Of course. > Is there a way to reserve space in zfs pool to be used by snapshot or clone? Snapshots are read only, so no need for a reservation. Clones can be given reservations. NB, there are two kinds of reservations: reservations work on the dataset size refreservations work on the dataset and snapshots sizes the two differ in the accounting of snapshots. For more information, see the "Setting ZFS Quotas and Reservations" in the ZFS Administration Guide. -- richard ZFS storage and performance consulting at http://www.RichardElling.com ZFS training on deduplication, NexentaStor, and NAS performance http://nexenta-atlanta.eventbrite.com (March 16-18, 2010) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
