 简而言之，当您尝试在 Elasticsearch 中创建快照时，由于某些条件限制导致操作不被允许，就会发生此错误。这可能是因为集群未处于可以安全创建快照的状态，或者存储库是只读的。要解决此问题，您可以检查集群健康状况并确保其处于良好状态。如果存储库是只读的，您可以修改其设置以允许写入操作。此外，请确保用户具有创建快照所需的必要权限。
日志上下文 #  日志 “snapshot is not allowed” 的类名是 IndexShard.java。 我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入了解上下文的人参考：
final IndexShardState state = this.state; // one time volatile read  // we allow snapshot on closed index shard; since we want to do one after we close the shard and before we close the engine  if (state == IndexShardState.STARTED || state == IndexShardState.CLOSED) { return getEngine().acquireLastIndexCommit(flushFirst); } else { throw new IllegalIndexShardStateException(shardId; state; "snapshot is not allowed"); } } /** * Acquires the {@link IndexCommit} which should be included in a snapshot."

日志 "snapshot is not allowed" 的类名是 [IndexShard.java。](https://www.geeksforgeeks.org/java-lang-class-class-java-set-1/) 我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入了解上下文的人参考：

```java
final IndexShardState state = this.state; // one time volatile read
 // we allow snapshot on closed index shard; since we want to do one after we close the shard and before we close the engine
 if (state == IndexShardState.STARTED || state == IndexShardState.CLOSED) {
 return getEngine().acquireLastIndexCommit(flushFirst);
 } else {
 throw new IllegalIndexShardStateException(shardId; state; "snapshot is not allowed");
 }
 }  /**
 * Acquires the {@link IndexCommit} which should be included in a snapshot.
