	Creating a Btrfs Layout	创建一个Btrfs布局
	_Btrfs_ is a type of file system, but it has several features characteristic of a storage device. It is designed to make the file system tolerant of errors, and to facilitate the detection and repair of errors when they occur. It uses checksums to ensure the validity of data and metadata, and maintains snapshots of the file system that can be used for backup or repair.
	Creating a Btrfs layout is somewhat similar to LVM (described in xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-lvm[Creating a Logical Volume Managament (LVM) Layout]) with slightly different terminology. A Btrfs _volume_ is the equivalent of an LVM volume group, and a Btrfs _subvolume_ is similar to a LVM logical volume. An important difference to note is how [application]Anaconda reports sizes for separate mount points: For LVM, the exact size of each logical volume is shown next to each mount point in the left pane, while with Btrfs, the total size of the entire volume is shown next to each subvolume.
	Some partition types - notably the `/boot` and `/usr` directories and the BIOS Boot and EFI partitions - can not be placed on Btrfs subvolumes. Use standard physical volumes for them (or an LVM logical volume for `/usr`). See xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-recommended[Recommended Partitioning Scheme] for more information.

	Follow the procedure below to create Btrfs volumes and subvolumes:	按以下流程来创建Btrfs卷和子卷：
	Creating Btrfs Subvolumes and Volumes	创建Btrfs子卷和卷
	Click the `+` button at the bottom of the list showing existing mount points. A new dialog window will open.	按下现存挂载点列表底部的“+"按钮，然后将开启一个新的对话框。
	In the new dialog window, specify a mount point for which you want to create a separate logical volume - for example, `/`. Optionally, specify a size for the volume using standard units such as MB or GB (for example, `50GB`). Then, click `Add mount point` to add the volume and return to the main partitioning screen.
	When creating a mount point for swap on Btrfs, specify the mount point as `swap`.	当在Btrfs上创建一个交换分区挂载点时，需要指定挂载点类型为“swap”。
	The mount point has now been created using the default settings, which means it has been created as an LVM logical volume. Select the newly created mount point in the left pane to configure it further, and convert it to a Btrfs subvolume by changing the `Device Type` option to `Btrfs`. Then, click `Update Settings` in the bottom right corner of the screen.
	In the `Volume` menu, you can see that the subvolume has been assigned to an automatically created volume, which is named after the {PRODUCT} variant you are installing (for example, `fedora-server00`. Click the `Modify` button under the drop-down menu to access the volume settings.
	In the `Configure Volume` dialog, you can change the volume's name, its `RAID level` (see xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-filesystems[Device, File System and RAID Types] for information about available RAID types), and you can also specify which physical devices (disks) this volume should reside on. You can select one or more disks which will be used to hold this volume by holding down kbd:[Ctrl] and clicking each disk in the list.
	If you select a redundant RAID type (such as `RAID1 (Redundancy)`), the volume will take up twice its actual size on your disks. A 5 GB volume with RAID1 will take up 10 GB of space.
	You can also make sure that the volume is encrypted by selecting the `Encrypt` option; this will enable LUKS encryption for the entire volume. See the [citetitle]_{PRODUCT} Security Guide_, available at link:++https://docs.fedoraproject.org/++[], for information about LUKS disk encryption.
	Additionally, you can set a fixed size for the volume by selecting the `Fixed` option from the `Size policy` menu and entering a size for the volume group.	此外，你可以通过选择“大小策略”中的“固定大小”的选项、然后对一个卷组输入一个大小参数的方式，来设置卷为一个固定的大小。
	After you finish configuring the Btrfs volume settings, click `Save` to return to the main `Manual Partitioning` screen.	在你配置完Btrfs卷的设置之后，点击“保存”来返回主“手动分区”屏幕。
	If you need to create more than one Btrfs volume, open the `Volume` drop-down menu and select the `Create a new volume group` option. A new dialog window will open, identical to the one described in the previous step. Again, select a name, storage devices, encryption settings, RAID level and size policy for the new volume, and click `Save`. The new volume will then become available in the `Volume Group` drop-down menu; you can then go through your existing mount points and change this setting to assign them to a different volume.
	Configure other settings specific to the subvolume - its `Mount Point`, `Desired Capacity`, `File System`, and `Name`. Press `Update Settings` to apply any changes to the configuration.
	Repeat this procedure for any additional Btrfs subvolumes you want to create. Note that when creating additional subvolumes, a new volume is not automatically created each time; instead, any additional subvolumes are assigned to an existing volume.	对于你想创建的所有Btrfs子卷，你都要重复这个流程。注意：当创建其他的子卷时，不会每次都创建一个新的卷；相反地，新创建的子卷都会默认分配到已有的卷之下。
