Symptoms

The Oracle ZFS Storage Appliance had three LUNs presented to a client host  that were then used on that host as part of another ZFS pool. 

All these LUNs had share level replication actions set on them and it was the replication copies of these LUNs that were used to make a ZFS pool on the client .

An issue occured such that the one of the replication actions got out of sync (or failed) . The result - on the client - was a ZFS pool that was incomplete because one LUN was out of sync with the rest.

 

To recover, the client host had to rebuild the ZFS pool from newly replicated copies.
