Please help.
I performed a
freebsd-update -r 8.2-RELEASE upgrade from my 7.2-RELEASE FreeBSD 7.2-RELEASE #0 server.
After that, I did
freebsd-update install,
reboot,
freebsd-update install again, and
reboot.
( all that by SSH )
BUT, I had the brilliant idea to do:
freebsd-update -r 9.2-RELEASE upgrade in sequence.
Result: no boot any more.
So, with help of
http://mfsbsd.vx.sk/ I was able to boot from USB and I can mount my disks.
I tried:
Code:
cd /mnt/boot
mv kernel kernel.bad
mv kernel.old kernel
reboot
=== no luck
I tried:
Code:
mv kernel kernel.old
mv kernel.old1 kernel
reboot
=== no luck
I also tried:
Code:
- create a virtualbox machine with FreeBSD 7.2-RELEASE
- made a copy of the folder "/boot" from virtualbox
tar -cz -f /usr/local/www/boot72.tgz /boot
- unpack the virtualbox folder into the "/boot" of my broken server
cd /mnt/boot
rm -rf *
fetch http://192.168.56.11/boot72.tgz
tar -xvf boot72.tgz
rm boot72.tgz
reboot
=== no luck either
Please help what can I do now?
Is there a way to put a new kernel without loose my data?
I got my broken server running again, so, I'll post here what I did:
Download install iso from:
http://ftp-archive.freebsd.org/pub/...MAGES/8.2/FreeBSD-8.2-RELEASE-amd64-disc1.iso
1) CREATE A VIRTUAL BOX MACHINE WITH FreeBSD-8.2-RELEASE:
- 1024Mb RAM
- 8Gb Hd
- Network adapter #1 = NAT
- Network adapter #2 = Host Only
- CDROM pointed to FreeBSD-8.2-RELEASE-amd64-disc1.iso
Start
Code:
- 1 Boot FreeBSD [default]
- Country Selection: 232 United States
- Express (beguin a quick installation)
- FDisk Partition Editor:
-- A (use entire disk)
-- Q (finish)
- Install Boot Manager:
-- Standard
- FDisk Disk Label Editor:
Code:
-- C (create) 1024M (enter) FS (enter) / (enter)
-- C (create) 1024M (enter) Swap (enter)
-- C (Create) <full remaining size> (enter) FS (enter) /usr (enter)
-- Q (finish)
- Choose Distribuitions
Code:
-- (space) [x] Developer, [x] en, with ports
-- (space) [x] Kernel, [x] en, with ports
-- (space) [x] User, [x] en, with ports
-- <<< Exit
-- CD/DVD (enter)
-- "Last chance! Are you SURE you want continue the installation?"
-- [ Yes ]
- Visit the general configuration menu for a chance to set any last options?
Code:
-- [ Yes ]
-- Root Password
-- User Management, Add User
-- Login ID: john UID: 1001 Group: (blank)

-- Extra options: (enter)
-- [ OK ]
-- <<< Exit
-- (up) (up) (up)
-- X Exit
- [ X Exit Install ]
- Are you sure you wish to exit? The system will reboot.
[ Yes ]
( Devices: remove CDROM )
2) COPY FILES FROM VIRTUAL MACHINE TO SOME FTP SERVER:
- Logon to virtualmachine
Code:
mkdir /home/john/82
cd /home/john/82
# create compressed files to export
Code:
tar -cz -f boot.tgz /boot
tar -cz -f usr-lib.tgz /usr/lib
tar -cz -f usr-libexec.tgz /usr/libexec
tar -cz -f usr-obj.tgz /usr/obj
tar -cz -f usr-sbin.tgz /usr/sbin
tar -cz -f usr-src.tgz /usr/src
tar -cz -f usr-bin.tgz /usr/bin
tar -cz -f usr-include.tgz /usr/include
tar -cz -f usr-libdata.tgz /usr/libdata
tar -cz -f usr-share.tgz /usr/share
tar -cz -f usr-local-bin.tgz /usr/local/bin
tar -cz -f usr-local-include.tgz /usr/local/include
tar -cz -f usr-local-lib.tgz /usr/local/lib
tar -cz -f usr-local-libexec.tgz /usr/local/libexec
tar -cz -f usr-local-sbin.tgz /usr/local/sbin
tar -cz -f usr-local-info.tgz /usr/local/info
tar -cz -f usr-local-libdata.tgz /usr/local/libdata
tar -cz -f usr-local-man.tgz /usr/local/man
tar -cz -f usr-local-share.tgz /usr/local/share
# Send files to a ftp
Code:
ftp ftp://john@someserver.com
mkdir 82
cd 82
mput *
3) COPY FILES FROM FTP SERVER TO MY BROCKEN SERVER:
- Logon to my broken server using the live boot usb from
http://mfsbsd.vx.sk/
Code:
1) Download the image for USB PENDRIVE:
http://mfsbsd.vx.sk/files/images/9/amd64/mfsbsd-9.2-RELEASE-amd64.img
2) Download the windows programa to write the pendrive:
http://sourceforge.net/projects/win32diskimager/
3) Boot my broken server from PENDRIVE.
4) Logon on my broken server using the mfsbsd:
root@mfsbsd:~#
User: root
Pass: mfsroot
5) Configure the IP, default route and DNS:
ifconfig bce1 123.123.123.123 netmask 255.255.255.0
route add 0.0.0.0 123.123.123.1
echo nameserver 8.8.8.8 >> /etc/resolv.conf
- Mount my "/" and "/usr" partitions on broken server:
Code:
ls /dev/
mount /dev/mfid0s1a /mnt
- If happens some error asking to run fsck, use:
Code:
fsck_ffs -f /dev/mfid0s1a
mount /dev/mfid0s1a /mnt
- In /mnt-usr let's mount my /usr
Code:
mkdir /mnt-usr
mount /dev/mfid0s1e /mnt-usr
- Download files of Virtual FreeBSD-8.2 from ftp
Code:
cd /mnt-usr/home/john
mkdir 82
cd 82
ftp ftp://john@someserver.com
cd 82
mget *
quit
- Extract files do local 82 folder
Code:
ls
tar -xvf boot.tgz
tar -xvf usr-lib.tgz
tar -xvf usr-libexec.tgz
tar -xvf usr-obj.tgz
tar -xvf usr-sbin.tgz
tar -xvf usr-src.tgz
tar -xvf usr-bin.tgz
tar -xvf usr-include.tgz
tar -xvf usr-libdata.tgz
tar -xvf usr-share.tgz
tar -xvf usr-local-bin.tgz
tar -xvf usr-local-include.tgz
tar -xvf usr-local-lib.tgz
tar -xvf usr-local-libexec.tgz
tar -xvf usr-local-sbin.tgz
tar -xvf usr-local-info.tgz
tar -xvf usr-local-libdata.tgz
tar -xvf usr-local-man.tgz
tar -xvf usr-local-share.tgz
- Copy the 82 files to my broken server folders
Code:
cp -Rp /mnt-usr/home/john/82/boot/* /mnt/boot/
cp -Rp /mnt-usr/home/john/82/usr/* /mnt-usr/
- Revise the rc.conf and rc.firewall of broken server
Code:
cd /mnt/etc
ee rc.conf
ee rc.firewall
- And now...
