jumpstart profile example:

In addition to the standard containing the carnage arguments used to
justify splitting /var/tmp, /var/mail, /var/adm (process accounting

I currently have a zpool with two 8Gbyte disks in it. I need to replace them
with a single 56Gbyte disk.
with veritas I would just add the disk in as a mirror and break off the other
plex then destroy it.
I see no way of being able to do this with zfs.
Being able to migrate data without
independently either I need to have a zpool per zone or I need
to have per-dataset replication. Considering that with some workloads
20+ zones on a T2000 is quite feasible, a T5240 could be pushing 80+
zones and as such a relatively large number of zpools.

Could someone kindly provide some details on using a zvol in sparse-mode?
Wouldn't the COW nature of zfs (assuming COW still applies on ZVOLS) quickly
erode the sparse nature of the zvol?
Would sparse data-presentation only work by delegating a part of a zpool to a
zone, but that's at the
name, temp.
