These two last_replicated snapshots are different and denoted" master" and "slave"
accordingly.
The outcome for the synchronous mirroring:
v The Master blocks host I/O for the duration of creating the snapshots
v The Master completes synchronizing pending writes
v A snapshot of the Master and Slave is taken
v The Master no longer blocks host I/O
v An event is generated
