JunOS：密码恢复失败

我正在尝试恢复MX80上的root密码，但是我收到一些错误，并且不知道它们的含义（它不存在，因此建议性的“破坏性”步骤是可以接受的）；

步骤我已采取的措施如下：


在提示下重新启动路由器Hit [Enter] to boot immediately, or space bar for command prompt-我按了空格
我输入boot -s引导到单用户模式
在提示下Enter full pathname of shell or 'recovery' for root password recovery or RETURN for /bin/sh:我输入recovery
进入CLI后，我进入配置模式，然后尝试重置root密码并提交配置；这是我遇到的错误；它们是什么意思，我该如何纠正？它甚至是否需要更正（我想是这样！）：

[edit]
root# set system root-authentication plain-text-password 
New password:
Retype new password:

[edit]
root# commit    
error: could not open database: /var/run/db/juniper.data: No such file or directory
error: Database open failed for file '/var/run/db/juniper.data': No such file or directory
error: commit failed: daemon file propagation failed

[edit]

MX80正在运行JunOS 11.4R1.14。我已重新启动，密码尚未重置。我应该再试一次，还是该路由器出现问题，我应该首先解决？我不想破坏任何东西。

UPDATE

作为对此的更新；今天，我再次进入恢复模式，却什么也没做，我在电话中，路由器位于“ root>”。在电话上呆了几分钟后，路由器突然出现了紧急情况；

Enter full pathname of shell or 'recovery' for root password recovery or RETURN for /bin/sh: recovery
