(nvme0n1p1)：已重新安装。选项：错误=remount-ro 
$ dmesg | grep nvme
[    1.017031]  nvme0n1: p1 p2 p3 p4
[    7.487584] EXT4-fs (nvme0n1p1): mounted filesystem with ordered data mode. Opts: (null)
[    7.624166] EXT4-fs (nvme0n1p1): re-mounted. Opts: errors=remount-ro
[    8.472627] EXT4-fs (nvme0n1p2): mounted filesystem with ordered data mode. Opts: (null)
[    8.475500] EXT4-fs (nvme0n1p3): mounted filesystem with ordered data mode. Opts: (null)
  1. 这是什么re-mounted. Opts: errors=remount-ro意思？
  2. 需要采取什么样的纠正措施来解决这个错误？

注意：nvme0n1p1 是托管 / 的逻辑分区。

/etc/fstab

通常可以在 mount(8) 手册页中找到挂载选项的文档，请尝试“man mount”或以下 URL： http://manpages.ubuntu.com/manpages/xenial/man8/mount.8.html

错误={继续|重新安装-ro|恐慌}定义遇到错误时的行为。（忽略错误并将文件系统标记为错误并继续，或者以只读方式重新挂载文件系统，或者崩溃并停止系统。）默认值在文件系统超级块中设置，可以使用 tune2fs(8) 进行更改。
