing array health report [FAIL] before the parity re-sync completed. I can't see any problems with the array. Can you please have a look at this diagnostic log.

That is normal since parity is invalid until the sync is done.
