适用场景

  • ONTAP 9.8
  • 纯闪存 FAS ( AFF )
  • SnapMirror

问题描述

  • 只有当 SnapMirror 源集群在纯闪存 FAS ( AFF )集群上运行 ONTAP 9.8 时,此知识库才适用
  • 传输一定数量的数据后,初始 SnapMirror 传输失败并出现错误:
     Transfer failed. (Checksum mismatch(Replication engine error))
  • 如以下知识库文章所述,网络上没有问题

SnapMirror 传输失败,并出现校验和不匹配或取消组织错误 

  • 在目标集群上,在重试 8 次后,传输失败( SnapMirror 策略的默认值)。每次重试,都会将一定数量的数据传输到目标
  • 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/emsevent 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'}
 
  • 此外,在源上, SK跟踪 日志(/etc/log/mlog/sktrace.log)也表示:
REPL_0: repl_spinnp::Session::_handleNextCsmResponse(): | [ddd94d44-1f77-11ec-a7ea-00a098d92444] | [0xffffffff948466f0] result: [status: 91 failure_msg: 5898741 failure_msg_detail: 4063303] received response with error from CSM. csm error: 71 request major op: 7 request minor op: 24from b8e42de7-38fd-11e9-aa37-00a098d92444,f7ea4ced-38fb-11e9-aa37-00a098d92444 at b4775206-cb19-11eb-b63f-d039ea499ab4
