Suppose I've used a pair of drives laid out with GPT partitions to create a mirror. Actually, this situation requires that individual partitions be mirrored instead of the whole drive. Then suppose one of these partitions is to be gjournaled, but with separate data and journal providers. The separate journal provider will be in another partition. I believe I should gmirror the journal provider partition just as I did the data provider partition. Correct me if this is wrong. Then, should I be enabling or disabling auto-synchronization for the mirrored journal provider partition? It is clear to me that it should be disabled for the mirrored data provider partition because the journaling will ensure data consistency, but is the content of the journal provider itself guaranteed consistent under all circumstances?
