在今天的文章中，我们讨论Data Extractor RAID版的BtrFS文件系统功能。
In today’s article we talk about BtrFS file system functionality of  the Data Extractor RAID Edition.

Btrfs （B-tree文件系统）是基于 copy-on-write（COW）原理的文件系统。
Btrfs (B-tree file system) is a file system based on the copy-on-write (COW) principle.

Btrfs旨在解决在Linux文件系统中缺少池，快照，校验和和整体多设备的问题。
Btrfs is intended to address the lack of pooling, snapshots, checksums, and integral multi-device spanning in Linux file systems.

数据提取器RAID版完全识别BtrFS元数据。PC-3000用户可以使用Data Extractor RAID Edition中的元数据自动检测来构建此系统。
BtrFS metadata is fully recognized by the Data Extractor RAID Edition. PC-3000 users can build this system using metadata autodetection in the Data Extractor RAID Edition.

首先，我们必须添加所有的RAID成员
Firstly, we have to add all RAID members

所以我们可以使用“基于RAID元数据的自动检测”来设置配置
So we can use ‘Autodetection based on RAID metadata’ for setting the configuration

基于元数据分析的结果，提出了三种可能的配置。
Three possible configurations are suggested based on the result of metadata analysis.

我们对最大容量的配置感兴趣。
We are interested in configuration with the largest capacity

右键单击配置并尝试编辑它。
Right-click on the configuration and try to edit it.

该配置包含12个成员，其中2个丢失。但是，配置的级别是RAID 6，它有两种用于数据完整性的冗余块（XOR和RS）。因此，两个缺少的驱动器并不重要。
The configuration contains of 12 members and 2 of them are missed. However, the level of the configuration is RAID 6, which has two type of redundancy blocks for data integrity (XOR and RS).  As such, two missed drives are not crucial.

如果我们打开资源管理器模式，我们可能会看到Btrfs超级块已被读取
If we open the Explorer mode we may see that Btrfs superblock had been read

文件结构可用
File structure is available

桌面上的假期照片能正常打开
And the nice vacation photos are at your desk.

这些是BtrFS支持的基本功能。有两个丢失的驱动器，但是PC-3000有能力在丢失的成员的情况下恢复数据。然而，对于复杂的情况，需要额外的技能和操作。我们将在下一篇文章中讨论这个问题
These are  the basic features of BtrFS support. There were two missed drives, but PC-3000 is capable to recovering the data with missed members. However, for complex cases, additional skills and operations are required. We will discuss it in the next article…
