Applies to

  • ONTAP 9
  • SVMDR
  • MetroCluster

Answer

  • No; offlining or deleting MDV_CRS volumes can result in all SVM-DR or MetroCluster relationships failing to and from the cluster in question. Offlining or deleting MDV_CRS volumes can result in failures to configure and utilize the local cluster. This includes failures in modifying volume properties and even client-side protocol failures and outages.
  • MDV_CRS volumes are used for the Configuration Replication Service which is used in MetroCluster and SVM-DR (vserver disaster recovery) configurations.
  • MDV_CRS volumes are created and managed by ONTAP and cannot be created manually. It may be impossible to online an MDV_CRS volume which has been made offline or to re-create a deleted MDV_CRS volume.

 

  • If you have MDV_CRS volumes blocking operations, causing other issues, or if you have inadvertently deleted an MDV_CRS volume, 

    Please contact NetApp Technical Support or log into the NetApp Support Site to create a case. Reference this article for assistance with the solution. 

    • The solution requires Diagnostic-level recovery. 
    • The use of Diagnostic commands and recovery steps is potentially disruptive and should only be used with guidance from NetApp Support.
