在 MetroCluster 配置中移动元数据卷
贡献者
建议更改
您可以将元数据卷从 MetroCluster 配置中的一个聚合移动到另一个聚合。如果源聚合已停用或未镜像,或者由于其他原因使聚合不符合条件,您可能需要移动元数据卷。
关于此任务
-
要执行此任务,您必须具有集群管理员权限。
-
目标聚合必须已镜像,并且不应处于已降级状态。
-
目标聚合中的可用空间必须大于要移动的元数据卷。
步骤
-
将权限级别设置为高级:
set -privilege advanced
-
确定应移动的元数据卷:
volume show mDV_CRS*
Cluster_A::*> volume show MDV_CRS* Vserver Volume Aggregate State Type Size Available Used% --------- ------------ ------------ ---------- ---- ---------- ---------- ----- Cluster_A MDV_CRS_14c00d4ac9f311e7922800a0984395f1_A Node_A_1_aggr1 online RW 10GB 9.50GB 5% Cluster_A MDV_CRS_14c00d4ac9f311e7922800a0984395f1_B Node_A_2_aggr1 online RW 10GB 9.50GB 5% Cluster_A MDV_CRS_15035e66c9f311e7902700a098439625_A Node_B_1_aggr1 - RW - - - Cluster_A MDV_CRS_15035e66c9f311e7902700a098439625_B Node_B_2_aggr1 - RW - - - 4 entries were displayed. Cluster_A::>
-
确定符合条件的目标聚合:
MetroCluster check config-replication show-aggregate-eligibility`
以下命令标识 cluster_A 中符合托管元数据卷条件的聚合:
Cluster_A::*> metrocluster check config-replication show-aggregate-eligibility Aggregate Hosted Config Replication Vols Host Addl Vols Comments ------------ ------------------------------------------ -------------- -------- Node_A_1_aggr0 - false Root Aggregate Node_A_2_aggr0 - false Root Aggregate Node_A_1_aggr1 MDV_CRS_1bc7134a5ddf11e3b63f123478563412_A true - Node_A_2_aggr1 MDV_CRS_1bc7134a5ddf11e3b63f123478563412_B true - Node_A_1_aggr2 - true Node_A_2_aggr2 - true Node_A_1_Aggr3 - false Unable to determine available space of aggregate Node_A_1_aggr5 - false Unable to determine mirror configuration Node_A_2_aggr6 - false Mirror configuration does not match requirement Node_B_1_aggr4 - false NonLocal Aggregate
在上一示例中, Node_A_1_aggr2 和 Node_A_2_aggr2 均符合条件。 -
启动卷移动操作:
volume move start -vserver svm_name -volume metadata_volume_name -destination-aggregate destination_aggregate_name*
以下命令将元数据卷 "mdv_CRS_14c00d4ac9f311e7922800a0984395f1" 从 "aggregate Node_A_1_aggr1" 移动到 "aggregate Node_A_1_aggr2" :
Cluster_A::*> volume move start -vserver svm_cluster_A -volume MDV_CRS_14c00d4ac9f311e7922800a0984395f1 -destination-aggregate aggr_cluster_A_02_01 Warning: You are about to modify the system volume "MDV_CRS_9da04864ca6011e7b82e0050568be9fe_A". This may cause severe performance or stability problems. Do not proceed unless directed to do so by support. Do you want to proceed? {y|n}: y [Job 109] Job is queued: Move "MDV_CRS_9da04864ca6011e7b82e0050568be9fe_A" in Vserver "svm_cluster_A" to aggregate "aggr_cluster_A_02_01". Use the "volume move show -vserver svm_cluster_A -volume MDV_CRS_9da04864ca6011e7b82e0050568be9fe_A" command to view the status of this operation.

验证卷移动操作的状态:
volume move show -volume vol_constituent_name
