I have this article http://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-disk-storage-parted-resize-part.html which is not clear to me.
And also someone told me that swap space does not need to be disable if it is before the partition to resize.
Modifications: This is the related question extend size of partition. I am resizing a partition to add the extra/unallocated 1500GB disk space on the same disk. And would be better not to do it with lvm if possible.
I hope someone would enlighten me. Thanks
