ZFS uses COW (copy on write) during writes. This means that it first has to find a new location for the data and when this data is written, the original block is released. When using snapshots, the original block is not released. I don't think the use of snapshots will alter the way data is fragmented or localized on disk. --- PeterVG -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
