  2. In ext3, the journaling code uses a special api called the journaling block device layer, or jbd

    在ext3里,日誌記錄代碼使用一個特殊的稱為「日誌記錄塊設備」層或jbd的api 。
  3. It s quite a nice arrangement, and because the jbd is being developed as a separate, generic entity, it could be used to add journaling capabilities to other filesystems in the future

    這是很好的安排,因為jbd是作為一個單獨的、一般實體而開發的,將來它可以用於向其它文件系統添加日誌記錄能力。
  4. Which means that the jbd uses complete physical blocks as the underlying currency for implementing the journal

    ,這意味著jbd使用完整的物理塊,作為實現日誌的主要媒介。
  5. Jbd takes another, and in some ways better, approach

    Jbd使用另外一種(從某種意義來說是更好的)方法。

    關于jbd管理的ext3日誌有一些巧妙的特性。
  7. Because both data and metadata are journaled, jbd can use the journal to bring both metadata

    因為數據和元數據都被記錄, jbd可以使用日誌將元數據
  8. Rather than recording spans of bytes that must be changed, jbd stores the complete modified filesystem blocks themselves

    Jbd存儲完整的被修改的文件系統塊本身,而不是記錄必定會被更改的位元組范圍。
  9. By doing so, the jbd is given the appropriate opportunities to manage the journal on behalf of the ext3 filesystem driver

    通過執行這些操作,給予了jbd代表ext3文件系統驅動程序管理日誌的適當機會。
  10. In this mode called " data journal " mode, the jbd journals all changes to the filesystem, whether they are made to data or metadata

    在這種方式下(稱之為「 data = journal 」方式) , jbd將所有對數據和元數據的更改都記錄到文件系統中。
  11. For example, the ext3 filesystem code will inform the jbd of modifications it is performing, and will also request permission from the jbd before modifying certain data on disk

    例如, ext3文件系統代碼將正在執行的修改告知jbd ,並且還會在修改磁盤上包含的特定數據之前請求jbd的許可。
