Most people probably don't keep track of how much disk space the freedom server uses, but our worlds are extremely large, to the point where it will start to affect other customers on our host if they keep growing. To make the size a bit more manageable without destroying everyone's builds, @"Folfy_Blue"#356 has written a script that will delete chunks that do not contain any data. Unfortunately, the worlds are so large that this is not something that can just be done during the off-hours, and not one but three maintenance windows have to be scheduled:
November 27, 2021 at 12:00 UTC:
flatlands (168GB before, 159GB after (stopped prematurely))
December 4, 2021 at 12:00 UTC:
world (123GB before, 51GB after)
December 11, 2021 at 12:00 UTC:
world_nether (23GB before, 8GB after)
world_the_end (22GB before, 6GB after)
adminworld (7GB before, 2GB after)
masterbuilderworld (5GB before, 2GB after)
January 8, 2022 at 12:00 UTC:
flatlands, second attempt (167GB before, 122GB after)
The script has been tested reasonably well, but please look out for missing or corrupted builds in the affected worlds after each maintenance. A full backup of each world will be made right before applying the script.
