How to resize a LVM partition?

http://askubuntu.com – I want to shrink my second (lvm) partition, so I can create a new partition in the freespace. I am using Live-CD to do so, because I know I can't resize/move this partition while it is in use. When I opened GParted in Live-CD, I realized that I could not resize the partition, because when I right-click it, the option "resize/move" is disabled. I tried to unmount it, to "lazy" unmount it (umount -l /dev/sda2) but it didn't work. A screenshot from GParted: (HowTos)

Hi All, I could really use some help here, I have made my /home partition inaccessible :( Problem started when I used gparted to resize and move /dev/sda3 (where all my personal data is). This partition is about 250G and the process was going to take some hours to complete so I went to bed before it finished.

Hello!

I have Ubuntu 13.04 installed on my (almost) my whole hard drive..and I would like to resize the main partition so I could install Windows 7 as well

The problem is..when using GParted (haven't tried anything else) I can't resize it. I tried to swapoff the swap partition and I still couldn't resize it.

Here's a screenshot of my current partition:

Thank you!

I had installed Lubuntu on a PC with Windows XP and used dual boot for some time with no problems.

Since I had almost abandoned Windows (kept it for printing...) I decided to resize its ntfs partition and add the free space to my Ubuntu space.

Tried that with a gparted stick and a live cd but would not work due to an issue related to the ntfs partition: gparted signaled with a red exclamation po

Hello,

I have tried to resize (shrink) my NTFS partition so that I will be able to get more space for my ext4 Ubuntu's (12.04 64 bit) partition but after the partition has been resized I am unable to mount it.

I am in progress of resizing a LUKS encrypted partition that contains a single ext4 filesystem (no LVM or something). The cryptsetup FAQ recommends to remove the old partition and recreate it, but that sounds like wasting a lot time. Therefore I want to proceeed by manually, carefully resizing the partition.

So far, I think that I need to do:

Unmount the existing ext4 filesystem (e.g.

So I've gotten my dual boot between Windows 7 and Ubuntu, but I've found that I might have underestimated the amount of space I need on my Ubuntu partition.

Dual Boot / Partition Issue 3 years 12 weeks ago

Hey guys I am fairly new with this so bare with me.

I just recently built a new computer (1st build) and installed Suse 11.2 as a fresh install on a brand new 500 GB hard drive. Everything is up and running fine. I am wanting to make it a dual boot machine by adding XP, but when I go to use the partitioner it won't let me resize my partitions to make space for XP.

I tried to resize my data partition with gparted, from a ubuntu 12.04 live usb. I then accidentally closed my laptop screen, which caused ubuntu to hibernate. After I tried to get it back up, the screen kept black and the hdd indicator didn't blink. I then rebooted (again to my live usb). Gparted shows now that the partition is of the desired size, but it can't detect the filesystem.
