挂载点 [UUID] 不存在（Ubuntu 14.04 LTS）

挂载点 [UUID] 不存在（Ubuntu 14.04 LTS）

我有一台 Ubuntu 台式机，其中 1 个 SSD 已安装系统 (/dev/sda)，4 个 HDD 在软磁盘阵列 (/dev/md0、sd[be]) 中运行。目前，每当我打开 PC 时，Ubuntu 最初都无法启动，并显示：

Mount point bcb7c4d3-574e-43f0-9f73-658ab99652c4 does not exist

如果我无论如何都按 S 键启动，系统就会正常启动，尽管 raid 阵列不会自动启动（即使已配置为自动启动），但我可以手动将其安装Disks。

这是我的/etc/fstab/文件：

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name     devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type> <options>       <dump>  <pass>
# / was on /dev/sda1 during installation

# swap was on /dev/sda5 during installation

当谈到编辑 fstab 时，我不知道自己在做什么，并且认为最好在开始之前先在这里问一下。

这是‘fdisk -l’的输出：

有人可以帮助我使启动/安装正常进行吗？

编辑：blkid 输出：

按照 Organic Marble 的建议并注释掉以下行可以解决这个问题：

/dev/disk/by-uuid/bcb7c4d3-574e-43f0-9f73-658ab99652c4 /mnt/bcb7c4d3-574e-43f0-9f73-658ab99652c4 auto nosuid,nodev,nofail,x-gvfs-show 0 0

并/etc/fstab重新启动。系统现在可正常启动，并且 RAID 阵列可自动正常安装。
