问题

  • AIQUM 中一个集群的集群发现卡住,显示运行状况轮询状态正在进行中
  •  新添加集群的初始发现从未完成
  • 记录下的 au.log /log_netappfoundation_<cluster_IP>_<DS_ID>_<Date_and_time>_xxx_sample.log 显示正在尝试初始发现的 [netappfoundation] <New_CLUSTER IP> - while executing ZAPIs on datasource: <CLUSTER IP> IP: <CLUSTER IP> for ZAPI: <ZAPI>, java.io.EOFException集群的
  • log_netappfoundation_xxxx_iterator_response_time.txt 下现有集群基础轮询记录中不同 ZAPI 调用的大量执行时间和返回记录
  • 一些表现出此行为的已知 ZAPI 调用包括:
  • job-schedule-get-iter
  • job-schedule-cron-get-iter
  • quota-report-iter
  • qtree-list-iter
  • snapmirror-history-get-iter
  • 错误示例:
datasource, zapi, timestamp, max-records, iterations, total-clock-time, total-zapi-time, total-invocations, total-records, returned-records-list
