Yes, you can create multiple clones of a single snapshot, without penalty. > Clone has a distinct, generic meaning that does not imply a fixed or > lasting relationship to the parent, but rather an inheritance.

This relationship must be maintained for internal accounting purposes, but also for the administrator to know which clones are sharing space with the original snapshot. We tried for a while to allow a means to destroy the original filesystem (thereby 'divorcing' the clone from its snapshot), but it's just not doable, both from an implementation perspective and a space accounting perspective. - Eric -- Eric Schrock, Solaris Kernel Development http://blogs.sun.com/eschrock _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
