5.3 Formatting the Unallocated Disk Partition

In order to make the new partition suitable for use by CentOS 8, it needs to have a file system created on it. The default file system type for the current release of CentOS is XFS and will be covered in greater detail in the chapter entitled “Adding a New Disk Drive to a CentOS 8 System”. Creation of the file system is performed using the mkfs.xfs command as follows:

# mkfs.xfs -f /dev/sda1

meta-data=/dev/sda1 isize=512 agcount=4, agsize=1676672 blks

         = sectsz=512 attr=2, projid32bit=1
