Project Replication Storage Pools

When the action is initially configured, the administrator is given a choice of which storage pool on the target should contain the replicated data. The storage pool containing an action cannot be changed once the action has been created. Creating the action creates the empty package on the target in the specified storage pool, and after this operation the source has no knowledge of the storage configuration on the target. It does not keep track of which pool the action is being replicated to, nor is it updated with storage configuration changes on the target.

When the target is a clustered system, the chosen storage pool must be one owned by same head which owns the IP address used by the source for replication because only those pools are always guaranteed to be accessible when the source contacts the target using that IP address. This is exactly analogous to the configuration of NAS clients (NFS and SMB), where the IP address and path requested in a mount operation must obey the same constraint. When performing operations that change the ownership of storage pools and IP addresses in a cluster, administrators must consider the impact to sources replicating to the cluster. There is currently no way to move packages between storage pools.
