How to view the Linux file system block size implementation _linux

On Linux systems, you can use command TUNE2FS to test the following

[Root@localhost test10g]# tune2fs-help tune2fs 1.35 (28-feb-2004) tune2fs:invalid option--H usage:tune2fs [-C Max-mo Unts-count] [e-errors-behavior] [G Group] [-I interval[d|m|w]] [-j] [-j journal-options] [-l] [-s sparse-flag] [ -M reserved-blocks-percent] [-O [^]mount-options[,...]]
    [R Reserved-blocks-count] [-u user] [-C Mount-count] [-L Volume-label]

The block size above is the blocks.

On a Windows system, you can use the command fsutil to view the following tests:

C:\Documents and Settings\ct2>fsutil--help
--HELP is an invalid parameter.

The number of cluster bytes above is both block size.

Note: The second extended file system (second Extended filesystem,ext2). EXT3 (third Extended filesystem)

Man FS ext2 are the high  performance disk filesystem used by Linux for fixed disks as as a  removable Media.  The second extended filesystem is designed as an extension of the
       extended file
       System (EXT).  EXT2 offers the best performance (in terms of speed and CPU usage) of the filesystems supported under
       Linux.
    Ext3 is  a journaling version of the ext2 filesystem. It is easy to
       switch back and forth between ext2 and ext3.
    Ext3 is  a journaling version of the ext2 filesystem Ext3 offers the most
       complete set of journaling />available  among
       journaling filesystems.

The above is small series for everyone to see the Linux file system block size of the implementation of the whole content, I hope that we support cloud Habitat Community ~
