No. "USED" is the space that would be freed if you destroyed the
snapshot _right now_. This can change (and usually does) if you
destroy previous snapshots.

The amount of data that is reachable from the file system root. It's
just what I would call the contents of the file system.

Hi all,
Two questions from a newbie.
1/ What REFER mean in zfs list ?
2/ How can I known the size of all snapshot size for a partition ?
(OK I can add zfs list -t snapshot)

I create snapshots on my datasets quite frequently. My understanding of the
USED property of a snapshot is that it indicates the amount of data that was
written to the dataset after the snapshot was taken. But now I'm seeing a
snapshot with USED == 0 where there was definitely write activity aft
OK, to answer my own question (with a little help from Eric!) ...
I was using vi to edit the file which must be rewriting the entire file back
out to disk - hence the larger than expected growth of the snapshot.

How are you editing the file? Are you sure your editor isn't writing
out the entire file even though only four characters have changed? If
you truss the app, do you see a single 4 byte write to the file?

Hi,
We're currently testing a Thumper running Solaris10 with a view to buying a
couple.
I'm not seeing what I would expect to see as far as snapshot space utilization
and am hoping someone could explain why.
Here's what I'm doing -
Creating an empty zpool & zfs
Creating a 6MB text file
