Hi,

With the recent changes allowing RaidZ boot, I thought I would finally drop my mirror pack and go RaidZ.

The only problem I now have is
demophon# zpool set bootfs=DemoPool/root DemoPool
cannot set property for 'DemoPool': operation not supported on this type of pool

Is this still a work in progress, or do I have something a-miss?

I am using current as of today
"demophon# uname -a
FreeBSD demophon 8.0-CURRENT FreeBSD 8.0-CURRENT #17: Wed May 27 13:18:06 BST 2009 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/DEMOPHON amd64"

This is a limitation which I will remove as soon as I have a little time to work on it. Basically, Solaris can only boot from simple structures such as mirrors and collections of mirrors. The code enforces this by stopping you from setting the bootfs property if the pool configuration is too complex for the Solaris boot code. I will simply remove this limitation for FreeBSD since we can now boot from any pool configuration.

In the meantime, you can still boot if you put your root filesystem files in the root of the pool. Not ideal I know but I'll try to fix it properly soon.
