Hi.
As you know, when you make a backup of a full disk using DD, it include the size disk of the source.

So, let's imagine to made a backup of a 10GB Disk.

If you restore that image to a 1TB Disk, this 1TB disk will be transformed to a 10GB disk.

So, How can I expand the disk to it real size?

I use lvm:

This is my out put

Please, post me the easy way to do it.

Thanks

How about doing everything you describe above and then using gparted to expand the size of the disk (partition)?

The system doesn't have X.
I'm not physically in the client office, i'm working remotly.

GParted has a non-graphical version, Parted.

I found this thread, which appears to be similar to your situation.

There are some situations in which that occurs, but it seems very unlikely in your case. Let us assume that is not the case, until/unless evidence shows otherwise.

Assuming the disk size is OK, your issue is with the partition size. So you might want to expand the partition to fill the disk.

But that requires booting from some other media, which usually requires being there, which you say you are not. So skip the idea of expanding the partition.

So you don't need to expand the partition. Instead you can create another partition, and use lvm to use that space for more room in /

So you need to find out what non GUI partitioning tool (parted of fdisk, etc.) is available (typically in /sbin). Or if there is a non GUI partitioning tool you prefer to use and it isn't there, I assume you know how to use the non GUI package management tool.

Get a partition list from that tool. Post it here, if you aren't experienced with such things. With fdisk that command (as root) is
/sbin/fdisk -l

Then that same non GUI partitioning tool has commands to create the desired new partition.
(See man pages for that tool).
Then lvm can be told to use that space (see man pages. I have no clue about lvm).

SIGH

dd is the wrong tool for these kind of operations. It is a tool to make images. If you image a 10 GB disk, you get a 10 GB disk. Don't complain about it.

The steps to transfer the OS to a larger disk:
- Partition the new disk as you wish
- Mount the new disk in the directory tree of the old disk
- use rsync or tar to copy all the files from the old partitions to the new partitions with the proper parameters to preserve ownership and permissions
- Get the UUID of the new partitions, adjust /etc/fstab and grub.conf or menu.lst accordingly
- chroot into the root of the new disk and install grub

This is all done using standard tools. More sophisticated tools exist.

There are a gazillion manuals on how to do this in detail on Google. Therefor I only gave a coarse outline.
