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.
