What command do you use to create Linux file systems?

case1:

fdisk -- to create a partition from hdisk

mkfs -t filesystem  to format the partion you want

case2:

fdisk -- to build a partition and make it as LVM sign

pvcreate -- to create a PV

vgcreate -- to build a VG and add PVs into VG

lvcreate -- to build a LV

mkfs -t format -- to format the filesystem into that LV

mkfs command

Example:

mkfs -t ext3 /dev/hda1

There are also type specific command, which in fact are called by mkfs; these are:

mke2fs mkfs.ext3 mkfs.msdos mkfs.vfat

use:

man mke2fs man mkfs.ext3 man mkfs.msdos man mkfs.vfat

for the type specific options available. Note: mke2fs and mkfs.ext3 are usually the same file.

mkfs -t <filesystem option> <device name>

Filesystem options = vfat, ext2, ext3,ext4 etc.

Device Name= raw disk, basic partition, Logical Volume  such as /dev/hda1, /vg00/lv0 etc. 

I agree with Mr Steven Liang
