我有一块来自 Javelin S4（类似于 Promise NS4600N）机箱的硬盘，它被设置为单磁盘 RAID0，我曾尝试将其添加到我的 Linux Ubuntu 服务器（14.x）通用“Linux 3.13.0-49-generic”中，根据我所读到的内容，我认为 FS 类型是 xfs。我还有一个来自 Promise NS4300N 的磁盘，我可以添加（ext3）没有问题，同样的单磁盘 RAID0 格式。
每当我尝试安装 XFS 设备时，都会收到错误“功能未实现”。
fdisk -l（仅提供相关项目）：

此信息与安装正常的 ext3 设备相同。
当我执行以下任何一项操作时：
sudo mount -t xfs /dev/vg002/lv001 /hdd/volume2
sudo mount -t xfs /dev/mapper/vg002-lv001
sudo mount /dev/vg002/lv001 /hdd/volume2
sudo mount /dev/mapper/vg002-lv001
I just get Function not implemented.
我已经安装了 xfsprogs 和 xfsdump
我已经尝试过 Ubuntu 服务器和 Ubuntu 桌面中的选项
我已经运行了 xfs-repair，首先使用 -n，然后不带无操作开关：
sudo xfs_repair -v /dev/mapper/vg002-lv001

我已经验证 xfs 支持 /procs/filesystems 并且它没有 nodev（没有 /etc/filesystems）
我相信 HDD 块大小为 4096，并且已执行 getconf PAGE_SIZE，返回值为 4096
a dmesg | tail yields:

我还在两个不同 NAS 的两个硬盘上运行了此命令：
sudo file -s /dev/sda
/dev/sda: LVM2 PV (Linux Logical Volume Manager), UUID: KNAIIR-rtHE-ucTO-cWT4-Zke0-7NVX-7WNpD0, size: 2000331800576

使用 lvdisplay 命令，我确实注意到它有一个 nswap 实体，而其他 ext3 设备没有。不确定这是否意味着什么（抱歉，我有点菜鸟，或者至少不太精通管理 Linux 基础设施）。
有人对我还没有尝试过的方法有什么想法吗？有什么建议吗？数据没问题，我只是希望能够将数据从一个磁盘传输到另一个磁盘，而不必通过网络进行传输 - NAS > 工作站 > NAS - 需要很长时间。
谢谢
