Hello Guys In this tutorial we are going to learn how to create partition in Redhat linux Server. we can use partition create commands on all type of Linux operating system. in this tutorial i have Rhel5 Linux based operating system.<\/p>\n
So let we start just click right and open terminal as a root. if you have ubuntu based linux system just need to login root user.<\/p>\n
below command are show Heard disk status on your linux operating\u00a0 system<\/strong><\/span>.<\/p>\n [root@localhost Desktop]# fdisk -l<\/strong><\/span><\/p>\n Disk \/dev\/sda: 21.6 GB, 21613379584 bytes<\/span> Device Boot Start End Blocks Id System<\/span> now we will select our heard disk which one we need to create partition. here my heard disk name is \/dev\/sda if you have number of heard disk\u00a0 you will see de\/sdb ,\/dev\/sdc ,\/dev\/sdd. After put fdisk with our heard disk name disk partition editor will be open then we can look all kind of help when we put m<\/strong> and press enter\u00a0\u00a0<\/span><\/p>\n [root@localhost Desktop]# fdisk \/dev\/sda\u00a0<\/span>\u00a0 \u00a0<\/strong><\/p>\n The number of cylinders for this disk is set to 2627.<\/span> Command (m for help): m<\/strong><\/span> Command (m for help): n<\/strong><\/span> Command (m for help): n<\/strong> Command (m for help): n<\/strong> Command (m for help): n<\/strong> Command (m for help): p<\/strong><\/p>\n Disk \/dev\/sda: 21.6 GB, 21613379584 bytes<\/span> Device Boot Start End Blocks Id System<\/span> Command (m for help): w (save for partition<\/strong> Calling ioctl() to re-read partition table.<\/span><\/p>\n WARNING: Re-reading the partition table failed with error 16: Device or resource busy.<\/span> Here we need to reboot our system. but Here we suppose\u00a0 we are work on real server then we can’t reboot server for this Service. because Many people are connected to server. so Linuc in we have Commands. we can reboot only Heard Disk partition table. Commands is Partprobe and heard disk name which one we was create partition .\u00a0<\/strong><\/span><\/p>\n [root@localhost Desktop]# partprobe \u00a0\/dev\/sda<\/strong><\/span><\/p>\n Then we Formate our partition and mount in any folder which have required .<\/span><\/strong><\/p>\n [root@localhost Desktop]# mkdir data<\/strong><\/span> [root@localhost Desktop]# mkfs.ext3 \u00a0\/dev\/sda6<\/strong><\/span><\/p>\n [root@localhost Desktop]# \u00a0mount \u00a0 \/dev\/sda7 \u00a0data<\/strong><\/span><\/p>\n Then we will go to fstab file. this file in have all mounted device information we are also write New partition description<\/strong><\/span><\/p>\n [root@localhost Desktop]# vim\u00a0<\/strong>\/etc\/fstab\u00a0<\/strong><\/p>\n if you have any problem in this method please comment here i will solve your problem<\/p>\n Thank\u00a0 you<\/p>\n Vishnu Sharma<\/p>\n","protected":false},"excerpt":{"rendered":"
