ONTAP SAN SnapMirror Active Sync out of sync after disaster
Applies to
- ONTAP
- SnapMirror Active-sync
Issue
- After ISP failure caused both clusters and mediator to lose all network connectivity, SnapMirror Active-sync (SM-as) relationship does not resync
- Attempted to recreate the existing snapmirror relationship but synchronization fails
- Cluster health, peering and mediator have returned to normal but synchronization fails
- New fresh SM-as relationships with new volume and snapshots can be created with no issue
Example:
snapmirror show -destination-path<svm:volume>
Last Transfer Error: Failed to remove replication resources from source. (SnapMirror Synchronous Endpoint operation is not supported as it is involved in a pending operation.)
Last Transfer Error: Failed to add owner transfer to Snapshot copy on volume Failed to add owner transfer to Snapshot copy on volume x Snapshot copy does not exist
netinterface show -role intercluster
clusterpeer show
clusterpeer health show -destination-cluster <peer_cluster>
