Brooke: If you’re using ZFS for a boot disk, you have to use slices anyway at the moment (see my HOWTO: Migrate a UFS Root Filesystem to ZFS post), so yes, you’ll need to use slices for the LU. This isn’t the case in OpenSolaris though as it uses a different upgrade mechanism taking better advantage of ZFS snapshots.

How about creating and ALT BE for LiveUpgrade while using ZFS?
Does it require two different zpools, and if so, if you only have two disks this would force you into handing disk slices off to ZFS (something ZFS prefers you don’t do for performance reasons).

Chris: You can share it by running either:

# zfs set sharenfs=on /sata/satapool

… and then access the filesystem from your XP machine over NFS

# zfs set sharesmb=on /sata/satapool

… and then access the filesystem from your XP machine over CIFS/SMB (you shouldn’t need USFW for this). This last one does require you to be running a certain level of OpenSolaris/SolarisExpress, but I can’t remember which rev off the top of my head. Check which rev of nevada introduces native CIFS support.

How do you properly share a ZFS pool? I’ve got a pool that I created using

zpool create sata /dev/dsk/c6d0 /dev/dsk/c7d0
zfs create /sata/satapool

I’m trying to use a ZFS pool on an OpenSolaris server from a Windows XP PC with UNIX services installed.

Great tip Alex. Thanks.

Thanks for this very good Cheatsheet.

Regarding destroying a snapshot having a dependent clone, you get the following error:

# zfs destroy local/alex@1
cannot destroy ‘local/alex@1′: snapshot has dependent clones
use ‘-R’ to destroy the following datasets:
local/clone1

I was wondering a way to be aware of all the zfs that actually are clones of a snapshot (not having to try and fail on a destroy):

I found the following way:

# zfs get origin
NAME PROPERTY VALUE SOURCE
local origin - -
local/alex origin - -
local/alex@1 origin - -
local/alex/subdir01 origin - -
local/alex/subdir02 origin - -
local/clone1 origin local/alex@1 -

–> that way you can see which zfs is clone of a snaphot.
