Disk management in operating system how to#

These partitions are now called primary partitions.Дў. Primary Partitions - The number of partitions was limited from the very beginning and we can have only four partitions. This is all we have to know to deal with linux disk devices file.ДЎ. dev/hdb2 - Second partition of second drive. dev/hdb1 - First partition of second drive. dev/hda2 - Second partition of first drive. dev/hda1 - First partition of first drive. Once a drive has been partitioned, the partitions will be represented as numbers on the end of the names.ДЇor example, lets assume that we have two IDE Drives with partitions as below. dev/sdb - 'b' refers, its a second drive. dev/sda - 'a' refers, its a first drive. SCSI drives follow a similar pattern They are represented by 'sd' instead of 'hd'. SCSI Drives device names would be /dev/sda, /dev/sdb. dev/hdd - 'd' refers, its a fourth drive.Дў. dev/hdc - 'c' refers, its a third drive. dev/hdb - 'b' refers, its a second drive. dev/hda - 'a' refers, its a first drive. IDE drives device names would be /dev/hda, /dev/hdb. Linux maintains the naming conventions for IDE drives and SCSI Disks.ДЎ. In Linux, all disks are represented as block devices only. Have a look on the first integer of two lines from the output, those starts with 'b' for first two line which are block devices (hda and sda). In Linux, partitions are represented by device files.

Later on there may be a need to create new partition for these directories or for other mount points, So admins should be able to create a new partition manually using partition editors. so all other directories of linux like /usr, /var, /bin will be created under this /(root).

Many new Linux admins create only two partitions / (root) and swap for entire hard drive. Once a disk is divided into several partitions, directories and files of different categories may be stored in different partitions.

In the next article, We explained you How to Create and Delete Partitions using fdisk in Linux.Дisk partitioning means, divide a single hard drive into many logical drives using partition editors such as fdisk, parted tools. Lets discuss about the partitioning, naming conventions, partition types, primary partitions, extended partitions, logical partitions, file systems. This article explains you the Disk management in Linux to understand the basic disk management concepts.
