NetApp Training Brain Dump: Data Replication

There are apparently different levels of synchronization, which we can observe from this sentence: "A (level-0 resync in progress) message indicates that a plex cannot be rejoined."*1  

"If the mirrored aggregate was in an initial resynchronization state (level-0) before the forced takeover, you cannot rejoin the two aggregates. You must re-create the synchronous mirror to reestablish the MetroCluster configuration."

Level-0 means that there was never an actively sync dataset: although the relationship is set up, the initial full transfer never completed.
