Hi,

I extended spaces (20GB) on my VM (Linux), and I also have used GPARTED to resize it, However, there are something wrong or something that I need to do and I missed it.

If you see the screenshots, you will be able to see some differences: the name of devices as /dev/sda1 and 2, but on Linux, the names are /dev/hda1 and 2. On gparted I am able to see the 20GB added to the sda2, but I am not able to see on Linux.

See below other information such as df command, and pv and lv.

So, if someone could help me how to add the space (on root directory) with no losing the data, I would appreciate a lot.

tks.

From what I can understand you have Linux guest VM running in VMware. You turned off the VM and increased the size of the existing disk by 20 GB. Turned the VM on after that you are able to see increased space in fdisk -l but your logical volume still shows the old size.

Do you have the backup of the existing system. It is always advisable to have good / verified backup of existing data before playing around with partitions.

Would like to know if you have tried running:

Hi T3RM1NVT0R,

thank you for the information.

Yes, the increase was done with VM off, and then I started it. I had 80GB before, and I added 20GB, as you see.

When I executed the command that you wrote, I receive a message that the vol is mounted.

If you see the information, the mounted directory is the root (/).

Any other way to execute it or to make it available the 20GB on root directory?

tks.

Sorry I missed that, for that you have to boot the system in rescue mode and from there you need to run resize2fs.

Hi, I have been trying to boot as rescue mode, but there is something wrong. First of all, the first installation ins Centos 4.9, and I have upgraded to 5.3. None of these operating system are supported and available. So, I have been using the last version (Centos 7). However, when I boot via DVD, the first screen is arisen, but there is no option to rescue mode. If I try to choose Install Centos 7, or other options, it seems that the system hangs and nothing happens.
So, is there other way to resize the root directory, considering that it is the solution to get the additional space extended?
tks.

You have to type in Linux rescue at the boot prompt when you boot using DVD. Try the following link: https://www.centos.org/docs/5/html/I...mode-boot.html

Edit: Just tested, you can hit escape key and it will drop you to boot: there you type Linux rescue to boot in rescue mode. In earlier version like RHEL5 you get to type upfront without hitting the escape key.

Hi,

I had to download the DVD #1 in order to be able to get the screen with - Rescue Mode option.

After this, I also had to follow some options, and then I was able to write the command: linux rescue.

Once that, it worked, the root directory was resized with the GB added.

I thought that it should work only using GPARTED on boot process, but, anyway....it worked now.

thank you.

You're welcome. Good to hear that it has been fixed.

Please mark the thread as solved.

Enjoy Linux!!!
