As you can see in Figure 4-1, if you want to access the data in a file, you need to get the appropriate partition location from the partition table and then search the filesystem database on that partition for the desired file data. 如图4-1所示,如果您想访问文件中的数据,您需要从分区...
The root filesystem can be specified as a device file, such as in this example: 根文件系统可以指定为设备文件,例如在这个例子中: ```sh root=/dev/sda1 However, on most modern desktop systems, a UUID is more common (see 4.2.4 Filesystem UUID): 不过,在大多数现代桌面系统中,UUID 更为常...
使用udisks_client_get_block_for_dev() 通过1中的对象 + 设备名(比如:/dev/sda)获取到块 UDisksObject 根据UDisksObject 可以获取到 UDisksDrive 或者 UDisksFilesystem,通过这两个对象可以分别操作设备和文件系统(回想一下前边 d-feet 操作设备的流程)。 最后,udisks 的 API 当然不止这些功能,还可以操作分区表...
sudo blkid /dev/sdc1 /dev/sdc1: UUID="<UUID>" BLOCK_SIZE="4096" TYPE="xfs" PARTLABEL="Linux filesystem" PARTUUID="<PARTUUID>" 如果您在重新建立分割區之後看不到 /boot 文件系統,這表示 /boot 數據已不存在。 您必須重新建立 /boot 文件系統(使用 /etc/fstab /boot 專案中的相同UUID...
vfs_caches_init() 会用来初始化基于内存的文件系统 rootfs。在这个函数里面,会调用 mnt_init()->init_rootfs()。这里面有一行代码,register_filesystem(&rootfs_fs_type)。在 VFS 虚拟文件系统里面注册了一种类型,我们定义为 struct file_system_type rootfs_fs_type。

How to Change UUID of Your Filesystems ChangingUUIDof a filesystem is fairly easy. To do this, we are going to usetune2fs. For the purpose of this tutorial, I will change theUUIDon my second partition/dev/sdb1, yours may vary, thus make sure you are changing the UUID of the desire...
