Validators in this mode will gossip their last \\\n vote to reach consensus on a safe restart slot and repair all blocks \\\n on the selected fork. The safe slot will be a descendant of the latest \\\n optimistically confirmed slot to ensure we do not roll back any \\\n optimistically confirmed slots. \\\n \\n\\n\\\n The progress in this mode will be saved in the file location provided. \\\n If consensus is reached, the validator will automatically exit with 200 \\\n status code. Then the operators are expected to restart the validator \\\n with --wait_for_supermajority and other arguments (including new shred_version, \\\n supermajority slot, and bankhash) given in the error log before the exit so \\\n the cluster will resume execution.
