As explained previously there is a risk of the journal becoming corrupted possibly causing file system corruption.
如上所述，不一致的事务日志有可能导致文件系统的崩溃。
If an operating system bug, bad disk sector, or even certain superuser errors cause corruption to a file system, using multiple volumes can limit that damage to just one volume.
如果操作系统缺陷、磁盘坏扇区或某些超级用户失误会破坏文件系统，使用多个卷可以把破坏的范围限制在一个卷。
Journaling file systems provide reliability and protect against corruption in the face of system crash or power loss.
日志文件系统在系统崩溃或断电时提供了可靠性，并防止系统崩溃。
To sum up, journaling file systems are fault-resilient file systems that use a journal to log changes before they're committed to the file system to avoid metadata corruption (see Figure 1).
总之，日志文件系统就是一种具有故障恢复能力的文件系统，它利用日志来记录尚未提交到文件系统的修改，以防止元数据破坏(请参见图1)。
All files here are vital, and the corruption or removal (whether intentional or accidental) of even one file can render a system useless.
其中所有的文件都是至关重要的，损坏或者删除(无论是有意的还是无意的)某个文件就可能使系统变得无法使用。
You may not have wanted to get so in-depth with your file system but the techniques covered here are pretty important to understand particularly because there is a risk of data corruption.
你可能并不想深入文件系统的底层了解这些东西，但本文介绍的技术对于你理解文件系统的使用异常重要，因为存在数据丢失的风险。
For example, one file system may be optimized for speed, another for efficient use of space, and yet another for durability against data loss or corruption.
例如，一种文件系统可能是以提高速度为目的而优化的，另一种文件系统偏重高效地使用空间，还有一种文件系统偏重于防止数据丢失或损坏。
Your problem could be caused by corruption at the file system level, and CHKDSK may be able to fix the problem.
你的问题有可能是文件系统级的损坏引起的，CHKDSL可能可以修复这一问题。
If multiple computers are allowed to write to the same file system without knowledge of what the other nodes are doing, it will quickly lead to data corruption and other serious problems.
如果多个电脑都允许写相同的文件系统，但是又不知道其它的节点也在瞎搞，很快就会出现数据崩溃和其它的严重问题。
