Think of Nevada as a distro name (in Linux terms), which uses the OpenSolaris source base. There are (generally) weekly builds, which is what you will see referred to as B61. Solaris Express is the marketing name for periodic releases of specific builds of Nevada (so, every couple of months, a build of Nevada is released as Solaris Express - it's for people who want the latest technology,, with _some_ support options, while not living on the absolute bleeding edge like us folks). The thing is: I am creating a network centered storage server, and for that I'd like to have a somewhat stable OS. I would like to use ZFS and then snapshot to another node (quite freqently) which should give me some DRBD like behavior. IMHO I wanted to have just one giant raidz zfs pool that can be booted from and not bother with the rest. I thought it would be rather hard to support RAIDz as a root pool. Though I gave it a try. Maybe I just should forget the root zfs stuff, if i nonetheless have to use 2 pools in order to have the rest use raidz which is what i need for robustness. Maybe I will just take a hardware raid approach to the root partition (just to have failover support) and to not make the one giant root approach using zfs. One ZFS related question: If I use the ufs partition to boot into the ZFS partition (the old rootfs stuff), raidz should then be technically speeking possible? Since in this case grub is using UFS to load the platform kernel and the initial ramdisk? So maybe it should work to have a very small UFS partition mirrored manually on several disks and then to boot into a raidz ZFS. My ZFS partition FAULTED when I tried to boot via UFS on Solaris 10. Is the root fs support mentioned in: http://blogs.sun.com/tabriz/#are_you_ready_to_rumble supported in Solaris 10? Thanks. I am sorry for so much noise on this file system related list. -- Jakob ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

The design is still being worked out, but it's likely that it will involve a new kind of dataset which is replicated on each disk of the RAID-Z pool, and which contains the boot archive and other crucial files that the booter needs to read. I don't have a projected date for when it will be available. It's a lower priority project than getting the install support for zfs boot done.

Also to Malachi, who informed me of this also. I expect that the same replicate on all disks dataset property that I'm proposing for booting from RAIDZ would enable us to implement booting from raid-10 too.

This sounds a lot like: 6417779 ZFS: I/O failure (write on ...) -- need to reallocate writes Which would allow us to retry write failures on alternate vdevs. Of course, if there's only one vdev, the write should be retried to a different block on the original vdev ... right?
