根因分析

Elasticsearch进程缺少对事务日志文件的写入权限，通常由于文件系统权限更改或磁盘错误引起。

English

The Elasticsearch process lacks write permissions to the translog file, often due to filesystem permission changes or disk errors.

解决方案

  1. 修复事务日志目录的权限：chown -R elasticsearch:elasticsearch /data/elasticsearch/nodes/0/indices/ 并确保elasticsearch用户有写权限。
  2. 如果磁盘满，通过删除旧索引或增加磁盘容量释放空间，然后重试同步。
  3. 作为最后手段，关闭并重新打开索引以重新生成事务日志：POST /my_index/_close 然后 POST /my_index/_open。这可能会丢弃未提交的更改。

无效尝试

常见但无效的做法:

  1. 90% 失败

    The underlying permissions issue persists; the node will fail again when it tries to sync the translog.

  2. 70% 失败

    Deleting translog can cause data loss and corrupt the shard; Elasticsearch may refuse to start.

  3. 50% 失败

    The new directory may also have permissions issues if not configured correctly.
