我的/etc/fstab
是空的,当我重新启动时它挂了,我需要添加到uuid
吗etc/fstab
?
答案1
是的,您需要在 /etc/fstab 中指定 UUID。。。它应该如下所示,具有通用设置、单个分区、挂载点“/”和非加密交换。
# /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/sda3 during installation
UUID=c930ecd2-929b-4eef-90d3-60a9ee420f95 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda1 during installation
UUID=d4bd9a66-3249-4ee4-b92e-ea1d3c31c113 none swap sw 0 0
确保您的 /etc/fstab 文件为空。您可能只需要更改 /etc/fstab 条目的 UUID(如果它们由于某种原因而发生了变化,尽管这种情况不太可能发生)。
还,如果您使用加密文件系统,该文件会略有不同。
