I use a CentOS virtual machine on VMWare Workstation. I recently tried to increase the system hard disk memory for CentOS by tweaking the VM settings on VMWare Workstation. After that, I tried to follow the steps as listed here: http://kb.vmware.com/selfservice/search.do?cmd=displayKC&docType=kc&docTypeID=DT_KB_1_1&externalId=1006371
However, when I try to list the Volume Groups using vgdisplay, it shows that there are no Volume Groups. How do I resolve this issue?
terminal on typing vgdisplay:
Incorrect metadata area header checksum on /dev/sda4 at offset 4096
No volume groups found
The new partition to be added is /dev/sda4
terminal on typing fdisk -l :
Disk /dev/sda: 128.8 GB, 128849018880 bytes
255 heads, 63 sectors/track, 15665 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes

Partition 1 does not end on cylinder boundary.

/dev/sda4 2611 15665 104857592+ 8e Linux LVM
I cannot figure out where I am going wrong. Please help.
