[zfs-discuss] ZFS Boot Won''t work with a straight or mirror zfsroot

Using build 70, I followed the zfsboot instructions at http:// 
www.opensolaris.org/os/community/zfs/boot/zfsboot-manual/  to the  
letter.

I tried first with a mirror zfsroot, when I try to boot to zfsboot  
the screen is flooded with "init(1M) exited on fatal signal 9"

Than I tried with a simple zfs pool (not mirrored) and it just  
reboots right away.

If I try to setup grub manually, it has no problem in both cases  
finding the root_archive, etc...:

grub> root (hd0,0,a)
  Filesystem type is zfs, partition type 0xbf

grub> /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS
loading ''platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS
cpu: ''AuthenticAMD'' family 15 model 47 step 0
[BIOS accepted mixed-mode target setting!]
   [Multiboot-kluge, loadaddr=0xbffe38, text-and-data=0x161958,  
bss=0x0, entry=0xc00000]
''/platform/i86pc/kernel/amd64/unix -B zfs-bootfs=rootpool/21''
is loaded

grub> boot

Any idea what I am doing wrong?

Thanks and regards

This is everything I did:

# root is about 350 megs ... so it should fit nicely on our flash disk.

# let''s make separate partition for /, /var, /opt, /usr and
/export/home

# Later we''ll move / to the separate disk (in this case a zfs mirror  
pool)
# and we will create a raidz2 pool for /var, /opt, /usr and /export/ 
home... so we won''t have to worry much about the size
# of these volumes.
# finally we''ll create a zvol for swap this machine has really a lot  
of ram so I don''t really worry about swapping.

# So we Modify c0t0d0... and create:

# 0 / 1024M
# 1 swap 518M
# 2 /usr 10240M
# 3 /var  10240M
# 4 /opt  10240M
# 7 /export/home ... whatever is left

formatted my flashdisks with 2 identical unamed slices (s0) of 969M

Installed everything on that temporary install disk (c0t0d0)

zpool create -f datapool raidz2 /dev/dsk/c4d0  /dev/dsk/c5d0  /dev/ 
dsk/c6d0  /dev/dsk/c7d0

[zfs-discuss] ZFS Boot Won''t work with a straight or mirror zfsroot

I just tried again with Tim Foster''s script ( http:// 
mediacast.sun.com/share/timf/zfs-actual-root-install.sh ) and I get  
the same negative results...

with mirror c1t0d0s0 c2t0d0s0, I get "init(1M) exited on fatal signal  
9" spam.
with a straight c1t0d0s0, I get the same problem...

I tried with 2 Sandisk U3 Cruser USB drive (in mirror mode and single  
disk )... I also tried with a Kingston because I was worried the U3  
and emulated cd was causing problem... but got same result

If I remove the original UFS boot disk, there is a panic message  
after the Solaris Version header... but it just flashes and reboot  
before I have the time to read it...

Otherwise if I keep the original UFS boot disk, I get the init(1M)  
existed on fatal signal 9 crap.
I am going to try one more time with a real harddisk instead of a UFS  
boot disk.

Lori told me in a private e-mail that the mount root was a hack..  
well I prefer a hack that worked than this nightmare.
I would really prefer having a minimal ufs boot and mount my raidz2  
rootfs than wasting days to make zfs boot work as expected!

That''s the thing, zfs mountroot worked perfect any support for it was  
taken out in build 62... great backward compatibility here!

No - but I''ll post my (very ugly) ZFS boot "cheat sheet"
that''ll get
you up and running, from scratch, in less than one hour.  Apologies 
for the nastiness of this cheat sheet - I''ll pretty it up and post it 
later.

# this "cheat sheet" makes the following assumptions:

# The install server is at 192.168.80.18
# The install server is using a ZFS based filesystem with 
# a pool called tanku.  The users home directory is also
# in this pool at /tanku/home/al
# the target machine has ethernet address: 00:e0:81:2f:e1:4f

# verify that your ethernet interface supports PXE boot
# most systems do - except for low-end ethernet cards that
# don''t have an option RAM
# verify that you know which two disks you''ll be loading the
# OS to.  If need be, you''ll have to boot the box off a DVD
# and run format to determine the available disk drives

# determine the ethernet address of the interface you''ll be
# using for PXE boot.  See more notes below.  Make a note 
# of it.

# next: download Lori Alts/Dave Miners ZFS boot tools:

wget
http://www.opensolaris.org/os/community/install/files/zfsboot-kit-20060418.i386.tar.bz2

# Yes - the date should be 20070418
# unzip and untar them - in this case they''ll end up in
# /tanku/home/al/zfsboot/20070418 (aka ~al/zfsboot/20070418)
# Find and read the README file.  But don''t spend too much
# time studying it.  The cheat sheet will tell you what to do.

