mount了mfs后，重新挂载之后，出现如下错误：
/usr/local/mfs/bin/mfsmount -H 192.168.103.101 /mnt/
fuse: bad mount point `/mnt/’: Transport endpoint is not connected
see: /usr/local/mfs/bin/mfsmount -h for help
解决方法：
1、kill进程；
2、umount
3、重新mount
ps aux | grep mfs
umount –l /mnt/usr/local/mfs/bin/mfsmount -H 192.168.103.101 /mnt/
