Suppose you are required to create a 10 GB partition on your server running Linux, you have got two options namely :
- Create a partition from the unpartitioned space on your machine or
- Add a new drive.
If you are opting for the latter then it is a simple thing of plugging in the new drive, letting the system detect it, using a partitioning tool to create the requisite partition, formating the newly created partition and finally mounting it. But if it is the former namely, creating a partition from unpartitioned space, then the task gets a bit trickier.
Joey Prestia explains the exact steps needed to add a new partition to an existing system. The task can be broken down into the following steps :
- Determine what partitions need to be created and where.
- Create the partitions (I use 'fdisk' here but any Linux disk partitioning tool should work)
- Re-read the partition table either with 'partprobe' or by a reboot
- Make a filesystem on the partition, label it, and create the necessary mount points
- Add the appropriate entries to '/etc/fstab' so the partitions are mounted upon reboot
Check out Joey's notes to know the exact commands used to accomplish the above tasks.
