I am having a odd issues my CIFS drive. It won't mount at boot and also when the system has booted, I have tried again with mount -a but no success. It will however mount with the mount -t command and when I unmount this share that does not exist(see code below). It seems that Ubuntu is tracking that it's mounted when df and the actually folder are reporting something different.
This is on a Ubuntu 14.04 LTS server
I will say that this seem to begin when I added a bridge interface to this server for KVM so I am not sure if that has caused this.
