正如标题所述，我无法安装我的 RAID 阵列。这是我的 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
ARRAY /dev/md/127 metadata=1.1 UUID=7228e3bb:e2927657:05bd319c:a646a849 name=dc.sec.net:0
# This file was auto-generated on Tue, 27 Sep 2016 20:52:52 +0530
# by mkconf $Id$
这是我的挂载命令 sudo mount /dev/md127 /media/md 的结果
mount: wrong fs type, bad option, bad superblock on /dev/md127,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
检查系统日志时我注意到

我尝试运行 fsck，结果
fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/md127
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
我运行了 e2fsck -b 8193 /dev/md127 和 e2fsck -b 32768 /dev/md127 并得到了以下结果。
e2fsck 1.42.13 (17-May-2015)
