I'm trying out the new RAID-Z boot support, but I'm not having much luck. After finally getting VMware to get the boot order right (and not move on to PXE boot etc.) all I get is errors. See the original thread: http://www.nabble.com/Booting-from-ZFS-raidz-td21058594.html I followed in the footsteps on the first poster (maybe not such a great idea since it failed for him), even to the point of using three disks in VMware Fusion, although that was a coincidence. Anyway, I have a healthy "rpool" made out of three GPT partitioned disks, as in the post. The only thing I changed was $1 to the disk names (da2, da3, da4) and the size parameter for the freebsd-zfs partition. I then populated the pool with everything from my current r192914 install, and made sure that zpool.cache was up to date in /rpool/boot/ zfs (by copying the current copy there, and making sure it contained "rpool"). All I get is "error 4 lba xxxxxxxxxxx", 30+ times, followed by the loader starting to load the kernel, and failing with 10-15 lines of "ZFS: i/o error - all block copies unavailable". It can't load the kernel, manually or not. It does read loader.conf successfully though (since vfs.root.mountfrom and vm.kmem_max etc. are set correctly). System: FreeBSD 8.0-CURRENT (DTRACE) #4 r192914: Thu May 28 08:56:46 CEST 2009 Built with LOADER_ZFS_SUPPORT=YES in /etc/make.conf, no patches applied (since the raidz boot patch was merged to current a few days ago). Any advice? Regards, Thomas
