It makes a lot of the common sysadmin tasks a whole lot easier. For instance, creating raid sets - by default it works with whole disks, which is exactly what you want 99% of the time (but you can specify a partition if you really want to). Want to check whether there is a data corruption error? "zpool scrub poolname" and it will go through all the disks on that pool, using the built-in ECC to verify that the data on the disks is OK. If not, it will try to fix it. "zpool status -v" lists all the disks, which mirrors or RAID sets each is part of, and when the last scrub was performed, along with errors or ECC problems. The one suggestion I would make for the btrfs guys is to really work on making the CLI commands simple and intuitive.
