If you use the device mapper multi-path (DMMP) tool for your multi-path storage, then you can use a friendly name for your root file system to avoid the device being renumbered by DMMP after reboot.
如果将设备映射程序多路径(DMMP)工具用于多路径存储，则可以将友好的名称用于根文件系统以避免设备在重新启动后被dmmp重新编号。
The structure and size of a file depends on the underlying file system—the subsystem that persists the file data to a physical device.
文件的结构和大小取决于底层文件系统 —即把文件数据存储到物理设备上的子系统。
The second column contains the mount point, the location for that device in the file system.
第二列是装载点，也就是设备在文件系统中的位置。
Use the label, UUID, or friendly name instead of the device name for the root file system mount.
对根文件系统挂载使用标签、UUID或友好的名称而非设备名称。
Using the following command to check the ID for your root file system device with the device UUID you get from step 1.
使用以下命令检查带有从第1步中得到的设备UUID的根文件系统设备的ID。
The reason for the additional LUN is that the root file system is in use at this time and DMMP cannot add it to the device map; therefore, you cannot get that name for the root partition.
添加lun的原因是，使用的根文件系统和DMMP无法将它添加到设备映射；因此，无法对根分区应用该名称。
Next, mount the file system onto a mount point using the loop device (see Listing 2).
接下来，使用循环设备将该文件系统挂载到一个挂载点上（如清单 2 所示）。
The CD is added to the file system and the CDROM device is locked so that it cannot be accidentally ejected.
CD 就会被添加到文件系统中，CDROM设备会被锁定以使它不会被意外弹出。
From this simple demonstration, it's easy to see how powerful the Linux file system (and the loop device) can be.
通过这个简单的演示很容易体会到Linux文件系统(和循环设备)是多么强大。
This file is a simple Linux shell script that contains all commands for loading device drivers to system memory.
此文件是包含将设备驱动程序载入到系统内存中的所有命令的简单Linuxshell脚本。
For example, in Unix, devices appear to the application as files on the file system; meaning the application communicates with the device by performing file reads and writes.
例如，在Unix中，设备对于应用程序是作为文件系统上的文件出现的；意味着应用程序通过执行文件读写与设备通信。
Some systems do not have this option but do have the -x command-line option, which only includes the file usage for files on the same device or file system as the path you specify.
有些系统没有这个选项，但是有- x命令行选项，该选项仅包含与您所指定的路径相同的设备或文件系统中的文件使用情况。
The root directory entry (dentry) object is cached here also, as is the block device on which this file system resides.
根目录条目(dentry)对象也缓存在这里，因为它是文件系统所在的块设备。
For example, as shown in Listing 3, the /mnt/yellowmachine directory is a mountpoint for a Network File System (NFS) mount of the /mnt/disk1 directory on the 192.168.6.166 device.
例如，如 清单3 所示，/mnt/yellowmachine目录是192.168.6.166设备上的 /mnt/disk1 目录的NetworkFile System (NFS) 挂载点。
The DataPower device restarts itself automatically in conjunction with throttle configurations such as memory or file system constraints.
DataPower设备在重启时会自动进行节流(throttle)设置，如内存或文件系统限制。
The used column shows the number of blocks that have been used on the file system or device.
used 列显示了该文件系统或设备上已使用的块数。
With tools that pretended to be iTunes, the device allowed itself to be accessed and its file system to be modified.
当工具伪装成ITunes，设备允许自己被访问且文件系统也可以被修改。
Change PCI Device Boot Priority to the adapter your root file system disk is using (as in Figure 2 below), if your Linux is installed on a local Planar SAS disk.
如果您的Linux安装在本地PlanarSAS磁盘中，请将PCIDeviceBootPriority更改为根文件系统磁盘正在使用的适配器(如下面的图2所示)。
