My current situation: 1. Raspberry Pi 4 w/ 4 disk RAID 5 array 2. PC for general development and test. I had a 5th disk I wanted to add to the array and in the interest of making things go faster, I decided to temporarily hook up the raid array to my PC. I brought over the existing mdadm.conf settings from the Pi and the array was brought up successfully without any issue on my PC. I started the grow/reshape operation after adding the new disk and everything is going well. However, I noticed that the rebuild speed isn't that much better than what I'm used to see on the Pi. So rather than wait for the operation to complete (in a few days), I wanted to move the array over to the Pi and continue there. Can I pause/halt the reshape that's currently running on my PC and resume on the Pi? I know you can pause/halt and resume on the same system it was started on but wasn't sure if that's possible across systems when both have the same configuration settings for the raid array. Thanks for your help.
