18.3 "Linux learning is not difficult" file system management ( 3 ): create a file system in the Linux system
Various file systems can be created on a partition using the mkfs command. The mkfs command itself does not perform the work of establishing a file system, but calls the relevant program to execute it. The file system here is to be specified, such as xfs , ext4 , ext3 , vfat or msdos .
Command syntax:
mkfs [ options ] [ device ]
The meaning of each option in the command is shown in the table.

Meaning of options |
-t < filesystem type > |

-v |

Example: Create an xfs file system for the /dev/sda5 disk partition .
[root@rhel ~]# mkfs -t xfs /dev/sda5 meta-data=/dev/sda5 isize=256 agcount=4, agsize=6553600 blks = sectsz=512 attr=2, projid32bit=1 = crc = 0 finobt = 0 data = bsize=4096 blocks=26214400, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=0 log =internal log bsize=4096 blocks=12800, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0
Of course, the disk partition can also be formatted into other file system types. For example, /dev/sda5 can be formatted as ext4 , ext3 , or vfat file system type.
Example: Format the /dev/sda5 partition and create an ext4 file system.
[root@rhel ~]# mkfs -t ext4 /dev/sda5
Example: Format the /dev/sda5 partition and create an ext3 file system.
[root@rhel ~]# mkfs -t ext3 /dev/sda5
Example : Format the /dev/sda5 partition and create a vfat file system.
[root@rhel ~]# mkfs -t vfat /dev/sda5
Note :
You can also use the commands mkfs.xfs , mkfs.ext4 , mkfs.ext3 , mkfs.ext2 , mkfs.msdos , mkfs.vfat etc. to create different file systems on disk partitions.
