[arch-general] VPS can't access after update filesystem?

[Bill Sun]

I got the error message:

ERROR: device '/dev/xvda1' not found. Skipping fsck.
ERROR: Unable to find root device '/dev/xvda1'.
You are being dropped to a recovery shell
    Type 'exit' to try and continue booting
sh: can't access tty; job control turned off
