zfs discuss - Mar 2009 - ZFS snapshot successfully but zfs list -r does not list the snapshot

Gurus;

I am using OpenSolaris 2008.11 snv_101b_rc2 X86

Prior to this I was using SXCE built 91 (or thereabout)

On build 91, after the command

#zfs snapshot -r myplace

I could easily see the snapshot using ZFS list.

But after install OpenSolaris 2008.11 snv 101b, I once again created a 
snapshot using zfs snapshot.

root at sunlight:/root# zfs snapshot -r myplace at First
root at sunlight:/root# echo $?
0

But subsequent attempts to use zfs list simply does not list the 
snapshot, only the original volumes and file systems.

root at sunlight:/root# zfs list -r myplace
NAME                USED  AVAIL  REFER  MOUNTPOINT
myplace            1.06T  1.61T  28.4K  /myplace
myplace/Docs       3.23G  1.61T  3.23G  /export/home/admin/Docs
myplace/fedora     26.9K  1.61T  26.9K  /export/home/admin/vbox/fedora
myplace/home       17.9G  1.61T  17.9G  /export/home
myplace/projects   5.41G  1.61T  5.41G  /export/home/admin/projects
myplace/solaris    9.30G  1.61T  9.30G  /export/home/admin/vbox/solaris
myplace/solzone    1.58G  18.4G  1.58G  /myplace/solzone
myplace/windoze    26.9K  1.61T  26.9K  /export/home/admin/vbox/windoze

I can easily remove the snapshot using "#zfs destroy -r myplace at
First"
and this proves the snapshot was successfully created (besides the fact 
that the zfs snapshot command returned a zero exit code).

root at sunlight:/root#
root at sunlight:/root# zfs destroy -r myplace at First
root at sunlight:/root# echo $?
0

Has there been a change in the interface?

Hi Steven,

Try doing ''zfs list -t all''.  This is a change that went in
late last year
to list only datasets unless snapshots were explicitly requested.

Yes as discussed on this list previously.

Snapshots are now not in the default zfs list output, but can be 
requested with -t all or -t snapshot.  Or you can change the pool level 
listsnapshots property to revert to the old behaviour.

Since snv build 99, zfs list no longer displays ZFS snapshots by default.
Instead, the zfs list command will display only filesystems and volumes.

On systems with large number of snapshots, the snapshot info can flood
the output, making the default zfs list command less useful in the
case where the user is not interested in information about snapshots.

A new pool level property called "listsnaps" permits control of the
zfs list output for that pool.  The value for the new property can be
set at pool creation time and import time, and can be changed later
with the "zpool set" command.

The -t option to the zfs list command takes precedence over the value
of the "listsnaps" property so "zfs list -t snapshot" or
"zfs list -t all"
will display all snapshots including those associated with pools where
the "listsnaps" property is off.
