Answer: Mkfs-t vfat/dev/hdc6

[ [email protected] ~]# mke2fs [-BICLJ] Appliance Name
Parameters:
-B: You can set the size of each block, currently supports 2048, 4096 bytes three kinds;
-I: How much capacity is given to an inode?
-C: Check disk errors, only once-C, will be a quick read test;
If you release two times-c-c, will test read and write (Read-write), will be very slow ~

[[email  protected] ~]#  mke2fs [-BICLJ] Appliance name
parameter:
-B&NBSP: You can set the size of each block, currently supports the 2048, 4096 bytes Three kinds,
-i : How much capacity is given to an inode?
-c : Check for disk errors, only once-C, will be a quick read test;
      If you release two times-c-c, it will test read and write (Read-write), it will be slow ~
-l : Can be followed by the table header name (label), this label is useful Oh! Later will say ~
-j : Originally MKE2FS is EXT2, plus-j, will actively join Journal and become EXT3.

This filesystem would be automatically checked every mounts or
Whichever comes first. Use Tune2fs-c or-i to override.
# This way we can build a system for him. Cotton ~

Example two: If the block is changed to 2048, and the inode is changed to 4096?
[[email protected] ~]# mke2fs-j-L "logical"-B 2048-i 4096/DEV/HDB5
# The results are roughly similar to the example one ~ but the block size and inode count will change!
The above is the command function of MKE2FS, that is, MKE2FS default is formatted as EXT2 format, if the -j parameter is ext3 format, can only format the two formats;

And for MKFS is not only the format of ext2 and ext3 two formats, it can be formatted as other file system formats, MKFS is a set of many functions integrated command, you can refer to ll/sbin/mkfs* View System can support the file system format,

You can also view Help for man Mkfs. Such as: formatted as EXT3--->># mkfs.ext3/dev/hdb2
