以前，Debian 挂载的 win10 cifs 运行良好。访问cifs文件时突然提示“输入/输出错误” 查看ls /proc/fs, cifs is missing
甚至 nfs 服务器也无法启动。
我不应该做任何修改系统配置，只是将ubuntu 10.10的modinfo复制到debian 9环境，半小时后出现上述现象。
重新加载 cifs.ko 失败
root@debian llg
$ modprobe cifs
...
do nothing
没有到岸价
$ ls -l /proc/fs/
总用量 0
dr-xr-xr-x 6 root root 0 3月 26 14:04 ext4
dr-xr-xr-x 6 root root 0 3月 26 14:04 jbd2
dr-xr-xr-x 2 root root 0 3月 26 14:04 nfsd
挂载 cifs 服务器失败
sudo mount -t cifs //192.168.1.51/project -o uid=1000,gid=1000,nounix,noserverino,username=Administrator /mnt/cifs/project/
mount error: cifs filesystem not supported by the system
root@debian llg
$ service nfs-kernel-server restart
