 ====== Copy Linux to a new Harddisk ======
+In the following howto i assume that sda is your source drive and sdb is your target drive.. please make sure not to mix this up in your setup! also i assume that your operating system disk has three partitions, sda1 as /boot, sda2 as swap and sda3 as /
-  * stop any running services like apache, mysql etc. on the source system.
+  * stop any running services like apache, mysql etc. on the source system. or even better, boot from a live linux and work from there..
   * partition and format the new harddisk
-  * rsync - for each partition
+    * parted /dev/sda --> print shows the current partitions of sda including their sizes.. that should help :)
-  * edit fstab and /boot/grub/menu.lst and update UUID according to [[harddisks_by_uuid_in_debian_lenny]]
+  * create mountpoints for source and target <code>mkdir /tmp/source
-  * install grub
+mkdir /tmp/target</code>
-  sudo grub
+  * mount source and targed partitions: <code>
-  find /boot/grub/menulst
+mount /dev/sda3 /tmp/source
-(if you have an own partiton for boot, you can leave boot away in the above command)
+mount /dev/sda1 /tmp/source/boot
-  root (hd0,0)
+mount /dev/sdb3 /tmp/target
-  setup (hd0)
+mkdir /tmp/target/boot
+mount /dev/sdb1 /tmp/target/boot
+</code>
+  * now copy the os: <code>rsync -aHvx --numeric-ids /tmp/source /tmp/target</code>
+  * edit /tmp/target/etc/fstab and /tmp/target/boot/grub/menu.lst and update UUID according to [[harddisks_by_uuid_in_debian_lenny]]
+  * chroot to the target drive and install grub: <code>
+mount --bind /dev/ /tmp/target/dev
+mount --bind /sys/ /tmp/target/sys
+mount --bind /proc/ /tmp/target/proc
+chroot /tmp/target
+grub-install /dev/sdb
+update-grub
+grub
+find /boot/grub/menulst</code>(if you have an own partiton for boot, you can leave boot away in the above command) <code>
+root (hd0,0)
+setup (hd0)
+</code>
+  * if you are moving your installation to new hardware (other than just the harddisk) you might need to update your initrd image to contain the necessary drivers (i.e. in redhat based systems). run ''dracut''
   * reboot your system
