Hi,
I've just performed a fresh install of 11.2: 11.2-RELEASE FreeBSD
11.2-RELEASE #0 r335510: Fri Jun 22 04:32:14 UTC 2018
Basically as I have a custom partition layout I decided to install ZFS
on Root manually.
# gpart show ada0
=> 40 468862048 ada0 GPT (224G)
40 1024 1 freebsd-boot (512K)
1064 2097152 2 freebsd-swap (1.0G)
2098216 14679256 - free - (7.0G)
16777472 233292168 3 freebsd-zfs (111G)
250069640 218792448 4 freebsd-zfs (104G)
This is mirrored with ada1 in the zroot:
# gpart show ada1
=> 40 468862048 ada1 GPT (224G)
40 1024 1 freebsd-boot (512K)
1064 2097152 2 freebsd-swap (1.0G)
2098216 14679256 - free - (7.0G)
16777472 233292168 3 freebsd-zfs (111G)
250069640 218792448 4 freebsd-zfs (104G)
The zpool has been constructed as such:
# zpool status zroot
pool: zroot
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
zroot ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
ada0p3 ONLINE 0 0 0
ada1p3 ONLINE 0 0 0
errors: No known data errors
As there seems to be little documentation on customized or manual
install of ZFS on root as the installation medium partitioner utilizes
the whole disk, I am a little lost!
The information on the Fbsd wiki:
https://wiki.freebsd.org/RootOnZFS/ZFSBootPartition is outdated and
later steps are not relevant any more as there is no more 'sysinstall'.
The steps I followed are off a thread in the forum:
https://forums.freebsd.org/threads/installing-freebsd-manually-no-installer.63201/
This works so long as I boot the kernel from my installation USB drive
using the steps:
ok unload
ok load /boot/kernel/kernel
ok load /boot/kernel/opensolaris.ko
ok load /boot/kernel/zfs.ko
<any extra modules> <-- for me iscsi.ko, if_lagg.ko, iscsi_initiator.ko,
ctl.ko, cfiscsi.ko
ok set vfs.root.mountfrom="zfs:zroot"
ok boot
Now if I try to boot directly from the system (I have already installed
the kernel and issued: gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot
-i 1 ada(x) for both drives ada0 & ada1)
the system I think at Boot Stage 2? following:
https://www.freebsd.org/doc/handbook/boot-introduction.html
comes up with:
BIOS drive [...]
read 264 from 384 to 0x7c0f5f80 .... until final message: error: 0x10
Then finally shows the Beastie pic with menu which I think is Stage 3?
then boots the kernel.
I get messages complaining about some /dev devices not being accessible
or writable then it complains about not being able to read the
/etc/defaults/devfs rules file.
Afterwards I see the standard kernel messages until the date/time is
shown after which the boot process hangs and no login prompt appears.
Is there anyone who is familiar with the boot process who can help me
out here....?? I'm not sure if I missed configuring something in the
boot loader or if I need to map /dev to the system or something.....
Anyway, it is a fresh install so nothing I think is corrupted, as the
pool is fine. Just something to do with booting and loading things I think??
Many thanks in advance.
Kaya
