Yes, that's the point. I understood you the first time, but whatever; if significant numbers of people don't, then finding a clearer way to say it is worth working on. > Even if there WAS a snapshot pool function. And there is, in most of our heads, such a function; since there's a filesystem at the pool level, and a "-r" switch :-). I think of "zfs snapshot -r rememberthispointint...@rpoool" as "taking a snapshot of rpool". I see that, if you're using volumes and such, that thinking starts to diverge more noticeably from reality. But I'm not, in my data pool, which is the one I care about. -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
