根因分析
同一仓库已有快照操作正在进行中，默认情况下 Elasticsearch 不允许对同一仓库执行并发快照。
English
A snapshot operation is already running for the same repository, and Elasticsearch does not allow concurrent snapshots to the same repository by default.
官方文档
https://www.elastic.co/guide/en/elasticsearch/reference/current/snapshots-take-snapshot.html解决方案
-
Check the current snapshot status and wait for completion: GET _snapshot/my_repo/_current
-
Abort the running snapshot gracefully: POST _snapshot/my_repo/snapshot_name/_cancel
-
Increase the snapshot timeout to allow longer operations: PUT _cluster/settings { "persistent": { "snapshot.max_concurrent_operations": 2 } } (requires Elasticsearch 8.0+)
无效尝试
常见但无效的做法:
-
80% 失败
Deleting an in-progress snapshot may cause repository corruption or leave partial data. It is not recommended.
-
95% 失败
Snapshot state is persisted in the repository metadata, not just memory. Restarting nodes does not release the lock.
-
60% 失败
This does not resolve the conflict for the original repository; it only creates a workaround that may not be feasible for production.
