Mount directory via SSH

To mount directory '/documents/mounted' :

sshfs root@site.com:/web /documents/mounted -ouid=501,gid=20,allow_other,reconnect,volname=RepoSandbox,Ciphers=arcfour,cache=no

'Bad mount point' error appears recurrently, to fixed it :
-- kill the sshfs process
-- umount -l /documents/mounted
-- mount the sshfs again
