• 網(wǎng)絡(luò)索引節(jié)點(diǎn)；文件總數(shù)；文件實(shí)體

例句

Typically, there is an adequate number of inodes associated with a file system, but running out of inodes is always a possibility.

通常，與一個(gè)文件系統(tǒng)相關(guān)聯(lián)的inode的數(shù)目足夠多，但耗盡inode的可能性始終存在。

The number of inodes that can be created in a filesystem is dynamic and it is only limited by the amount of free space in the filesystem.

在文件系統(tǒng)中可以創(chuàng)建的索引節(jié)點(diǎn)的數(shù)目是動(dòng)態(tài)變化的，并且只受到文件系統(tǒng)中剩余空間的限制。

During times like this, you may run into messages that inodes need to be repaired or that an error exists.

此時(shí)，您可能會(huì)碰到一些需要修復(fù)inode或者存在錯(cuò)誤的消息。

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)。

This structure defines the set of functions for managing inodes within the file system.

這個(gè)結(jié)構(gòu)定義一組用來(lái)管理這個(gè)文件系統(tǒng)中的inode的函數(shù)。

Because hard links point to an inode, and inodes are only unique within a particular file system, hard links cannot cross file systems.

由于硬鏈接指向一個(gè)inode，且inode僅在特定文件系統(tǒng)內(nèi)是惟一的，硬鏈接不能跨越文件系統(tǒng)。

When the file system is scanned at mount time, the valid inodes can be quickly identified.

在掛載期間掃描文件系統(tǒng)時(shí)，可以快速標(biāo)識(shí)有效的inode。

It doesn't take much to make a superblock dirty, cause fragmentation, mess up inodes, or cause repeating JFS errors in the errpt.

無(wú)需多費(fèi)勁就可以讓超塊變臟、造成存儲(chǔ)碎片、搞亂存儲(chǔ)節(jié)點(diǎn)或引起errpt反復(fù)出現(xiàn)JFS錯(cuò)誤。

In UNIX, directories are actually files that have a few additional settings in their inodes.

在UNIX中，目錄本身就是文件，只是在它們的inode中使用了一些附加的設(shè)置。

mke2fs is the utility used to create an ext2 filesystem -- creating the super block, inodes, inode table, and etc -- on any device.

mke2fs是用于在任何設(shè)備上創(chuàng)建ext2文件系統(tǒng)的實(shí)用程序—它創(chuàng)建超級(jí)塊、索引節(jié)點(diǎn)以及索引節(jié)點(diǎn)表等等。

Only file system inodes are stored permanently, where dentry objects are used to improve performance.

僅永久儲(chǔ)存文件系統(tǒng)inode，dentry對(duì)象的目的是改善性能。

If you are copying from one file system to another of exactly the same type, the number of inodes used should be identical.

如果您將文件從一個(gè)文件系統(tǒng)復(fù)制到另一個(gè)與其類型完全相同的文件系統(tǒng)，那么所使用的索引節(jié)點(diǎn)的數(shù)目應(yīng)該是相等的。

Files within a file system are represented uniquely as inodes.

文件系統(tǒng)中的文件由inode唯一地表示。

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

通過使用fsck命令，您還可以縮小受損inode的搜索范圍。

Note that because files are used to represent other types of objects, such as devices or memory, inodes are used to represent them also.

注意，因?yàn)?/c>文件用于表示其他類型的對(duì)象（比如設(shè)備或內(nèi)存），所以也使用inode來(lái)表示它們。

Exofs maps inodes to the object identifiers (OIDs) in the object system.

exofs將inode映射到對(duì)象系統(tǒng)中的對(duì)象標(biāo)識(shí)符（OID）。

You will see inodes again later in this article and also in the article Create and change hard and symbolic links (see the series roadmap).

您將在本文后面以及創(chuàng)建和修改硬鏈接和符號(hào)鏈接（參見學(xué)習(xí)Linux，101：LPIC-1路線圖）中再次見到有關(guān)inode的介紹。

Hopefully, after reading this article, you understand inodes better, their importance to AIX, and also how to manage them.

希望在閱讀完本文之后，您可以更好地了解inode、它們對(duì)于AIX系統(tǒng)的重要性，以及如何管理它們。

When this makes some sectors or inodes invalid, you will end up losing valuable data.

當(dāng)這導(dǎo)致某些扇區(qū)或節(jié)點(diǎn)無(wú)效時(shí)，將最終丟失寶貴的數(shù)據(jù)。

The most-recently used inodes and dentries are kept in the inode and directory cache respectively.

inode和目錄緩存分別保存最近使用的inode和dentry。

XFS is also very efficient when it comes to the management of inodes.

當(dāng)對(duì)索引節(jié)點(diǎn)進(jìn)行管理時(shí)，XFS也是很有效的。

Two caches exist for file system objects (inodes and dentries), which I'll define shortly.

有兩個(gè)針對(duì)文件系統(tǒng)對(duì)象的緩存（inode和dentry）。

For example, inodes can be allocated with alloc_inode or deleted with destroy_inode.

例如，可以用alloc_inode分配inode，用destroy_inode刪除inode。

Knowing how to work with inodes in UNIX can save a lot of time and frustration.

了解如何在UNIX中使用inode可以節(jié)約大量的時(shí)間，并提高工作效率。
