A way to transfer drives?

A way to transfer drives?

[1stFlight]

 I'm looking for a way to upgrade my HD and maintain file/directory structure. 
I've got a 20GB  with partitions for / /home /usr how can I copy/clone this 
drive over to it's 60B replacement? Thanks!

Connect the new drive in place as the secondary. 
Boot as normal. 
Use fdisk as appropriate on the new drive to set up your partitions as
you want them.
Create file systems on the partitions you have created using whatever
file system you are using (eg Ext3). This does not have to be the same
as the previous FS you used.

To copy from one place to another (including sub-dirs) you can use find
and cpio like this:

cd <wherever you are copying _from_
find . -print | cpio -pmudv <wherever you want to put the files>

eg:

cd /usr
find . -print | cpio -pmudv /mnt/newusr


To do root, you can use grep in between the commands:

cd /
find . -print | grep -v newdisk | cpio -pmudv /mnt/newdisk

Excuse the confusion, I wasn't thinking straight. In my examples below,
the < and > are not intended to be used in the command - I just meant to
highlight the source / destination descriptions.

Hi

just finished this  operation last night .
setup :

boot from /dev/hda

/dev/hdb - 40GB (old disk)
/dev/hdc - 60GB (new disk )

# dd if=/dev/hdb of=/dev/hdc bs=2M

it did a perfect,bit by bit, clone . then, i used cfdisk to set up an 
additional 20Gb partition for the extra space.

works like a charm .

i always set bs (block size) close to the size of the HDD buffer (2048 
in my case)

hope it helps.

This does, however, have the disadvantage that your existing partitions
are copied but not resized. Eventually, you end up with lots of little
partitions (after a couple of hard disk upgrades...)

you are absolutely right. I allready lost the old  256 MB swap 
partition. (unsable space). I never do this twice.

I wouldn't copy/clone it, I'd make new partitions in proportion, mount
them on new temporary mount points (make  some with mkdir if you
don't have some handy) and use tartar to copy the
filesystems:
tartar / /newslash
tartar /home /newhome
.....

tartar is what I call it, I chose the tar options for just such a use

#!/bin/bash
##copy a directory or partition
tar -C "$1" -cOl . | tar -C "$2" -xpf -


You could use cpio or cp or what you like instead, that is just the way
I would do it.
Some time ago somebody wondered why this did not copy everything in / -
it's not meant to,

Don't forget to reinstall lilo or whatever bootloader you use after
you get the new hd mounted where it is going to go.  have a boot floppy
handy.  You can install lilo in one place to make it work in another,
but I'm not up to explaining how.

That's an idea, but I believe parted should be much faster.
I think compressing and decompressing would be a little bit slow ?

It's not compressing and decompressing.  Tar only does that if you tell
it (with an option I,y,z,Z or the corresponding long names or
--use-compress-program).  Saving and restoring this way will also
defragment the filesystem.

There is only one snag with tartar: it doesn't pick up 'dot' files in
the starting directory.

If you mean files of the form .name, I can't see that it doesn't.
ls won't show them without -a though.

Re: A way to transfer drives?

[Paul Furness]

My apologies, you are correct. I think my brain stepped out for a
moment... :)

To be exact: if you tar using a directory name, it works fine, but if
you use a wild card it doesn't see dot files (because that's how
wildcard expansion works).

thus:

cd $HOME
tar -cvf /archive/homedir.tar *

will not do the same as:

cd $HOME
tar -cvf /archive/homedir.tar .

The first example will not save anything who's name begins with a dot,
but the second one will.


A thing to know about:

cd /
tar -cvf /archive/homedir.tar $HOME

will store the full path of everything in your home dir. This means that
if you try and extract it later on, it will try and put all the files
back _exactly_ where they came from in the first place.

Although this sounds like a fine idea for a backup, I have found that it
makes more sense to avoid the full paths for user generated data,
because there will always be the time when you want to get back the
backup and compare it to what you already have - which is much more
complicated if you have the full paths stored in the archive.

It also means that restoring the stuff to a different machine is harder,
because you need an identical directory structure - less of a problem
with a home dir, but it could be something more complicated like this:

tar -cvf /archive/backup.tar /usr/local/data/bungle/source/c/big_project

Paul.
