How to increase the disc space

smsuil · 11-14-2022, 02:44 AM

Hi all,

Ubuntu 22.04
Disc - 2TB PCIe Gen 3 x 4 NVMe SSD

It was restored on the backup image
Ubuntu 22.04
Disc - 1TB PCIe Gen 3 x4 NVMe SSD

$ lsblk -e 7 -o name,size,type,fstype,mountpoint

Code:

NAME                    SIZE TYPE FSTYPE      MOUNTPOINT
sda                     3.6T disk             
└─sda1                  3.6T part ext4        
sdb                   931.5G disk

└─sdc2                465.3G part ext4        
nvme0n1                 1.8T disk             
├─nvme0n1p1             512M part vfat        /boot/efi
└─nvme0n1p2           953.4G part LVM2_member 
  ├─ubuntu--vg-root   930.4G lvm  ext4        /
  └─ubuntu--vg-swap_1   976M lvm  swap        [SWAP]

The disc is now running short of space. Actually it has 1TB un-allotted to ubuntu--vg-root.

Please advise how can I use the un-alloted 1TB space?

Thanks in advance.

Regards

Let's see these.

Code:

df -hT
pvs
vgs
lvs

You should be able to exclude those snaps from the df as well ...

Hi syg00,

Further to my previous posting;

$ lsblk -o "NAME,MAJ:MIN,RM,SIZE,FSTYPE,MOUNTPOINT,UUID" | grep ubuntu

Code:

  ├─ubuntu--vg-root   253:0    0 930.4G ext4        /                                ef229efa-3019-4ba9-bddc-88c399244e99
  └─ubuntu--vg-swap_1 253:1    0   976M swap        [SWAP]                           ae829a93-d744-47b2-b378-85d58950c720

$ lsblk -o "NAME,MAJ:MIN,RM,SIZE,FSTYPE,MOUNTPOINT,UUID" | grep nvme0n1

Code:

nvme0n1               259:0    0   1.8T                                              
├─nvme0n1p1           259:1    0   512M vfat        /boot/efi                        0E3A-4ABA
└─nvme0n1p2           259:2    0 953.4G LVM2_member                                  WmiqMV-mxBN-xNbz-WKk3-04Qm-OEvb-gfo2C6

compare the screenshot "Computer/dev/disk/by-uuid (attached here)

ubuntu--vg-root -> ef229efa-3019-4ba9-bddc-88c399244e99 is there

nvme0n1p2 -> WmiqMV-mxBN-xNbz-WKk3-04Qm-OEvb-gfo2C6 is NOT there. Not mount yet?

I think this will work.
Boot from the other installed ubuntu or from live usb.
use gparted to fix drive size and resize /dev/nvme0n1p2

Code:

sudo pvresize /dev/nvme0n1p2
sudo lvresize -l +100%FREE /dev/mapper/ubuntu--vg-root
sudo e2fsck -f /dev/mapper/ubuntu--vg-root
sudo resize2fs /dev/mapper/ubuntu--vg-root
