In contrast, ReiserFS' fsck is in its infancy, and fixing flaky metadata when it does show up can be a difficult and dangerous process.

相反，ReiserFS的fsck還很幼稚，當(dāng)脆弱的元數(shù)據(jù)真的出現(xiàn)時(shí)，對(duì)脆弱元數(shù)據(jù)的修復(fù)過(guò)程將是困難和危險(xiǎn)的。

So, now you know for whom journaling file systems were created, but how do they obviate the need for fsck?

那么現(xiàn)在您應(yīng)該清楚日志文件系統(tǒng)針對(duì)的是哪類人群了，但是他們是如何取締fsck的呢？

fsck's job is to ensure that the to-be-mounted filesystems' meta-data is in a usable state.

Rather than restoring the system or even rebuilding the operating system, you can use fsck to repair file systems or correct damaged inodes.

您可以使用fsck來(lái)修復(fù)文件系統(tǒng)或者修正受損的inode，而不是還原系統(tǒng)、或者甚至重新構(gòu)建操作系統(tǒng)。

man fsck and info fsck provide details, as do several of the Resources included at the end of this article.

manfsck和infofsck，以及本文最后的參考資料中都提供了詳細(xì)的資料。

And unlike the more traditional approach that fsck takes, this journal replaying process does not take longer on larger filesystems.

并且與fsck所采用的傳統(tǒng)方法不同，這個(gè)日志重放過(guò)程在大型的文件系統(tǒng)上并不需要花更多的時(shí)間。

這是文件系統(tǒng)一致性檢查程序fsck所做的事情之一。

fsck must be run on unmounted volumes, though it is rarely needed unless the file system was not cleanly unmounted.

fsck必須運(yùn)行于已缷載的卷上，雖然除非是在文件系統(tǒng)沒(méi)有缷載完全的時(shí)候，否則很少會(huì)用到它。

And the best strategy for fixing file system issues is the simplest: the file system check command (fsck).

修復(fù)文件系統(tǒng)問(wèn)題最好的策略也是最簡(jiǎn)單的：利用文件系統(tǒng)檢查命令（fsck）。

Ext4 marks unused groups of blocks within the inode table to allow the fsck process to skip them entirely to speed the check process.

ext4將未使用的塊組標(biāo)記到inode表中，并讓fsck進(jìn)程忽略它們以加快檢查速度。

Journalling filesystems solve this fsck problem by adding a new data structure, called a journal, to the mix.

日志文件系統(tǒng)通過(guò)增加一個(gè)叫做日志的新的數(shù)據(jù)結(jié)構(gòu)來(lái)解決這個(gè)fsck問(wèn)題。

So, what does fsck do with a journalling filesystem?

那么，fsck如何處理日志文件系統(tǒng)呢？

By using the fsck command, you can narrow the search for damaged inodes, as well.

通過(guò)使用fsck命令，您還可以縮小受損inode的搜索范圍。

If you're searching for a specific inode, you can use the -ii-NodeNumber switch with fsck.

如果您正在搜索一個(gè)特定的inode，那么可以使用帶-ii-NodeNumber開(kāi)關(guān)的fsck命令。

Problems arise from the fact that fsck must scan a filesystem's entire meta-data in order to ensure filesystem consistency.

問(wèn)題出自于這樣一個(gè)事實(shí)―fsck必須掃描文件系統(tǒng)全部的元數(shù)據(jù)，以確保文件系統(tǒng)的一致性。

Check the documentation for your file system-specific fsck helper program to learn about its options.

檢查特定文件系統(tǒng)的幫助程序的文檔，了解這些選項(xiàng)。

Once fsck is complete, the filesystem is ready for use.

一旦fsck完成這樣的工作，文件系統(tǒng)就可以使用了。

That certainly beats the fsck process.

這顯然好于fsck進(jìn)程。

If your filesystems weren't unmounted cleanly, you should fsck them first.

如果文件系統(tǒng)沒(méi)有卸裝干凈的話，應(yīng)該首先對(duì)它們進(jìn)行fsck。

Internal snapshots are removed if the fsck command has to modify a JFS2 file system to repair it.

It's based on the solid ext2 filesystem code and it inherits a great fsck tool.

它基于穩(wěn)固的ext2文件系統(tǒng)代碼，并繼承了一個(gè)很好的fsck工具。

The fsck utility, however, is mainly a front-end to file system-specific tools, such as e2fsck (for ext2fs, ext3fs, and ext4fs).
