请阅读编辑，行为已经改变
我在运行Ubuntu 12.04LTS的Microsoft Azure上有一台机器。我设置MySQL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/停止机器，在启动时磁盘没有安装，MySQL服务无法在没有人工干预的情况下启动。
我按照指南说明编辑fstab会完成我需要的工作。这些是我采取的步骤（/ dev / sdc1是自动挂载的驱动器）：
sudo 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"
sudo nano / etc / fstab
UUID=6ae2c935-d4f7-47e8-8be0-23ff41d12ff2 / ext4 defaults,discard 0 0
我添加了以下行
UUID=ac28921e-c8aa-4ab2-8422-d985f64c722b /mnt/datadrive ext4 defaults 0 2
sudo mount / dev / sdc1 / mnt / datadrive
NOT ANYMORE重新启动后，我找不到新的安装点和新驱动器，我必须重做该过程。
我该怎么办？
编辑：我认为我没有真正改变任何事情，但行为已发生变化。我尝试将这些指令放在/etc/init.d/mysql中作为下面的第一行：
#!/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}"
但没有改变，所以我删除了它们。 现在我遇到的行为如下：
每次重启 df 都会提供以下输出：
user@Database:~$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 30235684 1115576 27584520 4% /

/dev/sdb1 139334632 192000 132064848 1% /mnt
如果我检查/ mnt / datadrive中的内容，我发现什么都没有。奇怪的是sdb1和sdc1的大小是相同的，即使sdc1应该是TEN倍大，正如 fdisk -l </ strong>
中所指出的那样user@Database:~$ sudo fdisk -l

所以我尝试卸载驱动器，这是我收到的消息：
user@Database:~$ sudo umount /dev/sdc1
umount: /mnt/datadrive: not mounted
我继续重新安装驱动器，内容又回到原来的位置：
user@Database:~$ sudo mount /dev/sdc1 /mnt/datadrive
user@Database:~$ df
