If you pause synchronous replication for a single volume in a synchronous replication collection, the synchronous replication
status of the paused volume is paused, and the other volumes in the collection are shown as being out of sync, even though data
is still written to their active and alternate pools. The system brings the collection back in sync after synchronous replication is
resumed for all volumes.
