This article describes how to configure a new partition from free space on a dedicated server, or a virtual machine with full virtualization (such as VMware or XenServer):
- Verify the partitions available on the server: fdisk -l
- Choose which device you wish to use (such as /dev/sda or /dev/sdb)
- Run fdisk /dev/sdX (where X is the device you would like to add the partition to)
- Type ‘n’ to create a new partition.
- Specify where you would like the partition to end and start. You can set the number of MB of the partition instead of the end cylinder. For example: +1000M
- Type ‘p’ to view the partition, and type ‘w’ to save the partition
- Run the command ‘partprobe’ to have the OS detect the new partition table. If it still does not detect the partition table, you might need a reboot.
- Format the partition by doing: ‘mke2fs -j /dev/sdaX’ – where X is the number of the partition you have created.
- Create a directory where you wish to mount the new drive, for example: /newpartition. ‘mkdir -p /newpartition’
- To mount, you can use the following command: ‘mount /dev/sdaX /newpartition’
- If you would like the drive to be mounted automatically each time you boot, add the following to /etc/fstab: ‘/dev/sdaX /newpartition ext3 defaults 1 2’
Make sure you have backups before you perform any formatting, or creating new partitions!
