I'm not sure how you're intending to switch between each of these three different OSes while you're building your RAIDZ based system -- normally you'ld use something like grub, but given this is only intended to be a temporary state, you probably don't want the bother of setting that up. If you want to copy files between the existing 10.3 setup and the new 11.0 RAIDZ then it will be pretty trivial to boot into one of those OSes and mount the filesystems from the other -- but there are pitfalls to booting into 10.3 and trying to mount the 11.0 files: - When you import the 11.0 ZFS remember to use the '-R /mnt' flags, or it will overlay your exising root directory - As I recall, there are some new feature flags in ZFS under 11.0 that aren't supported in 10.x, which you need to avoid using to maintain compatibility. See zpool-features(7) for the full details. Best to render the whole question moot and boot into 11.0 and then mount any 10.3 filesystems onto that. > I will have win7 on the first primary drive an SSD and then > remove the second drive after I get this going. >=20 > I want to create filesystems on the Raid Z array like /usr/home= > /usr/ports /usr/ports/packages etc. >=20 > You can suggest any other filesystems if it will be helpful= =2E One thing you might want to consider is using some space on your SSDs for a separate ZIL and/or ARC device -- this can give you a significant performance boost, although how much does depend greatly on your workload and mix of files. The other thing when creating ZFSes is to resist the temptation to make huge numbers of them. Just because you can, doesn't mean that you should. Given the shared storage nature of ZFS, you really only need a separate ZFS as a hook to apply different flags to a specific tree of files. On the whole, it is easier to manage one big ZFS than many small ones.
