Hi ALL, I have a harddisk with 3 primary partitions and one extended partitions. Under extented partions , there are 15 partions. Whole hard disk has been partitioned in a standard way, (i.e NOT LVM) It has 2GB ram. swap is also 2GB. Now I want to extend this swap to 4 GB. If I use dd coomand and create a file with 2GB, Will I be able to extend the swap witn swapon commnad? How can I achive this? Hope to hear form you, -- Thank you Indunil Jayasooriya
