适用场景

  • ONTAP 9
  • 自动化无中断更新(ANDU)
  • FlexCache
  • SVM灾难恢复(SVMDR)

问题描述

  • FlexCache初始卷位于受影响的集群上、Vserver可以是R/W初始卷、也可以是DP初始卷:

cluster1_origin::*> vol flexcache origin config show
Origin-Vserver   Origin-Volume    Is-BLI-Enabled  Is-Global-File-Locking-
                                                  Enabled
---------------  ---------------  --------------  --------------
svm_origin       vol_origin       false           false

  • 在FlexCache原始集群上执行FlexCache回写检查时、ANDU预检查验证失败、并显示错误:

There are one or more FlexCache volumes with writeback option enabled pointing to the origin in this cluster.

  • 如果在对等FlexCache缓存集群上验证FlexCache卷、则会显示回写已禁用:

cluster3_cache::*> volume flexcache config show -fields is-writeback-enabled
vserver   volume    is-writeback-enabled
--------- --------- --------------------
svm_cache vol_cache false

  • FlexCache初始卷的SVMDR关系已存在或已存在、但此关系仍处于或在过去某个时间已断开。
  • 受影响的集群可以是SVMDR源集群、也可以是目标集群。
