Implementation of SyncRep

We decided to change our configuration a bit. Previously, we had 2 identical virtual hosting platforms in 2 rooms of different servers on campus. Both consisted of 3 Dell servers in a cluster failover and a PS4100 with a CSV file that is stored on each San. Our main platform replicated VM to the test backup via the replication of Hyper-V. Because our needs have increased, resources on 3 host servers can no longer hold a charge and have enough to spare for failover. We have moved the 3 backup hosts to the main server room and we'll be adding them in the existing cluster, then replicating the San, if all goes well using SyncRep. I added SAN backup in the group with the main SAN and created a separate storage pool, but when I try to activate SyncRep, we discovered our problem.

The volume that we have implemented for the CSV file is 6.5 TB we have only enough space for a reserve of instant 6% I thought that this would be allowed, as the minimum requirement of SyncRep is 5%, but during the initial synchronization begins, he fills the snapshot reserve and then up an error indicating that the snapshot reserve is exhausted and starts the process again. I don't know where to go from there, is it possible to do a manual synchronization, similar to traditional replication with manual transfer utility?

Here is a screenshot of what I see:

Thanks in advance for any advice you may have for us.

Hello

There is no rep manual synchronization.   Let me start with a volume provisioning for more space for the reserve of the snapshot.  I would also try to do for other volumes of extra free space as well.

You have the initial 4 + TB to sync, more new writing to come in the snapshot reserve if additional is necessary.

What is the interconnection between the source and the other pool?   They are on the same switches?

If this still fails I would say an opening support cases.

Kind regards
