...rs with "btrfs scrub status" while scrub is running - effective locking to protect against multiple scrubs on a filesystem - man page entry for scrub added Change log v2->v3: - unverified_errors counter added - return code of utility now depends on detected disk errors - bail out when check_mounted_where returns an error - changes as suggested by Hugo Mill''s review. incomplete list: - style (checkpatch is happy now) - pthread_* error handling - use /var/lib/btrfs instead of /var/btrfs for storing history Attention: This version may be useful for Hugo, only.
