适用场景

  • 适用于 VMware vSphere ( SCV ) 4.5 的 SnapCenter 插件
  • 多个存储虚拟机( SVM )之间存在重复的 NFS IP 地址

问题描述

  • 选择控制阀有时会选择错误的 SVM 作为备份目标,然后会发生故障
  • vmcontrol_<JOB_ID>.log 显示 SCV 使用重复的 NFS IP 选择了错误的 SVM

DEBUG <HOST> --- [tp1694819250-10] c.n.a.d.VsphereDiscoveryManager      : Datastore type is NFS
DEBUG <HOST> --- [tp1694819250-10] c.n.a.m.DatastoreStorageDetailsCache    : Calling GetNasStorageInfo with NFS LIF <IP> and exportPath <EXPORTPATH>
..
DEBUG <HOST> --- [tp1694819250-10] c.n.a.m.DatastoreStorageDetailsCache    : Calling GetNasStorageInfo with NFS LIF finished
DEBUG <HOST> --- [tp1694819250-10] c.n.a.m.DatastoreStorageDetailsCache    : Storage footprint found for nfsLif <IP> and exportPath <EXPORTPATH>:  ipAddress null vserverName <SVM> volumeName <VOLUME> junctionPath <JUNCTIONPATH> isLocatedOnFGfalse

  • Job-<JOB_ID>.log 显示对 错误 的 SVM 执行请求 后失败

示例:

[DBG] Running Command New-NcSnapshotMulti controller name : <IP>, vserver : <SVM>
[ERR] API exception
[ERR] Failed to run a command New-NcSnapshotMulti
[DBG] ex.Message : Invalid input. Reason: Operation allowed only on Read_Write (RW) volumes. 
[DBG] ex.InnerException.Message : Invalid input. Reason: Operation allowed only on Read_Write (RW) volumes. 
..
[ERR] Error: Snapshot operation failed, Exception:Failed to run a command New-NcSnapshotMulti

  Invalid input. Reason: Operation allowed only on Read_Write (RW) volumes.

注意: 错误可能因配置而异
