If the filesystem you are doing the incremental 'zfs recv' into is always unmounted, you should not see the "fs modified since last snapshot" error. Can you send the specific commands / output that you're seeing? Is a crash / power loss involved? Also note, 'zfs set mountpoint=none' is the preferred method to not mount a filesystem + its descendents. --matt ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Ok, so -F option is not in U3, is there any way to replicate file system and not be able to mount it automatically? so when I do zfs send/receive it wont be mounted and changes would not be made so that further replications could be possible? What I did notice was that if I am doing zfs send/receive right one after another I am able to replicate all my snaps, but when I wait a day or even few hours I get notice that file system got changed, and that is because it was mounted and I guess because of that I am not able to perform any more snaps to be send... any idea what I could do meanwhile I am waiting for -F?

Chris, This option will be available in the upcoming Solaris 10 release, a few months from now. We'll send out a listing of the new ZFS features around that time.
