I have ZFS on my 7.1-PRERELEASE system, and while it does some spiffy things, in general I'm a bit underwhelmed. PROS: Adding new filesystems on a whim is really nice. It has a lot of really cool other features that I will probably never need. CONS: I have nearly 3GB of wired RAM, but it doesn't seem to be all that fast. For example, starting an Amanda backup on a UFS2 filesystem would get through the "estimate" phase almost instantly on a system that had been up for several days because of cached filesystem data. On ZFS, it still limps along even if I just finished the last backup a few minutes earlier. Other than saying "I'm using ZFS", I don't seem to have much to show for it. WTF: "Raidz and top-level vdevs cannot be removed from a pool." At this point, I'm almost ready to go back to good ol' UFS2, but I'd hate to give up that easy addition of new filesystems. I *could* have a single 700GB root FS but that just doesn't seem right. Are there any good, tested GEOM- based ways of getting that functionality, perhaps along the lines of using something like gvirstor and growfs as needed? - Kirk
