+# Overlap validation and repair tool
+
+The Overlap Validation And Repair tool is used to validate the resource files in sequence space, and repair overlaps.
+
+The validation function can be run in any scenario. Confirmation is required after overlapping files are found. Typing 'y' will perform the repair.
+
+**The repair function must be run when corresponding DataNode is stopped and there are no unfinished compaction task in all data dirs.**
+To make sure there are no unfinished compaction tasks, you can modify the config files to set enable compaction items to false, and restart DataNode waiting compaction recover task to finish.
+Then stop the DataNode and run this tool.
+## Usage
+```shell
+#MacOs or Linux
+./check-overlap-sequence-files-and-repair.sh [sequence_data_dir1] [sequence_data_dir2]...
+# Windows
+.\check-overlap-sequence-files-and-repair.bat [sequence_data_dir1] [sequence_data_dir2]...
+```
+## Example
+```shell
+./check-overlap-sequence-files-and-repair.sh  /data1/sequence/ /data2/sequence
+```
+This example validate two data dirs: /data1/sequence/, /data2/sequence.

+# Overlap validation and repair 工具
+
+Overlap Validation And Repair 工具用于验证顺序空间内 tsfile 的 resource 文件的重叠情况并进行修复。
+
+验证功能可以在任意场景下运行，在找出所有存在重叠的文件后，需要输入 'y' 以确认是否进行修复。
+
+**修复功能必须在相关的 DataNode 停止之后执行，且对应的数据目录中不存在未完成的合并任务。**
+为了确保没有尚未完成的合并任务，你可以修改配置文件中开启合并相关的配置项为 false，然后重启 DataNode 并等待合并恢复任务的完成，停止 DataNode，再运行这个工具。
+## 使用方法
+```shell
+#MacOs or Linux
+./check-overlap-sequence-files-and-repair.sh [sequence_data_dir1] [sequence_data_dir2]...
+# Windows
+.\check-overlap-sequence-files-and-repair.bat [sequence_data_dir1] [sequence_data_dir2]...
+```
+## 示例
+```shell
+./check-overlap-sequence-files-and-repair.sh  /data1/sequence/ /data2/sequence
+```
+这个示例指定了配置的两个数据目录进行扫描: /data1/sequence/, /data2/sequence。
