Hi @dsilletti, We really appreciate for discovering this bug and your active reply for helping us to locate the root cause. In short, your data are safe yet the ConfigNodes have deleted prior [data partition table](https://iotdb.apache.org/UserGuide/latest/Technical-Insider/Cluster-data-partitioning.html) unexpectedly. This issue occurs when you employ the tree schema mode as well as config only the device-level Time to Live (TTL). The affected versions are [1.3.2, 1.3.6] and [2.0.5, 2.0.6]. We have addressed this fatal bug in [this](https://github.com/apache/iotdb/pull/17123) PR, and welcome to click and review the correct data partition table expire rules. To avoid subsequent data partitions being deleted incorrectly, try: 1. Compile the master branch of Apache IoTDB and upgrade the version of your ConfigNode; or 2. Waiting for the release of version 1.3.7/2.0.7. The release is in progress, I believe we will done this before Feb. 10. To recover your data partition table: 1. Stop your current IoTDB cluster. 2. Deploy a new IoTDB cluster with correct version of ConfigNode. 3. [Load all TsFiles](https://iotdb.apache.org/UserGuide/latest/Tools-System/Data-Import-Tool_apache.html) from your previous IoTDB cluster. @dsilletti Thanks again for helping us tackle this fatal issue. @ruizdiazever Please check this if it is helpful for resolving your issue. I will close this issue after our next release, if requires no further discussions. Best regards, Yongzao -- This is an automated message from the Apache Git Service.
