FILESYSTEM

check sshfs is fine:

sshfs -o allow_other root@116.203.202.210:/mnt/ /mnt/
umount /mnt/

add this to /etc/fstab:

sshfs#root@116.203.202.210:/mnt/        /mnt/   fuse    defaults,user,allow_other,reconnect,delay_connect,ConnectTimeout=5,ServerAliveInterval=5,IdentityFile=/root/.ssh/id_rsa 0 0

and reboot
