The problem I have Im sure is common one but I have found no
answers to this in the handbook.
situation: have a server with boot drive thats getting old, want to copy
the entire boot drive and boot records to the new drive and replace the drive.
I can not take the server down to do the dos program drive image or ghost.
( I want to do this with having to use any dos programs, free myself from
bill )
the problem is the server Im going to clone is in a different location than
I am
I want to have everything ready to just walk in and add the drive.
so this is what I have done.
made a dump file of the old boot drive
dump -0ua -f /tmp/backup/boot.dump /dev/wd0s1a
gzip boot.dump and ftp'd it to my local workstation.
( I would have liked to done dump | retore over tcp but I dont know to )
I then added a new hd to my workstation.
cd /stand
sysintall
post configuration
fdisk
I selected the new drive on mine was ( ad2 )
in the fdisk menu I picked "a" ( entire disk )
then I picked "s" ( make bootable)
picked "w" to write the info to the disk
I picked standard boot manager
disk label
picked "c" create new slice
added /dev/ad2s1b none swap
/dev/ad2s1e /mnt ufs
"w" wrote the update, it ran fsck and mounted my new drive to /mnt
I then
cd /mnt
cp /tmp/boot.dump.gz .
gunzip boot.dump
restore -rf boot.dump /dev/ad2s1e
after restore was done I went and changed the /mnt/etc/fstab
commented out the other drive from the old server and add
/dev/ad0s1b none swap
/dev/ad0s1e / ufs
then did a shutdown and removed new hard drive, put the drive in
a new system and booted it.
the screen says
invalid partition
invalid partition
no /boot/loader
defualt: 0:ad(0,a)/kernel
boot:
invalid partition
no /kernel
so I type this in
0:ad0(0,e)/kernel
panic: rslock: cpu: 0, addr: 0x02c3770, lock: 0x00000001
mp_lock = 00000001; cpuid = 0; lapic.id = 0000000
automatic reboot in 15 sec
the kernel was for a multi cpu server and I was trying to boot on a single
cpu. so I tried
0:ad0(0,e)/kernel.old
and it booted with the old single cpu kernel.
( I will be using the multi cpu kernel when I install the new hd back
into the real server)
now Im lost at how to change it so it boots to
0:ad(0,e)/kernel when it picks ad(0,a)
I though I do it with command fdisk but I didnt understand what I should
do.
If there is something I have not done correctly please let me know.
or if there is a better and faster way to do this.
once I know how all of this works and fits together I would like to
get it added to the How-to to help other people and credit who help
in completion of this.
Thank you for your help
Tony
