Linux is the first operating system that can boot from RAID-1+0, RAID-Z or RAID-Z2 ZFS, really cool trick to put zfs-fuse in the initramfs. ( Solaris can only boot from single-disk or RAID-1 pools ) http://www.linuxworld.com/news/2007/061807-zfs-on-linux.html http://groups.google.com/group/zfs-fuse/browse_thread/thread/3e781ace9de600bc/230ca0608235e216?lnk=gst&q=boot&rnum=1#230ca0608235e216 This message posted from opensolaris.org

( Solaris can only boot from single-disk or RAID-1 pools )Note that this method is much like the old ''UFS mountroot'' support which was replaced in favor of the current native GRUB boot. This method could support arbitrary pools at the cost of maintaining an extra UFS slice. You basically boot from something that GRUB can read (in this case initramfs), and then "switch" to the real boot environment. This is very different from booting natively from GRUB, as you have to maintain two separate boot environments (one on your initramfs and one in your ZFS root). - Eric -- Eric Schrock, Solaris Kernel Development http://blogs.sun.com/eschrock

Looks like the FUSE port to linux is getting an entirely different audience excited about ZFS... nice. eric

Anyway, nice to see progress with Linux port. -- Pawel Jakub Dawidek http://www.wheel.pl pjd at FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
