Issue

  • Deletion of a volume  in SVM  via Terraform on ONTAP is failing due to stale references to a non-existent FlexCache volume
  •  REST API errors are returned during the delete operation, indicating that the volume is still considered the origin for a FlexCache relationship, even though no FlexCache caches are currently shown for the origin volume.
  • Attempts to clean up the FlexCache relationship using ONTAP commands have failed, and the issue persists despite no recent changes or maintenance in the environment
  • On the origin, we see '[kern_mgwd:info:4232] Warning: REST: Cluster peer cache miss for peer cluster <cache cluster peer uuid>'
  • Command to clean up the cache relationship failed,  flexcache origin cleanup-cache-relationship -origin-volume <origin_vol> -origin-vserver <origin_vserver> -cache-vserver <cache_vserver> -cache-volume <cache_volume> -force-retry true
