Christian Schwarz 975fdee217 replication & pruning: ditch replicated-property, use bookmark as cursor instead ... A bookmark with a well-known name is used to track which version was last successfully received by the receiver. The createtxg that can be retrieved from the bookmark using `zfs get` is used to set the Replicated attribute of each snap on the sender: If the snap's CreateTXG > the cursor's, it is not yet replicated, otherwise it has been. There is an optional config option to change the behvior to `CreateTXG >= the cursor's`, and the implementation defaults to that. The reason: While things work just fine with `CreateTXG > the cursor's`, ZFS does not provide size estimates in a `zfs send` dry run (see acd2418). However, to enable the use case of keeping the snapshot only around for the replication, the config flag exists.		2018-09-05 19:51:06 -07:00
