If you use ZFS to wrestle a JBOD array into its version of RAID1+0, when comes time for resilvering (i.e., rebuilding a failed drive), ZFS smartly only copies the used blocks and skips over unused blocks. > It sounds like ZFS isn't included in the mainline kernel.

There has been a discussion on that in this list, and there is some concern that ZFS' license (CDDL) is not compatible with the Linux kernel license (GPL), so never the twain shall be integrated. That said, if your kernel supports modules, it's a piece of cake to compile the ZFS modules on your own. @ryao has a zfs-overlay you can use to emerge ZFS as a module. If you have configured your kernel to not support modules, it's a bit more work, but ZFS can still be integrated statically into the kernel. But the onus is on us ZFS users to do the necessary steps.
