ZFS Configuration question

Question

Hello,
I have 2 x 140GB (hw Raid-0 + spare). About 20GB is allocated to Solaris on UFS (standard installation and partitions/slices).
I would like to allocate the 120GB space left to ZFS. I found a lot of documentation of how to create a ZFS Pool on an empty disk drive. The documentation is less clear on how to do it on a drive already use by another FS.
One of the document found talk about using format / fdisk and define that partition as DOS or anything else). I tried different things around that, but a piece of the puzzle is missing.
Any help will be appreciated.

Answer 1

I have no room for the ZFS partition on a slice. I
have a lot of free space unallocated to any partition
and this is where I would like the ZFS partition.You would need to allocate it to one yourself.
I
saw a lot of confusion between slices and
partitions.Yes. In many cases they are used interchangably.
However, I often try to use the term "slice" for the solaris label subdivision, leaving "partition" to refer to x86 architecture-specific divisions.
Solaris on x86 can only (easily) use a single x86 partition of type "Solaris". You can't use another partition (whether with ZFS or not).
In my case, I have a 20GB partition where I have 10
slices created when I installed Solaris on UFS.
The 120GB left is not allocated to any slice.If it's visible to the Solaris label, then allocate it to a slice.
