8.1 Adding space Virtualization provides a number of ways of adding space that can be used by a Linux partition and the method depends on a number of factors including availability of the server, as well as the structure of the Linux disk partitions. This section will document two methods, increasing the size of an existing virtual storage space and creating a new storage space for the partition. 8.2 Increasing size of storage space This method for adding additional space to the Linux partition can be used when the Linux file system to be resized is the last file system on the disk (storage space). As an example, imagine that the disk partitions on the storage are configured as shown in Figure 8-1: P re p B o o t Figure 8-1 Linux Disk Structure Note: This structure is the default structure for a Novell / SuSE SLES 9 and SLES10 installation. This structure is not the default structure for RedHat RHEL 4. Within Linux, the above disk structure is represented by the following devices:
