Prior the ls114 version, the RRD files have a size of 2986708, from ls114 the size is 2986716

Workaround

Stop and remove the smokeping container. Rename the data folder to data.old Create a new smokeping container with the latest image Start the new container This will create new rrd files (no history) with the correct size.

Recommended fix

Convert the old RRD files to the new format
