You have to rearrange the unallocated space at the end of the LVM. So I thought I could run pvresize -setphysicalvolumesize /dev/sda5 /dev/sda5: cannot resize to xxxxx extents as later ones are allocated. Now I need to shrink the Physical Partition down so I can create a new Physical partition with the space to install Windows 8. Which successfully shrunk the logical partition. So, after some extended chat I came down to this command sudo lvresize -verbose -resizefs -L -150G /dev/ubuntu/root I am asking here if this is the correct thing to do before I bust my system. This prevents me from doing anything, I can select the partition, and there is an option for "deactivate" which If I am correct I believe is deactivating swap? If I do that I can manipulate the partition. ![]() So, the Ubuntu partition has a lock icon next to it. The issue is that I cannot work out how to shrink the partition, normally it's fine from the Gparted (gparted-live-0.14.1-6-i486.iso) live iso, Simply resize and you are good to go.īut this time Ubuntu has been installed with LVM. I wish to resize this to 450GB, so I can install Windows 8 as a dual boot. I told Ubuntu to overwrite everything as I was in a hurry, hence I only have the two partitions Ubuntu creates, the Boot Partition of a couple a hundred MB, and then everything else. Please do share your feedback and queries in below comments section.I have installed Ubuntu 12.10 as the only OS on my system. That’s all from this post, I hope you have found it informative and insightful. $ echo '/dev/vg01/lv01 /data ext4 defaults 0 0' | sudo tee -a /etc/fstab For permanent mounting append following entry in /etc/fstab file. ![]() Great, above output confirms that LVM partition is mounted on /data directory. Verify the mount using following df command $ sudo df -Th /dataįilesystem Type Size Used Avail Use% Mounted on To access this file system, create a mount point using mkdir command and mount it. $ sudo mkfs.ext4 $ sudo mkfs.ext4 /dev/vg01/lv01Ībove output shows that lvm has been formatted with ext4 filesystem successfully. In this demonstration, I am formatting the lvm partition with ‘ ext4’ file system. To format LVM partition, we can use mkfs command. So, to start using this lvm partition, first we must format it. Perfect, above output shows that lv has been created successfully. Verify the logical volume status by running following commands, Rounding up size to full physical extent 9.99 GiB In our case, I would be creating a lv of size 10 GB with name ‘lv01’. To create a logical volume (lv) from volume group (vg), use following command Step 3) Create Logical volume (LV) from Volume Group (VG) Verify the volume group status using following commands, $ sudo vgscanĪbove output confirm that volume group vg01 has been created successfully and size of each physical extent is 4 MB (this is the default size). So, in our case, command would be $ sudo vgcreate vg01 /dev/sdb Run beneath command to create volume group, $ sudo pvscanĬreating volume group (vg) means adding physical volume (pv) to vg. Verify the PV status using following commands. Note: In case pvcreate command is not available in Ubuntu system then install lvm2 package using following apt command. Physical volume "/dev/sdb" successfully created. $ sudo pvcreate … $ sudo pvcreate /dev/sdb So, let’s create physical volume (pv) using following command. As we can clearly see that we have a disk of 10 GB (/dev/sdb) which have no partition and available as raw disk. ![]()
