Ubuntu 12.04 LTS更新 – 错误：“您的系统现在不可用！”

我只是做了apt-get dist-upgrade ，看到了下面的错误：

 cryptsetup: WARNING: failed to detect canonical device of /dev/md1 cryptsetup: WARNING: could not determine root device from /etc/fstab W: mdadm: the array /dev/md3 with UUID 8b1840ac:12c70cae:3fb6082e:e5593158 W: mdadm: is currently active, but it is not listed in mdadm.conf. if W: mdadm: it is needed for boot, then YOUR SYSTEM IS NOW UNBOOTABLE! W: mdadm: please inspect the output of /usr/share/mdadm/mkconf, compare W: mdadm: it to /etc/mdadm/mdadm.conf, and make the necessary changes.

W: mdadm: please inspect the output of /usr/share/mdadm/mkconf, compare W: mdadm: it to /etc/mdadm/mdadm.conf, and make the necessary changes.` 

当我运行/usr/share/mdadm/mkconf的时候，这个文件有所不同：

 ARRAY /dev/md1 level=raid1 num-devices=2 devices=/dev/sda1,/dev/sdb1 ARRAY /dev/md3 level=raid1 num-devices=2 devices=/dev/sda3,/dev/sdb3 

对此：

 ARRAY /dev/md3 metadata=0.90 UUID=8b1840ac:12c70cae:3fb6082e:e5593158 ARRAY /dev/md1 metadata=0.90 UUID=3d78c4fe:0806edff:3fb6082e:e5593158 

我做了这些改变，但是当我运行update-initramfs -u ，我得到这个错误：

• Linux：Gnu-Tar不包括在内
• Ubuntu：迫使进程进入交换或进入内存
• 无法ping多播IP
• 未能为所有来源添加用户
• 长时间运行tmux会话是否会影响服务器，服务器是否需要closures？

 cryptsetup: WARNING: failed to detect canonical device of /dev/md1 cryptsetup: WARNING: could not determine root device from /etc/fstab 

这是我的fstab ：

 /dev/md1 / ext3 defaults 1 1 /dev/sda2 none swap sw /dev/sdb2 none swap sw /dev/vg00/usr /usr xfs defaults 0 2 /dev/vg00/var /var xfs defaults,usrquota 0 2 /dev/vg00/home /home xfs defaults,usrquota 0 2 devpts /dev/pts devpts gid=5,mode=620 0 0 none /proc proc defaults 0 0 none /tmp tmpfs defaults 0 0 

有任何想法吗？

编辑：只是为了澄清，我没有在这台机器上的任何encryption磁盘，所以我不知道为什么cryptsetup什么都说。
