适用于

  • Microsoft Azure
  • Cloud Volumes ONTAP (CVO)
  • High Availablity (HA)
  • ONTAP 9.9.1, 9.10.0
  • 未同步的日志
  • 非计划接管失败

问题

在 Azure CVO HA 上,将 ONTAP 升级到 9.9.1 或 9.10.0 后,客户看到错误消息 takeover of <NODE> disabled (unsynchronized log).

EMS.log:

Sun Jan 00 00:00:00 +0000 [AzureCVOHA-01: cf_main: cf.fsm.takeoverOfPartnerDisabled:error]: Failover monitor: takeover of AzureCVOHA-01-02 disabled (unsynchronized log).
 

原因

Bug 1470622 Mismatch in the CRC check might result in the takeover becoming temporarily disabled
 
高可用性 (HA) 虚拟机 (VM) 接收端的循环冗余校验 (CRC) 可能会导致其中一个或两个 VM 暂时禁用接管。
 
SKTRACE.GZ:
0000-00-00T 00:00:00Z 4159002023081836 [9:0] SIW_ERR: siw_check_crc: LINE:1785 op=SIW_WR_RDMA_WRITE CRC ERROR in:=de74e35d, own=b3b866a8

解决方案

一旦可用,请升级到错误修复版本。
 
注意:
  • 出现此问题时,未同步的日志会自行重新同步,并自动重新启用计划外接管。
  • 当由于日志未同步而禁用接管时,通常会持续 10-35 秒。
  • 计划内接管(作为 ONTAP 升级的一部分,Azure 维护事件 - 冻结、NIC 分离、用户触发)工作正常。

追加信息

Bug 1463141  - Mismatch in the CRC check on Azure HA VMs might result in the takeover becoming temporarily disabled 跟踪所有崩溃的非生产版本。
 

内部参考

P Patch Request # 10217 已针对 ONTAP Bug1463141 提交,请求将修复回移至 9.9.1P10(预计 2022 年 6 月 24 日)和 9.10.1P5(预计 2022 年 6 月 27 日)
