gptzfsboot dell r510 fails

[Philip M. Gollucci]

Hi All,

Dell r510
24GB RAM
8 disks in the following order
0-1 - 25gb ssd sas
2-7 - 136gb sas

http://svn.freebsd.org/base/releng/8.0@203057

which does not include
http://svn.freebsd.org/viewvc/base?view=revision&revision=199714

so following
http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ2
[/etc/src.conf: ZFS_LOADER_SUPPORT=true]

which I've gotten to work on 500+ dell machines on the above fbsd 
version. [860,1435sc,1950,2950,2970,r710]

So I've setup the zpools via the livefs as

zroot (mirror)
   /dev/gpt/disk0 -> mfid2[p3]
   /dev/gpt/disk1 -> mfid3[p3]

zmysql (raidz1)
   /dev/mfid[4567]
   cache
     /dev/mfid[01]

I've selected the 3rd device in the perc h700 bios [mfid2]
to be the 'bios boot device' which amazingly to me actually worked.

During the boot I get to the standard

ROOT MOUNT ERROR:
....
set vfs.root.mountfrom.options=rw

Loader variables:
   vfs.root.mountfrom=zfs:zroot
   vfs.root.mountfrom.options

Manual root filesystem specification:
.....


Is this setup even possible, or will I need to relocate the order of the 
disks ?

For my next attempt, I'm going to try to move the ssds to slots 6,7 so 
the boot devices are '0,1' which I know should work.

Failing that, I'll do hardware raid-1 on 0-1 and just a ZFS fs on them 
on top.
