I just want to clarify for readers: this statement is inaccurate.
"zpool replace" can (should) be used on anything (mirrors, raidzX,
etc.).
I have used "zpool replace" myself on FreeBSD on raidz1 without problems
for years. Here's valid proof, and this is not "simulated" or done on a
VM or anything like that -- this is bare metal.

Full commands/output are provided there as well (there's a link within
my blog post providing full output).
