How to Safely Shrink an Unraid Array

This video shows 2 ways to shrink an unraid array. The first way is the "Remove Drives Then Rebuild Parity" method. This method is quick and easy but does break parity. For the more cautious out there the 2nd method is the "Zero Drive Then Remove Drive" method this method is more complicated but you never loose parity. Script used in this video https://forums.unraid.net/topic/48707... For 6.12, you'll need to either modify the script or do the actual disk clear yourself (if you do it manually don't create the clear-me folder). To modify the script, search for "md${d:9}" and replace it with "md${d:9}p1" (you have to select the partition in 6.12.x). Then all the steps should work. To just do the clear part manually, run: "dd bs=1M if=/dev/zero of=/dev/mdXp1 status=progress" (replacing x with the drive number).
