Yes, the man page says that. However, it is possible to mix disks of different sizes in a RAIDZ, and this works. Why does it work? Because RAIDZ stripes are dynamic in size. From that I infer that disks can be any size because the stripes can be any size. Should one or more of the smaller disks become full, the stripe information is written across the remaining space on the rest of the bigger disks. Or should be anyway. If you think about it, it makes sense. Be that as it may, I remember I read that somewhere on a blog, and I do believe it had been Mr. Bonwick's blog, although I could be wrong.
