Topic: resize successful but OS disk size the same

Using centos 6.5 64bit on VMware. I increased the disk size, then used gparted live cd to resize partition from 10G to 20G. The resize was successful and I did a reboot. However the OS still reports the original 10G size. Is there a step Im missing ?

You can try to run "check" on that partition within GParted.
Please, look at the GParted Manual for details.
The chapter title is "Checking a Partition".

*** It is highly recommended to backup any important files before doing resize/move operations. ***

Thanks
I did run 'check', and there are no errors. I have included some screenshots of the gparted screens and the last one is my OS showing still the unchanged partition size.

Re: resize successful but OS disk size the same

From the screen shot in post #3 it appears that the Logical Volume Manager 2 Physical Volume in partition /dev/sda2 uses the majority of the disk drive.

It looks like your OS is most likely installed on an LVM2 Logical Volume within the LVM2 PV.

To grow or shrink LVM2 LVs within the LVM2 PV, then additionally you will need to investigate resizing the LVM2 LVs.  For example the terminal command to resize an LVM2 LV is lvresize.
