From: Marcos Paulo de Souza <mpdesouza@xxxxxxxx> The first patch removes the close/open operation of stderr, so we can receive errors of balance when starting in the background. The second patch waits up to three seconds after started the balance process, to check is some problem happened to the balance process. This is done only when the user issues the "balance start" in background mode. This was tested by issuing running "btrfs balance start --background --full-balance <path>", when the balance started, issue the same command again in the same terminal: # ./btrfs balance start --background --full-balance /mnt # ./btrfs balance start --background --full-balance /mnt ERROR: error during balancing '/mnt': Operation now in progress These two patches together fixes the issue 167[1]. Please review, Thanks.
