[Wes Morgan]

Are you using grub2 to chainload or booting gptzfsloader directly? I can't
use gptzfsloader directly because it seems to get very confused by the
hybrid GPT MBR needed for booting win7 on a non-EFI laptop.

Re: grub2 with libzfs

[Freddie Cash]

I just recently (last week) converted my "root on USB; data on ZFS" setup
using 2x mirror vdevs to "root-on-zfs". Works beautifully, and can boot off
any of the 4 drives in the pool. Using standard loader and gptzfsboot.

PC-BSD 9.1-p3.

And, I just configured a new storage server at work using FreeBSD 9.1 with
root-on-zfs, using standard loader and gptzfsboot. This one with a single
mirror vdev for the OS, and a separate 7x raidz2 vdev storage pool.

Tab-completion does not detect ZFS.
Will post after I re-compile with latest patch and ZFS-knob disabled per

Hm interesting, does tab-completion list the zfs.es like in

http://imgur.com/a/FUdhs

if you do

grub> set root=(hd0

?  If not can you try again with the latest update

http://people.freebsd.org/~nox/tmp/grub-2.00-006-zfs.patch

with the zfs knob _disabled_ instead of enabled?  (the gentoo zfs
patch made it detect libzfs even w/o needing the base libzfs.h,
maybe the build with the zfs knob enabled is in fact broken?)

grub2 with libzfs

[Beeblebrox]

grub2.0 is installed, but does not have ZFS capability. I go to the grub
command-line and:
grub> ls => (hd0,gpt1) (hd0,gpt2) (hd1,gpt1) (hd1,gpt2) etc...
grub> zfsinfo (hd0,gpt1) => error: could't find a valid label

I have 3 pools but grub finds none of the labels. grub.cfg is loading as
default:
insmod part_gpt
insmod zfs
insmod ufs

I also had to provide "insmod bsd" as default, because grub kept giving me a
'cannot locate bsd.mod' error, it would then become stuck and was unable to
perform any action.

I am currently booting from a temporarily created UFS partition hosting only
/boot.  /boot/grub is on a separate partition as well.

Regards

Re: grub2 with libzfs

[Beeblebrox]

Sam: it goes like this: 

menuentry "FreeBSD Direct-Boot" {
search -s -l zpool
kfreebsd /@/boot/kernel/kernel
kfreebsd_module_elf /@/boot/kernel/opensolaris.ko
kfreebsd_module_elf /@/boot/kernel/zfs.ko
kfreebsd_module /@/boot/zfs/zpool.cache type=/boot/zfs/zpool.cache
kfreebsd_loadenv /@/boot/device.hints
set kFreeBSD.vfs.root.mountfrom=zfs:zpool
}

This is valid if root is on the zfs dataset with the same name as the zpool
- a zfs dataset is created at the same time when pool is created. If root is
on that dataset, this is the syntax.

If root is on another dataset (say pool/myzfsroot) then modify @ with
myzfsroot@ =>
kfreebsd /myzfsroot@/boot/kernel/kernel
kfreebsd_module_elf /myzfsroot@/boot/kernel/opensolaris.ko
etc...

By the way there is a PR to update the grub2 port to 2.00 [1] (that
I also worked a bit on), it doesn't use libzfs yet but it's possible
you only have to add

CPATH=${SRC_BASE}/cddl/contrib/opensolaris/lib/libzfs/common

to CONFIGURE_ENV and MAKE_ENV, and add a ZFS knob to enable this
that checks ${SRC_BASE}/cddl/contrib/opensolaris/lib/libzfs/common/libzfs.h
exists and is off by default because the system sources are not
installed on all systems.  (and possibly fix the plist...)

grub2 with libzfs

[Beeblebrox]

Your Makefile went pretty well for a while - config ran cleanly without any
problems.

>>You're compiling with gcc and use gcc46 include files? 
I have lang/gcc46 installed, but found that many gnu-related ports gave gcc
errors. Then I found the fix like this (until gcc port is modified to
correct the problem): These need to be created, because gcc looks in
/usr/bin:
# ln -s /usr/local/bin/gcc46 /usr/bin/gcc
# ln -s /usr/local/bin/g++46 /usr/bin/g++ 

Back to your script, it finished config then started build but broke at
geom_gettree:

There's something wrong here. You're compiling with gcc and use gcc46
include files?
Anyway I get the same error with grub 1.98 when trying to build with gcc46.

I know that this version can be built with base gcc but the configure
script will expect cc=gcc.
This is not true anymore in 10-current where cc=clang.

So I guess it's broken in 10-current.

I'm sending this to your email so you can grab the tarball.

