请问:
1.为什么日志式文件系统可以有更高的硬盘空间使用效率(如Ext3比Ext2)
2.使资料在各种不同的档案大小中能够快速的读取及写入。
出自:鸟哥的Linux私房菜

个人怎么觉得:
对于问题1:ext2不用写日志,空间利用更好啊
对于问题2:
莫非是
(1) 你读取文件a
(2) 日志记录文件a的具体位置
(3) 你再次读取a
(4) 可以从日志中直接得到具体位置,即磁头直接到达.不用去找什么inode,block

最后,谢谢各位的回答.

Windows读写Ext2/Ext3/Ext4文件系统

可以读写Ext2,以Ext2方式挂载Ext3文件系统(不支持Ext3日志),不支持中文! It provides Windows NT4.0/2000/XP/2003/Vista/2008 with full access to Linux Ext2 volumes (read access andwrite access). This may be useful if you have installed both Windows and Linux as a dual boot environment on your computer. What features are supported? Complete reading and writing access to files and directories of volumes with theExt2 orExt3 file system. Supports features which are specific to the I/O-system of Windows: Byte Range Locks, Directory Notfication (so the Explorer updates the view of a directory on changes within that directory), Oplocks (so SMB clients are able to cache the content of files). Allows Windows to run with paging files on Ext2 volumes. UTF-8 encoded file names are supported. The driver treats files with file names that start with a dot "." character ashidden. Supports GPT disks if the Windows version used also does. Supports use of the Windows mountvol utility to create or delete drive letters for Ext2 volumes (except on Windows NT 4.0). See also section"Can drive letters also be configured from scripts?". What features are *not* supported? Inodes that are larger than 128 bytes are not supported. Access rights are not maintained. All users can access all the directories and files of an Ext2 volume. If a new file or directory is created, it inherits all the permissions, the GID and the UID from the directory where it has been created. There is one exception to this rule: a file (but not a directory) the driver has created always has cleared "x" permissions, it inherits the "r" and the "w" permissions only. See also section"What limitations arise from not maintaining access rights?". The driver does not allow accessing special files at Ext2 volumes, the access will be always denied. (Special files are sockets, soft links, block devices, character devices and pipes.) Alternate 8.3-DOS names are not supported (just because there is no place to store them in an Ext2 file system). This can prevent legacy DOS applications, executed by the NTVDM of Windows, from accessing some files or directories. Currently the driver does not implement defragging support. So defragmentation applications will neither show fragmentation information nor defragment any Ext2 volume. This software does not achieve booting a Windows operating system from an Ext2 volume. LVM volumes are not supported, so it is not possible to access them.
