thanks for sharing your dedup experience. Especially for Virtualization, having

So you see a dedup ratio of 1.29 for two installations of Windows Server 2008 on

The create-time permissions do not provide the correct permissions for

Yes, it is helpful in that it reviews all the steps needed to get the
replacement disk labeled properly for a root pool and is identical
to what we provide in the ZFS docs.
The part that is not quite accurate is the reasons for having to relabel
the replacement disk with the format utility.

This really depends on if you are willing to pay in advance, or pay
