I am attempting to enlarge my Btrfs partition. Every time I run "btrfs filesystem resize max $MOUNT", the command runs for a few minutes and then hangs forcing the system to be reset. I am not sure what the state of the filesystem really is at this point. Btrfs usage does report the correct size for after resizing.
