Besides fail_at_unmount, all EIO error handling can stop umount hanging on IO error too. This case test EIO/max_retries and EIO/retry_timeout_seconds as below: 1) fail_at_unmount=0 && \ EIO/max_retries=1 && \ EIO/retry_timeout_seconds=0 2) fail_at_unmount=0 && \ EIO/max_retries=-1 && \ EIO/retry_timeout_seconds=1 Make sure when fail_at_unmount=0, umount won't hang there.
