Migrate FreeBSD From One Harddrive To Another

General Information

This guide will explain how you can move your FreeBSD installation from one hard disk drive to another. nike air max nike air max pas cher nike air max 90 adidas yeezy timberland pas cher timberland soldes I have done this many times using the dump/restore utility. ugg australia classic Soldes 2017 Asics nike air max 2014 adidas stan smith femme nike air max ugg pas cher Before you begin, be sure you have read this document carefully.


Requirements

  1. Root Access or Sudo Rights.
  2. A List of Your Old and new Hardrive Information like /dev/ad* /dev/da* /dev/sd* and so on this can be checked by doing cat /var/log/messages and read the disctypes that come along.

Configuration

Let’s assume that our FreeBSD installation is on a 4 gigabyte drive (ide master ad0) and we would like to move it to a new 20 gig drive.

What you need to do is remove the old hard disk, install the new [20G] drive as an ide master and perform a minimal clean install of FreeBSD, setting up the partitions exactly how you want them. nike air max tn soldes new balance france asics soldes nike free run nike roshe run new balance 574 Be se sure to set the drive as bootable and boot from it one time as a test.

Next, put your old [4G] drive back in the system as an ide master and the new [20G] drive in as an ide slave. ugg homme ugg boots bailey bow adidas nmd adidas zx flux pas cher asics whizzer timberland femme Boot the system on your old installation in single user mode.

To boot in single user mode press 4 at the 10 second countdown.

At the (#) prompt type:

 # fsck -p # mount -u / # mount -a # swapon -a # adjkerntz -i 

Next, make sure you have the device files made so you can mount the partitions on the slave drive.

 # cd /dev # ./MAKEDEV ad1s1a # ./MAKEDEV ad1s1e # ./MAKEDEV ad1s1f 

Now make mount points for the new drive’s partitions:

 # mkdir /backup # mkdir /backup/root # mkdir /backup/usr # mkdir /backup/var 

Lastly, I use a shell script to do the following:

  1. create new filesystems (newfs the drive)
  2. mount the partitions
  3. dump the data from my old drive, and restore it to my new one
  4. unmount the new drives partitions
  5. enable softupdates on the new drive (optional)

Here is the script I use:

 #!/bin/sh newfs /dev/ad1s1a newfs /dev/ad1s1e newfs /dev/ad1s1f mount /dev/ad1s1a /backup/root mount /dev/ad1s1e /backup/var mount /dev/ad1s1f /backup/usr ( dump -0f - / ) | ( cd /backup/root ; restore -rf - ) ( dump -0f - /var ) | ( cd /backup/var ; restore -rf - ) ( dump -0f - /usr ) | ( cd /backup/usr ; restore -rf - ) umount /backup/root umount /backup/var umount /backup/usr tunefs -n enable /dev/ad1s1a tunefs -n enable /dev/ad1s1e tunefs -n enable /dev/ad1s1f #end 

It will probably take several hours to perform the dump/restore, so be patient. nike tn louboutin chaussures ugg homme soldes nike air max pas cher adidas zx 500 Nike Roshe Run soldes Once the data has been dumped and restored to the new drive, all you have to do is remove your old drive and put it in a safe place, set the new drive to a master and reboot.
