With ReiserFS, XFS, and JFS, the filesystem driver journals metadata, but makes no provisions for journaling data. 使用ReiserFS、XFS和JFS时,文件系统驱动程序记录元数据,但不提供数据日志记录。
In ext3, the journaling code uses a special API called the Journaling Block Device layer, or JBD. 在ext3里,日志记录代码使用一个特殊的称为“日志记录块设备”层或JBD的API。
Linux also supports the new journaling file systems such as ext3, JFS, and ReiserFS. Linux还支持ext3、JFS和ReiserFS等新的日志型文件系统。
The default method for journaling is ordered and supports online resizing to grow the file system. 其默认的日志记录方法为预定,且支持以在线调整大小的方式扩展文件系统。
Of course, XFS is a journaling filesystem, allowing for fast recovery after an unexpected reboot. 当然,XFS也是一种日志记录文件系统,它允许意外重新引导后的快速恢复。
In general, journaling file systems avoid file system corruption by maintaining a journal. 笼统地说,日志文件系统就是通过维护一份日志来防止文件系统崩溃。
Journaling file systems, while much more secure, historically have been associated with performance overheads. 日记记录的文件系统可以提供更高的安全性,但在以前,往往会带来性能方面的开销。
Journaled file system: Many file systems provide journaling to prevent loss of data. 日志文件系统:许多文件系统都提供日志以防止数据丢失。
If possible, you should use journaling file systems exclusively. 如果可能的话,应该只使用日志文件系统。
And ext3's journaling capabilities have been specially designed to ensure the integrity of both metadata and data. 还有,ext3的日志记录能力经过特别设计,以确保元数据和数据的完整性。
Like ext3, ext4 is a journaling file system. 和ext3一样,ext4也是一个日志文件系统。
The ext3 file system introduced the concept of journaling to improve the reliability of the file system when the system is abruptly halted. ext3文件系统引入了日志概念,以在系统突然停止时提高文件系统的可靠性。
Now that we have a good general understanding of this problem, let's look how ext3 implements journaling. 既然我们对这个问题已经有了一个总的很好的理解,让我们来看ext3是如何实现日志记录的。
Another four volumes were used in an LVM for mail journaling. 一个LVM中的另外4个卷用于邮件日志。
Newer journaling file systems simplify the disk-check process when the system starts up again. 比较新的日志文件系统简化了系统重新启动时的磁盘检查过程。
XFS uses the writeback journaling policy. XFS采用回写日志策略。
JFS2 supports ordered journaling for high performance with sub-second file system recovery. JFS2支持预定的日志记录方式,可以提高较高的性能,并实现亚秒级文件系统恢复。
Several years ago, Linux didn't even have a journaling filesystem. 几年以前,Linux甚至连一个日志记录文件系统也没有。
For this reason, data= ordered mode is a good higher-performance replacement for full data journaling. 出于这个原因,data=ordered方式是对完整数据日志记录的一个很好的更高性能的替代。
Journaling can help you document your recovery as you recover from depression. 当你从沮丧中恢复的时候,日记可以帮你记录你的恢复过程。
Start journaling your questions and your answers each day. 开始每天都记录下你的问题和答案。

The Optimization of Linux Journaling File System Linux日志型文件系统的研究及其性能优化
If any journaling mailbox rejects Journal reports, those journal reports are sent to the single alternate journaling mailbox. 如果任何日记邮箱拒绝了日记报告,这些日记报告将发送到单个备用日记邮箱。
Be sure to document through pictures and journaling those new traditions you and your fa-mily have created. 一定要通过照片和日志记录下你和家人创造的那些新传统。
There are important security and resource considerations when you configure the journaling mailbox that receives Journal reports. 在配置接收日记报告的日记邮箱时,需要考虑到一些重要的安全和资源问题。
Spend time journaling, meditating or contemplating over ideas you have learned. 多花点时间写日记,把你对这些学到的知识的思考和想法记录下来。
If you configure an alternate journaling mailbox, you can reduce the load on your Hub Transport servers and mailbox servers. 如果配置了备用日记邮箱,则可以降低集线器传输服务器和邮箱服务器的负载。
This helps reduce the possibility of tampering with journal reports that are delivered to the journaling mailbox. 这样有助于降低篡改传递到日记邮箱的日记报告的可能性。
Continue journaling for several months so you can see the changes in yourself and your life. 保持写日记几个月,你就会看到你自己和生活上的变化。
