- If you make a zfs filesystem on a disklabel partition (eg wd0f) and the disk moves zfs does not seem to be able to find it again. If you run MAKEDEV for the affected device into a new directory and point zfs at that then it picks up the disk. This gave me something of a scare. zfs best practice is to use raw devices, so this shouldn't be an issue for most people
I hit with issue with my experiments with the Root On ZFS ramdisk.Coupled with the fact that the ramdisk needs the FFS boot partiton to be labelled makes GPT a must have.
