I’m using FreeBSD 10.2-RC2. One of my new hard 3TB drives was acting up. I removed it and sent it off to be replaced. In the meantime, I received some 5TB drives and I added one of them into the existing vdev of the zpool. First, I partitioned the drive much like the other drives

I haven’t tested this yet, but I’ve installed the hardware. The real test will come after a reboot and actual use of the new drives. NOTE: Although this claims to be creating a new ZIL (SLOG) do not believe it. In fact, stop reading right here. There is nothing of use below. What will they
