`NamenodeFsck`类是关键部分，如果没有指定打印参数，默认不进行打印。当指定了打印参数时，结果才会显示在屏幕上。该类包含入口函数，引导执行检查流程。流程中包括查找损坏块队列的大小，并在非零的情况下继续执行。结果将被存储并返回，最后在`listCorruptFileBlocks`中进行打印。使用`hdfs fsck`命令的...
-blocks 打印出block报告 -locations 打印出每个block的位置 -racks 打印出data-node的网络拓扑结构 默认情况下,fsck会忽略正在写的文件,使用-openforwrite可以汇报这种文件 下面是是一个运行的命令例子: [search@fse01 hadoop]$ bin/hadoop fsck / -files ...
块组:Ext4文件系统的全部空间被划分为若干个块组,每个块组内的结构都是大致相同的。 块组描述符表:每个块组都对应一个块组描述符,这些块组描述符统一放在文件系统的前部,称为块组描述符表。每个块组描述符大小为32字节,其主要描述块位图、i-节点位图及i-节点表的地址等信息。 超级块(Superblock):用于存储文件...
