当我在CentOS 5服务器的已安装根分区上运行只读fsck时，会发现一些错误。 但是，在下次启动时运行强制检查没有find任何！
以下是挂载的只读检查的结果：

touch /forcefsck echo -n "-y" > /fsckoptions
这不会强制fsck在下次启动时运行，“-y”选项应该自动修复所有错误，但在启动期间检查不会find任何错误。 但是，一旦安装了文件系统并且再次运行只读检查，它将find所有相同的错误。
谢谢你的时间，

挂载的文件系统在磁盘上不一致。 不要检查已安装的文件系统。 直接从马口：“但是，即使这样做是安全的，如果文件系统安装，由e2fsck打印的结果是无效的。 -E2FSCK（8）
