软件 RAID 上的 LUKS 未在启动时安装

软件 RAID 上的 LUKS 未在启动时安装

mdadm我正在尝试在 14.04.1 LTS(GNU/Linux 3.8.13.26 armv7l)(Odroid U3)上设置的软件 RAID 上使用 LUKS 设置加密磁盘。

问题是 LUKS 容器在启动时不会自动解锁,我不知道为什么或在哪里寻找问题。

问题

ext4如果我使用 格式化软件 RAID并将其放入 fstab 中以进行自动挂载,则该软件 RAID 可以正常工作。此外,如果我单独使用 LUKS(不使用 RAID,只使用 ),它也可以正常工作,并且设备在配置时/dev/sda1会显示在中。/dev/mapper/etc/crypttab

问题出现在将两者结合起来时。RAID 设备显示为,/dev/md0但 LUKS 容器不会自动安装到/dev/mapper/crypt。另一方面,启动后使用没有任何问题。此外,我在设置后sudo cryptdisks_start crypt运行(见下面的输出)。sudo update-initramfs -u -k all/etc/crypttab

管理

sudo cat /proc/mdstat输出结果如下:

Personalities : [raid1]
md0 : active raid1 sdb1[1] sda1[0]
      976596800 blocks super 1.2 [2/2] [UU]
      [>....................]  resync =  0.6% (6345024/976596800) finish=1342.7min speed=12042K/sec

unused devices: <none>

其中/etc/mdadm/mdadm.conf有以下一行:

ARRAY /dev/md/0 metadata=1.2 UUID=f2c7b09f:71620ae5:7b6ec321:e9ce02cc name=odroid:0

据我所知,这还算可以。
