我没有 RAID 但收到警告 mdadm.conf 没有定义阵列

Question

我安装了 16.04 Server，当我initramfs通过正常的软件包升级升级软件包时，我的日志中也有类似的消息和此消息。

...
Setting up initramfs-tools (0.122ubuntu8.3) ...
update-initramfs: deferring update (trigger activated)
Processing triggers for initramfs-tools (0.122ubuntu8.3) ...
update-initramfs: Generating /boot/initrd.img-4.4.0-38-generic
W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.

这是正常的，还是 Ubuntu 由于某处配置错误而希望找到 RAID？

以下是内容/etc/mdadm/mdadm.conf：

# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
#

# by default (built-in), scan all partitions (/proc/partitions) and all
# containers for MD superblocks. alternatively, specify devices to scan, using
# wildcards if desired.
#DEVICE partitions containers

# auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes

# automatically tag new arrays as belonging to the local system
HOMEHOST <system>

# instruct the monitoring daemon where to send mail alerts
MAILADDR root

# definitions of existing MD arrays

Answer 1

错误说 W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.

我认为，只要没有显示警告ARRAY的线mdadm.conf。

显而易见的解决方案是添加一个：

ARRAY <ignore> devices=/dev/sda

为我工作...
