使用 mdadm 创建的 RAID1 阵列；发生电源故障时正在重建阵列。回来后，阵列似乎已经死了。
# cat /proc/mdstat
Personalities : [raid1]
md0 : inactive sdb1[2](S) sda1[3](S)
15627751424 blocks super 1.2
# mdadm --stop /dev/md0
mdadm: stopped /dev/md0
# mdadm --assemble /dev/md1 /dev/sda1 /dev/sdb1
mdadm: /dev/md1 assembled from 0 drives and 1 rebuilding - not enough to start the array.
我不知道为什么它说 0 个驱动器 - 我预计 1 个重建，但另一个驱动器应该没问题。我真的不想意外地做任何破坏性的事情——我应该怎么做才能让阵列恢复到可以在其上运行 fsck 的状态？

查看带有 xxd 的驱动器，两者似乎仍然包含数据。这是我自己可以合理管理的事情，还是该找数据恢复公司了？
编辑：Wazoox 的回答有效。
# mdadm --assemble --scan --force
mdadm: forcing event count in /dev/sda1(1) from 1079799 upto 1079809
mdadm: /dev/md0 has been started with 1 drive (out of 2) and 1 rebuilding.
