Partitioning the hard drive is essential part of Linux usage. Fdisk is a tool you can use for this purpose. Here we bring you a howto on fdisk for Linux, which mind you, is separate from the fdisk for Windows that most of us are familiar with. This is a matter of confusion for most rookies. For apart from sharing a name, there’s a world of difference between the two.
Running out of disk space on partitions is a problem commonly and universally experienced by all of us. And although there are various solutions, almost all of them are temporary. In this article we take a detailed look at LVM, which tackles the problem in the most effective manner, making space management easy.
