booting from separate zfs pool

[Eugene M. Zheganin]

Hi.

So, I'm still struggling with my problem when I cannot boot from a big
zfs 2T pool (I have written some messages about a year ago, the whole
story is too long and irrelevant to retell it, I'll only notice that I
took the path where I'm about to boot from a separate zfs pool closer to
the beginning of the disk).

I've created such a smaller pool, called it zboot. I've read pjd@ letter
explaining that when FreeBSD sees several bootable pools, it chooses the
first one - that's fine with me, since the new pool partition's number
is smaller than the big one. So, I created zboot, set the mountpoint to
legacy, wrote the content to it's /boot directory (and yes, I did call
the 'make installkernel DESTDIR=/zboot') and rebooted. Strage thing
happened next - I got


Can't find /boot/zfsloader

FreeBSD/x86 boot
Default: zboot:/boot/kernel/kernel
boot:
|
Can't find /boot/kernel/kernel


I booted back from USB stick (that I'm using to boot my machine) and
rechecked these files - everything mentioned here is in it's place.

Does someone have the idea what I'm doing wrong ? May be this has
something to do with the fact that zboot does contain only the /boot
directory, and not the full rootfs ?

Thanks.
Eugene.

it's no an answer to your question, but I'm wondering wether the solution
to this may also help with beadm being unable to work with crypted ZFS root

I would not use the root dataset. Create a ROOT/ one so it looks for
the kernel in "zboot:/ROOT/fist/boot/kernel/kernel" or similar. This way
you are compatible with beadm.

I think the new pivotroot type stuff in 11 may help a lot with this

I thought that was in 10.3 as well?

And of course, dataset zboot:/ROOT/fist in above example should set as
bootfs by

 #zpool set bootfs=zboot/ROOT/fist zboot

and mountpoints of zboot and zboot/ROOT should be set to NONE by

 #zfs set mountpoint=none zboot
 #zfs set mountpoint=none zboot/ROOT

respectively. Otherwise, boot would fail. When I forgot to set bootfs,
got boot failure, even I've set vfs.root.mountfrom in /boot/loader.conf
properly. Are these OK?

# This is easily forgotten on manual installation. :-<

Re: booting from separate zfs pool

[Tomoaki AOKI]

And with this feature, if I understood correctly, old kernel keeps on
running after this type of reboot.
If so, kernel modules loaded via /etc/rc.conf[.local] can cause version
mismatch with running kernel, forcing single user mode.

So I'd prefer making 'zboot' pool as real rootfs and mount needed
datasets from main pool. (Use povot-root only for userland-only
updates.)

# Pivot-root would be similar to configuration below. Right?

   *Use UEFI loader of 10.3 or later
   *UFS having /boot
   *ZFS NOT having /boot (at least, /boot/loader.efi)
   */boot/loader.conf has vfs.root.mountfrom line pointing inside ZFS

  Below can be optional.
   *UFS is mounted to some mountpoint such as /ufsboot after boot
   *ZFS has symlink /boot pointing /ufsboot

FWIW, I'm booting the kernel off a different pool from where the rootfs
is... I've set bootfs on the boot-pool (to point to itself), and the
loader.conf in that boot pool has vfs.root.mountfrom point to the
root-fs on the other pool.
