I have two centera Gen4 boxes : Primary and remote with  bidirectional replication.

Recently we had centrastar upgraded to-4.1.0,but soon started having replications stopped because the source  cluster was apparently not having enough space.

The source Centera is running out of capacity. Only 279 GB of space is available.and EMC is insisting on adding more capacity to resolve the parking issue.

I also a the garbage collector to reclaim a sweep space of 121 GB.

I need to convince the customer to opt for adding more nodes to the source cluster . What should be my convincing statement ?

At this point : Replication is paused and there is parking overflow.

What 're the implications of not heeding to the above issue  and letting the replication be in puased state with paking .

Thanks in advance!
