Hi,

We have a server running b134. The server runs xen and uses a vdev as the storage.

The xen image is running nevada 134.

I took a snapshot last night to move the xen image to another server.

NAME                         USED  AVAIL  REFER  MOUNTPOINT
vpool/host/snv_130             32.8G  11.3G  37.7G  -
vpool/host/snv_...@2010-03-31  3.27G      -  13.8G  -
vpool/host/snv_...@2010-08-03   436M      -  37.7G  -

It's also worth noting that vpool/host/snv_130 is a clone at least two other snapshots.

I then did a zfs send of vpool/host/snv_...@2010-08-03 and got a 39GB file.
A zfs send of vpool/host/snv_...@2010-03-31 gave a file of 15GB.

I don't understand why the file is 39GB since df -h inside of the xen image drive vpool/host/snv_130 shows:
Filesystem             size   used  avail capacity  Mounted on
rpool/ROOT/snv_130      39G    12G    22G    35%    /

It would be nice if the zfs send file would be roughly the same size as the space used inside of xen machine.
