Hi,
I am currently in the process of moving all my data around, going from a
single zfs drive (ex-mirror) to a zfs raidz.
I have used cpio to copy the data to the new pool, but a du shows a big
difference in the results.
Does anyone have any ideas, or does a "du -h ." not do what I think it
should?
Cheers
Paul
