I've tried so many things today I don't even remember them all but I will try to make the list as complete as I can. I recently purchased a new server with 3 450GB SAS drives on an mfi controller and 2 Xeon 5550 processors. I'm trying to install FreeBSD current with a ZFS RAIDZ pool booting from GPT. I have a USB drive booting ZFS based on the 200905 current snapshot. I downloaded the latest svn source and built it. LOADER_ZFS_SUPPORT=YES was set for the build. Once the build was complete I did the following to create and populate the pool on the 3 SAS drives while booted from the USB drive: gpart create -s GPT mfid[0-2] gpart show mfid0 # to get sector count gpart add -b 34 -s 128 -t freebsd-boot mfid[0-2] gpart add -b 162 -s 876,951,323 -t freebsd-zfs mfid[0-2] gpart bootcode -b /usr/obj/amd64/usr/src/sys/boot/i386/pmbr/pmbr -p /usr/obj/amd64/usr/src/sys/boot/i386/gptzfsboot/gptzfsboot -i 1 mfid[0-2] zpool create serenity raidz /dev/mfid[0-2]p2 make installworld TARGET=amd64 DESTDIR=/serenity make installkernel TARGET=amd64 DESTDIR=/serenity mergemaster -D /serenity/etc/ -i created an empty fstab copied /boot/zfs/zpool.cache to the new pool I did not export the pool as some searching showed that this will cause the boot to fail. I currently seem to be having 2 issues. One is that I get several screenfulls of "error 1 lba xxx" with numbers like 4292179434 and 4292179446. Similar errors were reported here http://lists.freebsd.org/pipermail/freebsd-fs/2008-December/005511.html but I did not find anything in that thread that worked for me. The error message itself comes from here http://svn.freebsd.org/viewvc/base/head/sys/boot/i386/gptboot/gptboot.c?revision=181436&view=markup The loader then proceeds to load the kernel, opensolaris, and zfs modules. Right before the displaying the loader menu it shows the message "ZFS: i/o error - all block copies unavailable" which comes from here http://svn.freebsd.org/viewvc/base/head/sys/boot/zfs/zfsimpl.c?revision=192194&view=markup If I continue from the loader screen the kernel loads and initializes and fails with "Trying to mount root from zfs:serenity ROOT MOUNT ERROR: If you have invalid"... "Loader variables: vfs.root.mountfrom=zfs:serenity zfs.root.mountfrom.options=" At this point I can't do anything because the USB keyboard does not respond and the system has no PS/2 ports. I'd love to get this working and any help is much appreciated. I still have the USB drive booting the 200905 snapshot and the livefs DVD snapshot available. Thanks, Jonathan P.S. if someone wants to do some testing on a 16 core machine with 6GB of RAM please let me know. I have a week or so to play with the machine.
