Is that with grub or new loader?

Original zfs boot with grub (and note - illumos grub 0.97-based with zfs support, not just any other!) relied on rpool components' device path strings, which change if you plug to different usb port, switch bios from ide to sata, dual-boot vm/baremetal in a partition, maybe even add/remove usb storage devices while they are preferred for boot so enumeration for MoBo HBAs change, etc.

Usually a livecd, liveusb, firefly failsafe etc. can help you import and export the pool, this rewrites saved device paths.

New loader *I think* should be less picky about this aspect.

Hope that helps,
Jim
