Problem

If you extend the filesystem at the Checkmk Appliance without leaving a little space at the end of the partition, you will receive an error message on the cluster page: 

Screenshot of the appliance clustering page with a notice of Your device can not be used for clustering, because the data volume has a non compatible format. To fix this, you need to reinitialize your data volume by restoring the factory settings via the console.

Please note: You will need to manually back up / restore your data to prevent losing this information.
