当我在mdadm中运行扫描时，我收到此消息：
me@server:/sbin$ mdadm --monitor --scan
mdadm: unreconised word on DEVICE line: UUID=8eac0a3d-a22c-1a92-6ed9-f147f3dea64f

我的/etc/mdadm/mdadm.conf文件的内容如下所示：

是语法错误吗？或者它会是什么？
就我的功能而言，RAID阵列的功能正常。它正在安装，我可以使用它。
如果我能找出导致该消息的原因，我会感觉更舒服。
答案 0 :(得分：1)
根据mdadm.conf的手册页，DEVICE行必须采用以下格式：
DEVICE /dev/hda* /dev/hdc*
DEV /dev/sd*
DEVICE /dev/disk/by-path/pci*
DEVICE partitions
默认值为DEVICE partitions containers，这基本上意味着扫描所有分区和任何寻找阵列成员的RAID阵列。似乎UUID不是可以在/etc/fstab中使用的有效标识符。通常，您不必指定磁盘，因为DEVICE行仅扫描设备以查找阵列成员而不要求它是阵列的一部分。如果您需要指定设备，请在/dev/disks/by-*/中找到要使用的相应符号链接。
