Partitioning the devices After the device parameters have been set, the next step is to set the partitions. To partition the devices: 1. Enter fdisk/dev/device_name. Example # fdisk/dev/sda 2. Select p to display the present partitions. 3. Select n to make a new partition. You can make up to four primary partitions or you can make one extended partition. The extended partition can be divided into a maximum of 11 logical partitions, which can be assigned partition numbers from 5 to 15. 4. Select w to write the partition information to disk and complete the fdisk command. 5. Other commands that you might want to use include: d to remove partitions q to stop a change 6. Repeat the above steps for each device. Creating the file systems The supported file system for Linux is ext2. Creating file systems with ext2 1. Enter mkfs -t ext2 /dev/device_name.
