COTTP-54204：在ONTAP 9.8中、由于间歇性校验和不匹配、涉及温度敏感型存储效率(TSSE)卷的SnapMirror传输可能会失败
问题描述
- 此错误仅适用于SnapMirror源集群在纯闪存FAS (AFF)集群上运行ONTAP 9.8的适用场景系统
- 传输某些数据后、SnapMirror传输失败并显示错误：
Transfer failed. (Checksum mismatch(Replication engine error)) - 如知识库文章中所述、网络上没有问题：SnapMirror传输失败、并出现校验和不匹配或未整理错误
- 目标集群传输会在重试8次后失败(SnapMirror策略的默认值)。每次重试时、都会向目标传输一定数量的数据
- SnapMirror审核日志(
/etc/log/snapmirror_audit)指示以下内容：Wed Oct 13 14:52:22 UTC 2021 Initialize[Oct 13 14:51:06]:Operation-Uuid=<operation_uuid> Group=none Operation-Cookie=0 action=Defer source=<source_path> destination=<destination_path> status=Failure message=Transfer failed.(Checksum mismatch(Replication engine error)) - 在源集群上、EMS日志(
/etc/log/ems或event log show命令)指示：
repl_Handle_low: repl.engine.error:debug]: params: {'replFailureMsgDetail': '5898509', 'lineNumber': '671', 'replFailureMsg': '5898522', 'functionName': 'virtual void repl_stream::DataSource::DataContext::spinnpResponse(repl_spinnp::Request &, repl_spinnp::Response &)', 'replStatus': '14'}- 同样在源上，SKTrace日志(
/etc/log/mlog/sktrace.log)指示：
