I just couldn’t wait any longer, and decided to try something with ZFS. And what do you know? I’ve found a very useful advice from Ben Rockwood, which allows us use regular files created with mkfile as virtual disks for ZFS. VERY useful, especially when you really want to play with such a great technology and maybe try various configurations, but there are no spare physical disks for such experiments.
I will, of course, read and understand all the inner workings of ZFS later, but the first impression of it is this – too easy to be true! 🙂
