Can we manually reduce the file size of Minecraft SMP server by just deleting .mcr files?

  • Can we manually reduce the file size of Minecraft SMP server by just deleting .mcr files? FatFingeredAdmin

    We had an "accident" with WorldEdit and despite having BoarderGuard installed it sent a tunnel thousands of chunks away. Regardless now the map looks ridiculous. Of course the server crashed during this process and we were robbed of doing a simple /undo!

    The worst part is, we did not notice the problem until a few days later and the several dozen players on our server would be a tad irked if we had to roll back the server a week.

    I have read that deleting chunks etc is totally possible with MCedit. But since we chose to go with Servercraft, dowloading, editing offline, and then trying to reinsert the file back to servercraft is almost a nightmare scenerio. We have Bukkit running, and we are using a mod called BorderGuard so I know exactly what regions we are using. I was just curious if anyone understands what happens when you just delete .mcr files from the /world/region folder? Do they go away permanently?

    I do see that if we were ever to expand the BorderGuard those regions/chunks would come back the same since the seed is the same.

    Anyone manually lop off part of their world and survived?

  • If you can identify exactly which .mcr files you want to delete, you should be able to delete them with no damage done to the rest of the map. Once someone else ventures out there (when you increase the border range), it will simply generate those chunks like they were before, as if it was the first time the chunks were getting generated (using the same seed and all).

  • rent the server from NFOServers and in their control panel, it says "Your server is offline". I click "Start Server" and it says "It appears that the server is already running." Same thing when I click "Restart Server". We are using the Tekkit Main modpack and we have Tekkit.jar selected as the main JAR file. Just as an experiment, I tried the default vanilla JAR file, and that seemed to work fine. We could connect to the server and play and everything, but we couldn't of course see any of the mod pack items. We've tried everything that we can think of but have had no luck. Anyone have

  • I have a Windows server running Team Fortress 2 (TF2) with SteamCMD and I would like to enable auto-updates. For the moment, I have to do it manually with SteamCMD using the app_update command but this is very bad as I must check daily if there are new updates. This is what I've tried : The -autoupdate arg when I launch the game (srcds.exe -autoupdate ...)

  • . However, I was recently trying this with a duo partner, but it didn't actually seem to do anything. Nothing happened when hitting the button (other than the person hitting it got the 'SHARING MISSION: ' popups). It didn't matter if we were right next to each other, who was leader, if we had appropriate empty mission slots, if we then took the mission manually but were on different steps....basically this thing didn't seem to do anything. How do we actually get this working? Is there a restriction we were missing? What's it actually supposed to do?

  • I have minecraft server with a bunch of mods: here the list. The thing is after I explored a big part of world my server began to lag (before that server worked good). When I replaced world with old version of the same world (before exploration and with the same set of mods) lags disappeared. So, I think, I found something in the world that causes lags. How can I find that lagging region and remove the source of lag (kill problem mob, for example, regenerate region)? This is what I get in console when server starts to lag: 16:24:11 [WARNING] The server is going slow. Last server tick
