Hey list, I've got a problem with resizing a multi drive filesystem. I had a 5 disk array of 4TB drives. Then I added a 5th (6TB) drive to the array and replaced one of the 4TB ones with a 6TB drive. As you can see in my `btrfs fi sh` output below, my newly added drive (ID=6) has the expected size of 5.46TiB, but my replaced drive (ID=4) won't show up as 6TB as expected. Neither a `btrfs fi res max /data/pool0` nor a `btrfs fi res 4:max /data/pool0` had any effect. Any suggestions how to reclaim the 2TB free space of drive 4?
