问题描述

  • 在 "storage failover giveback" 完成后,"ofnode" 在 vreport 中为 "Blade UUID" 报告 "aggregate Differences"
  • vreport difference 是 WAFL 报告 "fromnode" dblade UUID 和 VLDB 错误地报告在回馈操作期间重新定位的 SFO 聚合的 "ofnode" dblade UUID示例:
    ::*> debug vreport show
    aggregate Differences:
    Name Reason Attributes
    -------- ------- ---------------------------------------------------
    aggr1 Present both in VLDB and WAFL with differences
    Node Name: node-01
    Aggregate UUID: c88f874f-9237-4ad9-a0f0-ecd0cb492d96
    Aggregate State: online
    Aggregate Raid Status: raid_dp, mirrored
    Aggregate HA Policy: sfo
    Is Aggregate Root: false
    Aggregate Vol Count: 130
    Is Composite Aggregate: false
    Differing Attribute: Blade UUID
    WAFL Value: a32cf117-8251-11eb-a586-d039ea450084
    VLDB Value: d483d5e0-8250-11eb-a5eb-d039ea45008b

  • 对于该聚合上托管的受害卷,vreport 还可能报告 "junction Differences"示例:
    Name Reason Attributes
    -------- ------- ---------------------------------------------------
    mySVM:myVol File Handle for the Parent Volume does not match with Dblade
    Parent Info:
    VolName: myVol
    MSID: 2147484730 DSID: 6583 vsID: 19
    Child:
    VolName: myVol
    MSID: 0 DSID: 6565 vsID: 19

  • 对于在 "fromnode" 上托管的 LIF 的客户端数据访问在回馈后失败,除非它们被迁移到 "ofnode"
  • 如果在 "ofnode" 被接管时进行了配置更改,这些更改可能在回馈后对 "ofnode" 的管理平面仍然未知,导致在 "ofnode" 上的操作在回馈后出现意外行为
