I found out that this was related to the translog, which was occupying a lot of disk space.

I followed the reccommendations on this link:

> [@Large translog files using 6.0 stack](https://discuss.elastic.co/t/large-translog-files-using-6-0-stack/110375/6):
>
> For a single node cluster they will not be very useful.

I set my maximum retention size to 50mb and my maximum retention age to 60m. This made the translog size to decrease from almost 30gb to 2.5gb

Thanks a lot
