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

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.

Hi Lutz,
You can try the following commands to see what happened:
1. Someone else replaced the disk with a spare, which would be
recorded in this command:
# zpool history -l zfs01vol
2. If the disk had some transient outage then maybe the spare kicked
in. Use the following command to see if so
I went through with it and it worked fine. So, I could successfully move my ZFS
device to the beginning of the new disk.
