ZFS is awesome. I never would have imagined I could ever get excited about a filesystem, but I did. If you've never used it, I encourage everyone to check it out. It's so completely "flexible" and you can do things that you never would've thought of.
A while back, my personal mail server ran on FreeBSD 9.x on bare metal. I wanted to rebuild the physical host but run everything in jails on a "clean" 10.x install instead. I created a new virtual machine on our ESXi cluster, booted it with an mfsbsd image, and prep'd the hard disks. Back on the server, I shut down all the services, took snapshots, and shipped them off to the VM using ZFS send/receive. In short order, I had P2V'd my mail server and it worked wonderfully. I left everything running in that VM for a few days while I rebuilt the physical server and got all of my jails set up and then moved it all back.
Allan Jude gave a cool talk at vBSDcon a few months ago entitled "Interesting Things You Didn't Know You Could Do With ZFS" [0]. If you've never used ZFS or you're wondering what it might have over your current filesystem of choice, you might check it out.
