With the exception of Cindy's suggestion of using 4 disks and
mirroring (zpool attach two new disks to existing vdevs), I would
absolutely NOT do anything unless I had a known good backup of the
data! I have seen too many cases described here
just note that you can has different zpool name but with the same old
mount point for export purpose

IMHO, there is no easy way out for you
1)tape backup and restore
2)find a larger USB SATA disk, copy the data over then restore later
after raidz1 setup

Hi Bob,
Not many options because you can't attach disks to convert a
non-redundant pool to a RAIDZ pool.
To me, the best solution is to get one more disk (for a total of 4
disks) to create a mirrored pool. Mirrored pools provide more
flexibility. See 1 below.
See the options below.
Thanks,

Can somebody guide me? What's the easiest way out of this mess, so that I
can move from what is now a simple two-disk zpool (less than 50% full) to a
three-disk raidz configuration, starting with one unused disk?

Perfect, thanks. Just what I was looking for.
How do I know how large to make the fakedisk file? Any old enormous size
will do, since mkfile -n doesn't actually allocate the blocks until needed?
To be sure I understand correctly: In theory, instead of this missing disk
approach I could create
Wait, I'm not following the last few steps you suggest. Comments inline:

In theory, instead of this missing
disk approach I could create a two-disk raidz pool and later add the
third disk to it, right?
No, you can't add a 3rd disk to an existing RAIDZ vdev of two disks.
You would want to add another 2 disk RAIDZ vdev.
See Example 4-2 in this section:
read the link please
it seems that afmter you create the radiz1 zpool
you need to destroy the fakedisk so it will have contains data when you to the
copy
copy the data by following the steps in the link
replace the fakedisk withnthe real disk
this is a good approach that i did not know before

just give the old pool name to the raidz pool when I create it?
Cause you can't have two pools with the same name. You either need to
rename the old pool first, or rename the new pool afterwards.
But in your instructions you have me
