Description

三节点集群的TDEngine数据服务器，其中一个节点硬盘满了，写入数据报No enough disk space，尝试备份数据之后删除部分旧数据，备份数据成功，之后使用delete from his_data where ts<’2025-05-01 00:00:00.000';报错误No enough disk space，数据删除失败，请问这种情况下改如何修复？

Contributor guide

Research direction
Investigate how TDengine handles DELETE operations; they may require free space for compaction. Try freeing up disk space by removing logs or using the system's purge feature. As a last resort, expand the disk volume or use data export/import.
