For most types of deployments, including search head clustering, Splunk recommends that you use normal bundle replication, rather than mounted bundles with shared storage.

As a result of changes to bundle replication made in the 5.0 timeframe, such as the introduction of delta-based replication and improvements in streaming, the practical use case for mounted bundles is now extremely limited. In most cases, mounted bundles make little difference in the amount of network traffic or the speed at which bundle changes get distributed to the search peers. At the same time, they add significant management complexity, particularly when combined with shared storage. Because of delta-based replication, even if your configurations contain large files, normal bundle replication entails little ongoing replication cost, as long as those files rarely change.

If required, especially In a ginormous environment, mounted bundles work really well under a well-constructed rsync strategy (vs. using shared storage).
