Storage WD My Cloud Mirror

Hello, my WD My Cloud Mirror, 3TB each disk (raided) has recently come up saying that it has only 110GB of space left. I have not knowingly added anything on there. I have connected to the folder through file explorer and I can all my stuff which when I run properties on shows it uses about 1.2TB of space.
I don’t run backups or archiving so am confused what is going on and what happened to the space. It is also really sluggish. I have noticed some indexing stuff happening but I have switched off the cloud share stuff to stop this.
Has anyone got an idea where to look?
Many thanks
