| - 如果无正常返回，请执行 `SELECT * FROM information_schema.tiflash_replica` 检查是否已经创建 TiFlash replica。如果没有，请重新执行 `ALTER table ${tbl_name} set tiflash replica ${num}` 或者查看是否有其他执行语句（如 `add index` ）或 DDL 操作是否异常。 |

“查看是否有其他执行语句（如 add index ）或 DDL 操作是否异常” 这句有点不通顺，请看看要不要调整下
tiflash/troubleshoot-tiflash.md
Outdated
| - 没有更新，检查下一步； | ||
| - 有更新，检查是否有 `down peer` （`down peer` 没有清理干净可能会导致同步卡住） | ||
| - `pd-ctl region check-down-peer` | ||
| - `pd-ctl operator add remove-peer\<region-id> \<tiflash-store-id>` |

这里的步骤是这样的吗？ 1。 执行 pd-ctl region check-down-peer 命令检查是否有 down peer。2. 如果检查出来有 down peer，执行pd-ctl operator add remove-peer\<region-id> \<tiflash-store-id> 清除 down peer.
