VFS(Virtual Filesystem Switch)称为虚拟文件系统或虚拟文件系统转换,是一个内核软件层,在具体的文件系统之上抽象的一层,用来处理与Posix文件系统相关的所有调用,表现为能够给各种文件系统提供一个通用的接口,使上层的应用程序能够使用通用的接口访问不同文件系统,同时也为不同文件系统的通信提供了媒介。 VFS并不是一种...
In this article, we’ll see how to use the‘fsck’or‘e2fsck’command in Linux to repair a corrupted file system. Note: Execute the fsck on an unmounted file systems to avoid any data corruption in the file system. For larger file systems, fsck may take a long time to run depending ...

Linux Directory Structure (File System Structure) Linux File Naming Convention Linux uses a flexible naming convention. We can use any number or letter in a file name. We can also use an underscore, space, period, and comma. Some special characters, such as a question mark, asterisk, and ...
To analyze the entire root directory (“/”), run the following command. *Be aware that scanning the root directory can take significant time.* sudo ncdu -x / The `-x` option is important: it tells `ncdu` to only consider files and directories on the same filesystem as the starting ...
There are risks in migrating data. Back up the data before migration. To extend partitions and file systems on an ECS whose kernel version is greater than 3.6.0, see Expanding Disk Partitions and File Systems (Linux). Prerequisites You have expanded the system disk capacity and attached the ...

While doing initial identification, the only method to determine the disk type is using the serial log as previously examined inIdentify which disk is corrupted. When the disk device is reported in the serial log, errors will be displayed from the Linux kernel module for the filesyst...
