I have a BTRFS built with two devices md0 and md1 on a server. I wish to move as much data as will fit from md0 to md1, but I cannot figure out a balance command that will do that. My use case is a file server with a fixed number of hard drive slots and two raids. md0 is a raid using most of the slots with small drives, and md1 is a raid using the remaining slots with large drives. I'm trying to shrink md0, so I can remove some small drives and put in new large drives to add to md1. I have read the notes on the balance command several times but I can't figure out how to get it to do what I want, if it's even possible. -- Stirling Westrup (he/him) Programmer, Entrepreneur. http://www.linkedin.com/in/swestrup (+1) 514-626-0928
