I'm trying to switch a Linux system to FreeBSD. I have two existing
FreeBSD boxes running on the same kind of hardware and my approach was
to rsynch the disk contents from one of those existing configs and just
change the IP configuration in /etc/rc.conf.
After fdisk, disklabel, and newfs for the disks and the rsync for the
data I am left with a system that won't boot. When attempting to boot
from the local disks I can't ping the system anymore, when net-booting
back into rescue mode I see that nothing was written to
/var/messages/log. So, I guess this looks like a bootstrapping problem.
The FreeBSD config that I'm rsynching to the new box is FreeBSD
4.9-RELEASE. Both the existing machine and the new machine have the
same kind of disks in them:
ar0: 117246MB <ATA RAID1 array> [14946/255/63] status: READY subdisks:
0 READY ad0: 117246MB <Maxtor 6Y120L0> [238216/16/63] at ata0-master
PIO4
1 READY ad2: 117246MB <Maxtor 6Y120L0> [238216/16/63] at
ata1-master
The full dmesg output that I get after net-booting from the rescue disk
I included on the very bottom of this message.
Here is what I did before expecting a bootable machine:
#> dd if=/dev/zero of=/dev/ar0 bs=512 count=32
#> fdisk -BI ar0
#> dd if=/dev/zero of=/dev/ar0s1 bs=512 count=32
#> disklabel -w -B ar0s1 auto
#> disklabel -e ar0s1
#> newfs ar0s1a
#> mount /dev/ar0s1a /mnt
...followed by a rsync to /mnt/ from / of the existing machine
...followed by editing the IP configuration in /mnt/etc/rc.conf
...followed by attempting to boot from the local disks
But before I got that far I had some problems for which I found the
following work-arounds:
Initial problem:
#> fdisk -BI ar0
fdisk: can't get disk parameters on /dev/ar0; supplying dummy ones
******* Working on device /dev/ar0 *******
fdisk: invalid fdisk partition table found
fdisk: /boot/mbr: length must be a multiple of sector size
#> disklabel -w -B ar0s1 auto
cylinders/unit 0
#> disklabel -e ar0s1
disklabel: ioctl DIOCGDINFO: Invalid argument
I created a fdisk.conf file as follows:
g c14946 h255 s63
p 1 165 0 240107490
p 2 0 0 0
p 3 0 0 0
p 4 0 0 0
a 1
...and tried:
#> fdisk -f ./fdisk.conf ar0
fdisk: can't get disk parameters on /dev/ar0; supplying dummy ones
******* Working on device /dev/ar0 *******
fdisk: invalid fdisk partition table found
fdisk: /boot/mbr: length must be a multiple of sector size
I net-booted into the alternative Linux-based rescue disk and did the
following with both fdisk /dev/hda and fdisk /dev/hdc in order to get
rid of the existing Linux partitioning and setup:
Created a new empty DOS partition table:
Disk /dev/hda: 255 heads, 63 sectors, 14946 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 1 14946 120053713+ a5 FreeBSD
And created a bsd disklabel:
Reading disklabel of /dev/hda1 at sector 64.
/dev/hda1 contains no disklabel.
Do you want to create a disklabel? (y/n) y
# /dev/hda1 :

d: 1 14946 14946 unused 0 0
Then I net-booted back into the FreeBSD-based rescue mode and still got
stuck first on "fdisk -BI ar0" but this time was able to do "fdisk -f
./fdisk.conf ar0":
#> dd if=/dev/zero of=/dev/ar0 bs=512 count=32

#> disklabel -w -B ar0s1 auto

I edited the disklabel and changed it from:

...to the config I'm successfully using on other boxes:

After that I was able to construct a new file system:

And I was able to mount it and rsynch the disk contents from a matching
existing freebsd machine (FreeBSD 4.9-RELEASE).

I edited /mnt/etc/rc.conf to change the ifconfig to the different IP
address.
But attempting to boot from the local disks fails. I can't ping the
machine anymore and don't know where it is hanging since I only have
remote access. After net-booting back into the rescue mode it doesn't
look like anything was written to /mnt/var/log/messages during the
local boot attempt.
How do I verify that the bootstrapping is configured right? Or where
else am I going wrong?
Thanks for any tips!
Chris
