  • ONTAP 9
  • Foreign aggregate 

Issue

  • Nodes unjoined from a cluster, wiped, then joined back to the cluster.
  • It also can be caused by an improper head swap procedure. 
  • Their foreign aggregates are in a stale state (no import nor destroy possibility)
  • Cannot remove foreign aggregates to free disks and operate the shelves (Change IDs, re-create new aggregates etc.):
::*> aggr remove-stale-record -aggregate aggr_2 -nodename cluster01-04
Error: command failed: Failed to delete aggregate "aggr_2". Reason: Aggregate 'aggr_2' cannot be destroyed because it is online. You will need to take it offline before destroying it.
 
::*> aggr offline -aggregate aggr_2 -force-offline
Error: command failed: Failed to check if aggr_2 is a foreign(unknown) aggregate. Reason: entry doesn't exist.
  • Disks are still assigned:
::> disk show -nodelist cluster01-04 -fields owner,aggregate
disk owner aggregate
