请阅读编辑，行为已改变自动挂载VHD
我运行Ubuntu 12.04LTS在微软Azure的机器。我将MySQL设置为将其数据文件夹放在附加的1TB VHD上。 问题是，如果我重新启动/停止计算机，启动时磁盘没有挂载，MySQL服务无法在没有人工交互的情况下启动。
我跟着一个指南，说编辑fstab会做我所需要的。这些是我所采取的步骤（的/ dev/SDC1是挂载的驱动器）：
- 须藤MKDIR的/ mnt/datadrive
- 须藤CHOWN用户-R/MNT/datadrive
须藤BLKID
/dev/sda1: LABEL="cloudimg-rootfs" UUID="6ae2c935-d4f7-47e8-8be0-23ff41d12ff2" TYPE="ext4" /dev/sdb1: UUID="ad260fa5-200a-4a62-a43a-1aed2d91c01e" TYPE="ext4" /dev/sdc1: UUID="ac28921e-c8aa-4ab2-8422-d985f64c722b" TYPE="ext4"- 须藤CP/etc/fstab中/etc/fstab.bak
须藤纳米/ etc/fstab中
UUID=6ae2c935-d4f7-47e8-8be0-23ff41d12ff2 / ext4 defaults,discard 0 0添加以下行
UUID=ac28921e-c8aa-4ab2-8422-d985f64c722b /mnt/datadrive ext4 defaults 0 2须藤设置/ dev/SDC1到/ mnt/datadrive
不再重新启动后，我不能找到新的安装点和新的驱动器，我必须重做程序。
我该怎么办？
编辑：我不认为我真的改变了什么，但行为已经改变。我试图把里面/etc/init.d/mysql这些说明如下的第一行：
#!/bin/sh -e
# upstart-job
#
# Symlink target for initscripts that have been converted to Upstart.
mkdir /mnt/datadrive <--- inserted line
chown user -R /mnt/datadrive <--- inserted line
mount /dev/sdc1 /mnt/datadrive <--- inserted line
set -e
INITSCRIPT="$(basename "$0")"
JOB="${INITSCRIPT%.sh}"
，但什么都没有改变，所以我把他们赶走。 现在我遇到的问题是：
在每次重新启动DF给出了下面的输出：

至于问这是dmesg的内容：
