 简而言之，当 Elasticsearch 由于磁盘空间不足、仓库配置错误或网络连接问题而无法创建快照时，会出现此错误。要解决此问题，请确保有足够的磁盘空间并且仓库配置正确。另外，请检查 Elasticsearch 与快照仓库之间的网络连接。如果问题仍然存在，请查看 Elasticsearch 日志以获取更详细的错误消息。
日志上下文 #  日志 “snapshot failed” 类名是 RecoverySourceHandler.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的人参考：
final Engine.IndexCommitRef safeCommitRef; try { safeCommitRef = acquireSafeCommit(shard); resources.add(safeCommitRef); } catch (final Exception e) { throw new RecoveryEngineException(shard.shardId(); 1; "snapshot failed"; e); } // Try and copy enough operations to the recovering peer so that if it is promoted to primary then it has a chance of being  // able to recover other replicas using operations-based recoveries."