# on the install server setup a ZFS bootable netinstall image for b72
mkdir /mnt72
chown root:sys /mnt72
chmod 755 /mnt72
# FYI only: /solimages is an NFS mount
lofiadm -a /solimages/sol-nv-b72-x86-dvd.iso
# assumes that lofiadm returned "/dev/lofi/2"
mount -F hsfs -o ro /dev/lofi/2 /mnt72
zfs create tanku/b72installzfs
zfs set sharenfs=''ro,anon=0'' tanku/b72installzfs
cd /mnt72/Solaris_11/Tools
./setup_install_server /tanku/b72installzfs
cd /tanku/home/al/zfsboot/20070418
# next step takes around 13 minutes (why?)
ptime ./patch_image_for_zfsboot /tanku/b72installzfs
# remove the DVD image mount and cleanup
umount /mnt72
lofiadm -d /dev/lofi/2

# verify that you can mount /tanku/b72installzfs on another machine
# as a quick test.  Best to check this _now_ than try to figure it
# out later.
# mount -F nfs -o ro,vers=3,proto=tcp 192.168.80.18:/tanku/b72installzfs /mnt
# go to the prepared zfs boot area (in this case /tanku/b72zfsinstall
cd /tanku/b72installzfs/Solaris_11/Tools

# add the install server files
./add_install_client -d -e 00:e0:81:2f:e1:4f -s
192.168.80.18:/tanku/b72installzfs  i86pc

# you''ll see instructions to add the client macros (something) like:

     If not already configured, enable PXE boot by creating
     a macro named 0100E0812FE14F with:
       Boot server IP (BootSrvA) : 192.168.80.18
       Boot file      (BootFile) : 0100E0812FE14F

# using: the screen-by-screen guide at: 
# http://www.sun.com/bigadmin/features/articles/jumpstart_x86_x64.jsp
# starting at step 5:
#             ^^^^^^
# 5. Configure and Run the DHCP Server
#
# add the two macros and use the name 0100E0812FE14F

# NB: Ignore *all* the stuff up to step 5.  You don''t need any of it!

# NB: the macro must have the correct name
# verify that the tftp based files are available

df |grep tftp

# it should look something *like* this:
#/tanku/b72installzfs/boot
#                     260129046 3564877 256564169     2%   
/tftpboot/I86PC.Solaris_11-2

# test that the tftp files can be retrieved via tftp:

cd /tmp
tftp
> connect 192.168.80.18
> get 0100E0812FE14F
> quit
# enable FTP on your boot server to allow snagging the zfs boot profile file:

svcadm enable ftp

# change your password before you dare use ftp.  Remember to use a disposable
# password - because it can be sniffed on the LAN.  After we''re done
with FTP,
# restore your original password.

# enable the PXE boot on the target systems BIOS

# boot the target machine
# during the early phases of booting press F12  ASAP

# you should see the machine contact the DHCP server and start downloading
# the required files within a couple of seconds.

NB: verify that the ethernet address displayed by the PXE code is the same one
you expected and is associated with the physical interface in use.  Some
machines
pick the ethernet port that will be used for PXE boot for you - you
don''t have a
choice.  Newer BIOSes allow you to enable PXE separately for each supported
interface.

expect to see a GRUB prompt for the release you''re installing (i.e.,
b72)

Select 4 (Console install) - its the least likely to cause you issues.
If you''re using bge0 as the PXE boot interface, ensure that you leave 
the bge0 interface enabled for networking  "[x] bge0" - otherwise you 
won''t be able to "see" the install server.

Fill in the minimum required config details, and take the first EXIT option
as soon as you see one.  Now you''ll have a command line prompt.

# the following assumes you''ve setup a profile file called (simply) 
# profile.zfs on your boot server.  See samples below.
# At the prompt:

cd /tmp
ftp 192.168.80.18
user:
password: (use the dummy password you setup earlier)
get profile.zfs
quit

# Now load the system with pfinstall

pfinstall /tmp/profile.zfs

# the system should begin loading Solaris within a couple of Seconds.

Your source root filesystem is on UFS?

I think much of the above steps could be simplified by populating
the zfs root filesystem like this:

    mount -F zfs rootpool/rootfs /zfsroot
    ufsdump 0f - / | (cd /zfsroot; ufsrestore xf -)
    umount /zfsroot

That way, you don''t have to use the "create_dirs" script,
or mess with the /devices and /dev device tree and the
lofs mount.

Using ufsdump/ufsrestore also gets the lib/libc.so.1 file correct
in the rootfs zfs, which typically has some lofs file mounted on
top of it.

[zfs-discuss] ZFS Boot Won''t work with a straight or mirror zfsroot

Thanks J?rgen,

I was hit by 6423745 (see below) but the main problem is that /sbin/ 
zpool is linked to /usr/lib/libdiskmgt.so.1 and since /usr was on my  
datapool, it failed systematically.

I don''t think it makes sense that an executable in /sbin be linked to  
a lib in /usr/lib. The only binaries in /sbin linking to /usr/lib are  
zpool and zonename.

Shall I move libdiskmgt.so.1 to /lib ? or  will that break something  
else?

Thanks ... It seems one of the problem was bug 6423745, thanks for  
pointing that.
The first time I created the zpool it was during install and for some  
reason the installation is done in 32 bit mode.
Someone should also correct the zfs boot manual ( http:// 
www.opensolaris.org/os/community/zfs/boot/zfsboot- 
manual/;jsessionid=DE41DAFDD945D813FDD8FBAEC669BD11 ) because the  
grub entry is missing $ISADIR and will cause to always boot in 32 bit  
mode.

using ufsrestore works for /var and /opt but failed for /usr, nothing  
was copied when

Creating a usr/lib directory and copying the libdiskmgt.so.1 there  
would probably provide a temporary fix...

I''ll try it tomorrow... if it works I can finally boot my zfs root  
partition two mirrored USB flash drives instead of these 2 slow and  
ugly 10G IDE drives I grabbed from some old xboxes.
