Copying root partition and /home to a new larger hard drive

view story
linux-howto

http://askubuntu.com – I am getting a larger hard drive and would like to copy root directory to it. The partition for root is 20G. I would like to make it larger on the new drive. I also would like to copy /home to a larger partition on the new drive. Could I use dd to copy the partition or is there a better way to copy the partition? Should I format the new drive before copying the partition? What else will I need to do beside sudo update-grub to show I will be using the new drive? I know it subjective but I've found 20G a little low for a root partition if you add a lot of programs. Would 40G be large enoug (HowTos)

Stories similar to Copying root partition and /home to a new larger hard drive

I'm not sure how to explain this in the subject better, so the "question" may not be right. But here goes. I have three hard drives. Drive A is a 320GB drive, Drive B is a 80 GB Drive, and Drive C is a 1TB Drive.

to everybody. right now i am writing this to you on a trial download version of ubuntu 10.04.4LTS on a pc that i built and i want to know how i can put a root partition along side of my copy of windows xp professional on the same hard drive on different places such as c:/ and x:/ as the root partition because I want to be able to duel boot them, but i do not have the disk to partition the hard dri

Dear all,

I have a large external drive, which I connect to my laptop via a PCMCIA card - the machine is old and does not have USB 2.0 built in, so I use the PCMCIA card for that.

I am thinking of the following setup, and hope you can give me some tips on whether or not that would be a sound solution:

We have recently upgraded a system HDD - it was 160GB, now 2TB. We upgraded as we were running low on space, mainly on /usr, and also on /home.

I prepared the new drive with a Live CD and GParted (and made some partitions larger). Then I cloned /, /usr, and /boot to the new drive using dd. The partition size of /usr on the old drive was 23GB, but I made it ~50GB on the new larger drive.

Recovering Installation 16 weeks 3 days ago

I was installing a copy of Windows Xp on a second drive on my computer and accidentally deleted the partition on my second hard drive that contained my copy of Fedora 14 ( I accidentally selected the second drive while selecting a partition to install Windows and deleted the partition - but I didn't format it or anything ). The computer will not boot from my Linux drive now.

I can see that my root partition is down to single-digit GB free out of 134GB root partition on a larger server with many SAN, NFS, LOFS mounts etc mounted at the root (/) partition.

How can I specifically tell which directories is causing the most utilization in my root (/) partition?

details: 1 TB HDD with one partition using full drive. Only 39 GB used of the partition.

120 GB SSD unformated, unpartitioned

I've used clonezilla to save a clone of the 1 TB HDD. I'd like to restore the image to the 120 GB SSD.

Is this possible? I was thinking that since only 39GB is used on the partition it should be able to be restored to my SSD.

[other] Partition help 21 weeks 5 days ago

I don't know if this is the right forum, but I will ask anyway. I made a seperate partition from my C: drive that was 15 gb for ubuntu and kept my C drive for windows, thinking I could just use that while in linux to play my games.

I'm experiencing the all-too-common "root partition full" situation. 100% of my hard drive is allocated. My home partition has plenty of space to give up.

Is there an amazing step by step tutorial out there for this type of a scenario where the root partition needs to be expanded?
