This is an advantage of Linux, especially as a server, this is more useful. In contrast, Microsoft's DOS and Windows can only be installed in primary partition C. What are the advantages of Single-partition and multi-partition installation? A single partition is easier for beginners. As long as one

Linux requires that each hard disk device can contain a maximum of four primary partitions (including extended partitions). Any extended partition occupies a primary partition number, that is, a hard disk, the maximum number of primary and extended partitions is four. For earlier DOS and Windows (versions earlier than Windows 2000), the system recognizes only one

Use LVM on Ubuntu to easily adjust partitions and create snapshots The Ubuntu installer provides a check box to easily "use LVM. In its description, enabling logical volume management allows you to create snapshots and easily adjust the size of Hard Disk Partitions-here we will show you how to complete these operations. LVM is a technology that is similar to RAID arrays or "buckets" on Windows. Although th
