No way to fix this unmounted. To: linux-btrfs@vger.kernel.org Cc: Jesse Emeth , Qu Wenruo Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Sender: linux-btrfs-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-btrfs@vger.kernel.org Hi Qu How old a kernel needs to be used to "work around this by using an older kernel to finish the balance, and then repair.(due to relocroot is a special corner case I didn't take into consideration)? What version of btrfs-progs/tools should be used in this case? Also the problem as mentioned in this thread is that the volume cannot be mounted rw. Are there versions of balance that can work on unmounted devices? Or is this now another catch 22 problem where balance is required to enable rw mount but rw mount is required to balance? Are there really not any manual dev tools where a specific directory and its referenced inodes can be manually specified for foremoval?
