Server stuck on boot in rescue mode
I have no idea what to do ...

mount: /dev/sda3: can't find in /etc/fstab.

Above is the error i come across when I try to mount

Can anyone help me? I also cannot click out of rescue mode on the OVH control panel.

OVH have not responded to my support ticket either.
