根因分析

别名被配置为引用一个已被删除或不存在的索引，导致对别名的操作失败。

English

An alias is configured to reference an index that has been deleted or does not exist, causing operations on the alias to fail.

解决方案

  1. 更新别名指向现有索引：POST _aliases { "actions": [ { "remove": { "index": "logs-2025.03", "alias": "logs_current" } }, { "add": { "index": "logs-2025.04", "alias": "logs_current" } } ] }
  2. 如果索引被意外删除，从快照恢复：POST _snapshot/my_repo/snapshot_2025/_restore { "indices": "logs-2025.03", "rename_pattern": "logs-2025.03", "rename_replacement": "logs-2025.03" }

无效尝试

常见但无效的做法:

  1. 70% 失败

    If the mapping does not match the expected schema, the alias may work but queries fail; also, data from the original index is lost

  2. 95% 失败

    The alias still references the missing index; it must be updated to point to an existing index
