I don't mean to be offensive Russel, but if you do ever return to ZFS, please promise me that you will never, ever, EVER run it virtualized on top of NTFS (a.k.a. worst file system ever) in a production environment. Microsoft Windows is a horribly unreliable operating system in situations

I'll start: - The commands are easy to remember -- all two of them. Which is easier, SVM or ZFS, to mirror your disks? I've been using SVM for years and still have to break out the manual to use metadb, metainit, metastat, metattach, metadetach, etc. I hardly ever have to break out the ZFS

You can also import pools by their unique ID instead of by name. If the pool is not imported, 'zpool import' with no arguments should list the pool IDs. If the pool is imported, 'zpool get guid poolname' will list the pool ID. Beware that if the zpools have the same mountpoints set within any
