Inside vmware ESXI I have a CentOS virtual machine, and I resized the virtual disk from around 30 GB to 120 GB using vmware "edit" vm menu.

Then I booted using a gparted bootable ISO and resized the partition from 30GB to maximum (120 GB)

But now when I boot I still see the main partition (/root) as around 25 GB. From what I can tell (below code) the disk is seen as ~120GB but not the partitions ?

What commands to run in order to safely expand the partition ? I think that is /root that needs to be expanded.

[root@localhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/centos-root 26G 1.6G 25G 6% / devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 0 3.9G 0% /dev/shm tmpfs 3.9G 8.9M 3.9G 1% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sda1 1014M 145M 870M 15% /boot tmpfs 783M 0 783M 0% /run/user/0 [root@localhost ~]# fdisk -l Disk /dev/sda: 128.8 GB, 128849018880 bytes, 251658240 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x000d5212 Device Boot Start End Blocks Id System /dev/sda1 * 2048 2099199 1048576 83 Linux /dev/sda2 2099200 251658239 124779520 8e Linux LVM Disk /dev/mapper/centos-root: 27.9 GB, 27913093120 bytes, 54517760 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mapper/centos-swap: 3221 MB, 3221225472 bytes, 6291456 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes

    You have a logical volumes which you need to extend. Add the output of lsblk -f as well as pvs and vgdisplay and lvdisplay to your question. Commented Apr 16, 2019 at 23:31
  • I added lsblk -f and pvs Commented Apr 16, 2019 at 23:35
  • Also add vgdisplay and lvdisplay. Do you want to extend to all of the free space that you added? Commented Apr 16, 2019 at 23:36
  • Added vgdisplay and lvdisplay. Yes, I want to expand to that full space (~120 GB) Commented Apr 16, 2019 at 23:38

Edit:

It looks like you've already created the partition and physical volume and added the space to the volume group so I've removed the parts regarding adding a new partition to the disk and creating a new physical volume.

To expand your root logical volume:

lvextend -l +100%FREE /dev/centos/root

To sync the new space:

xfs_growfs /dev/centos/root

Run df -h to see the new size with the extra space and lvdisplay | sed -n '/root/,$p to see the increased size of the root logical volume itself.

  • Thanks. The commands need to be run from a different ISO ? Or I can run them from the partition's OS ? Commented Apr 17, 2019 at 9:52
  • @adrianTNT Run them from inside of the OS itself. Commented Apr 17, 2019 at 12:06
  • Great. It worked nicely. Commented Apr 17, 2019 at 13:43
