Just spitballing, but perhaps you could do something with ZFS send/receive. You could take frequent incremental snapshots and send them to the remote node. If you did this, say, every ~30-60 seconds during periods of high churn then perhaps all of the requisite blocks would still be in the ARC and you could send them without reading back from disk. We used to do this every 15 minutes on a pair of thumpers at the Uni I worked at. Has anybody done this with a shorter period? You may get more traction with the question on a ZFS mailing list. -- Joshua M.
