How to shorten the array from 8 disks to 4

Featured Replies

My unraid was unfortunately built on a desktop chassis and it gets incredibly hot while my kids game on VM's and I stream large files. I need to move this unraid server to another chassis that can only accommodate 6 disks (4 for the usual data + 2 for parity) w/ plenty of airflow and faster NVME's. 

 

What is the easiest way to:

 

1) Delete disk 4,5,6,7 & 8 from my current array

2) Use the above to move my current array to the new chassis

3) If above is too involved - what is the cloud option you would recommend to upload all data? then wipe out current unraid and transplant disks to the new unraid chassis.

 

Any thoughts would be appreciated.

If the disks to be removed are empty then you can use Tools->New Config to reset the array to only include the drives you want to keep.   If any drive to be removed is not empty you need to first move its data elsewhere.

Thanks for this. Spaceinvader gave two options to shrink the array; i chose to zero out the drives and while it took 4 days there was no issue with parity.