You are saying that I can also try your tarball, but I thought it was only a
patch to the grub repository. So I'll go ahead and give your
sourcecode+pathc tarball a try and see if it compiles.

Your first post is missing the link to the tarball - can you re-post the
link please?

Thanks.

grub2 with libzfs

[Beeblebrox]

That's what I had hoped for and expected, but the port build fails (that's
why I had contacted the port maintainer Sergey Matveychuk). Build for grub
1.98_1 breaks at:

Is there a way to get around the error?

I'll advise not to start that unless you have a lot of time on your hand.
It took me a few evenings to come up with patches and a working port
so you are warned.

Just build the custom port from the tarball (from my 1st reply)
or use the current FreeBSD port.

Then it should be sufficient to have 'insmod zfs' in grub.cfg. Because grub
doesn't need to know about ZFS before loading its config files.

If I remember well, the 'vanilla' grub 1.98 doesn't recognize ZFS pools
properly. 
This would explain that your Ubuntu version can't see it. There are
patches in
the current FreeBSD port to fix that. These patches were integrated upstream
in later versions.

You definitively don't need '--enable-libzfs'. On FreeBSD, this will
look for some
non-existent include file and fail. This option seems to be used by
folks running
Linux on ZFS.

And just a remark. I think the current version of grub2 in the ports
could be
sufficient for your need. With version 2.00 you gain the ability to
install grub
directly on ZFS, but since you don't use that..

EDIT: I just tried "make" (without the --enable-libzfs) flag for grub 2.0 and
got different error:

grub-2.00 # make
"Makefile", line 20946: Need an operator

line 20946 is:
44: export LC_COLLATE := C
45: export LC_CTYPE := C
46: unexport LC_ALL

Which source are you using?

grub2 with libzfs

[Beeblebrox]

Hi, very happy to see that there are other grub fans in FreeBSD-land!

I was planning to place my grub on a separate UFS partition so that I can
boot other things (like loopbacked iso's) if I should want to. The grub UFS
partition only has grub files in it (what mounts under /boot/grub) and no
kernel files.

>> specify the zfs module if your 'grub-install' target is a ZFS dataset
I forgot to mention my dedicated grub partition, so I hope it clarifies that
my grub-install target is not a ZFS dataset. However, "kfreebsd
/@/boot/kernel/kernel" is on a ZFS dataset.

Other things I forgot to mention:
I booted an ubuntu cd and installed grub 1.98 on the UFS grub partition.
When I drop into the grub command line and "grub> zfslist (hd0) or (hd0,1)"
I get message "no labels found". "insmod zfs" is loaded by default at grub
boot-up.
Host info: 10-Current, amd64, ZFS ver: features async_destroy, empty_bpobj,
lz4_compress

>> You don't need libzfs to use grub2 on ZFS.
Please clarify: Do you mean that I don't need to invoke "--enable-libzfs"?
If so, why do I get the error above (no labels found)?

Thank you for the input & Regards.

Re: grub2 with libzfs

[Christian Mangin]

Hello,

You don't need libzfs to use grub2 on ZFS. You just need to specify the
zfs module if your 'grub-install' target is a ZFS dataset. I've submitted
a patch for this port a while ago, There are probably issues I'm not
aware of but I've been using this custom port for the last 6 months
without problems.

(tarball attached.)

grub2 with libzfs

[Beeblebrox]

I know grub2 is not very popular with the FreeBSD community, but I like it.
Currently the grub2 port looks broken and port maintainer has advised me
that he plans on dropping the port soon. I don't see any point in filing a
PR at this point...

This leaves git/svn trunk from the grub2 download site for ver 2.0.
Unfortunately, when I try to compile I get a libzfs error (seems you must
invoke --enable-libzfs):

./configure --enable-libzfs  ==>
checking for ft2build.h... yes
checking for fuse_main_real in -lfuse... yes
checking fuse/fuse.h usability... yes
checking fuse/fuse.h presence... yes
checking for fuse/fuse.h... yes
checking libdevmapper.h usability... no
checking libdevmapper.h presence... no
checking for libdevmapper.h... no
checking for geom_gettree in -lgeom... yes
checking for lzma_code in -llzma... yes
checking libzfs.h usability... no
checking libzfs.h presence... no
checking for libzfs.h... no
checking libnvpair.h usability... no
checking libnvpair.h presence... no
checking for libnvpair.h... no
checking for libzfs_init in -lzfs... no
configure: error: libzfs support was explicitly requested but
requirements are not satisfied

libzfs is in /usr/lib and libzfs.so.2 is in /lib, but the make process is
looking for libzfs.h.

Any suggestions on how to get this working?

Regards.
