 **Background**
 
 If disk usage is 95% or more, elasticsearch goes into read-only mode, and creating new datapoints is not possible any more. To remove old content from the database, it is first necessary to create some free space on the disk (since the database needs space to perform deletetion-operations), then unlock the database, and then remove unnecessary old content from it.
