[FreeNAS 9 Plugin] - MineOS

[Joshua Parker Ruehlig]

Here is a link to my screenshots. http://imgur.com/a/f4HXG

Looks like something is already bound to port 8080 on the jail. I'd just restart the jail from the Jails tab and try starting mineos from the Plugins tab.

Somehow my server disappeared. I had it active for about 2 months ago, then I moved and didn't start the computer until now. And now I can't find the server at all in the WebGUI. All that I can find now what remains from my server is the file "70876.mc-Craftbukkitserver" which is 0 bits large.

Do you know if I can find the server again and what happened? ;O

that's not a server, that's the screen process.

by default servers are stored in the jail's /var/games/minecraft/servers folder.

Okey, when I look there I don't find the server either. Though I find two old servers in the /maps/servers folder. But my "Craftbukkitserver" is missing completely... :/

did you remember changing the default "base directory" for mineos and/or mount storage into your mineos jail as your "base directory"?

I think I did, but I am not 100% sure...
My base directory in mineos is /var/games/minecraft

so mineos doesn't work anymore? you could check the settings. are you trying to get mineos working again, or copy out your worlds?

MineOS is working just fine, but my World which i named "Craftbukkitserver" is completely missing. I accidently pulled the electricity to the NAS at 2nd of July and as you see in the mineos.log this is the last I've seen of it. :/

"Surfburkentva" and "Craftbukkitserver" were the two servers I had, and now "Craftbukkitserver" is gone after the electricity drop.

since mineos is working, you should be able to know where your servers are. check the mineos settings in the left tab of the freenas webui.

I also noticed a few other errors in the log you posted. did you follow the directions for adding an init command to freenas from the OP? you don't need to do this, but of you dont just make sure to manually start+stop mineos whenever you (re)start freenas.

also you got an rsync error, looks like you're missing librsync.so.1 somehow

Code:

ln -s /usr/pbi/mineos-amd64/lib/librsync.so.1 /usr/local/lib

I've checked everywhere and even made a search on the whole FreeNAS via FileZilla Client through SFTP and didn't find it. It somehow got deleted from the accidental power failure... :/
Yeah, I've used that command before but it didn't bite back then. I have had loads of problem before if you watch page 9 here in this thread for example, lol...

When I use the command below in my jail, it says that the file exists.

Code:

ln -s /usr/pbi/mineos-amd64/lib/librsync.so.1 /usr/local/lib

Mind showing a screenshot of the mineos settings I mentioned? hopefully the server folder still exists =\

My worlds have been running perfectly. I use mineos built in periodic archiving. my 'base directory' is on a storage dataset i snapshot+ replicate. Also got a UPS to tell my server to shutoff if need be.

Yeah, my worlds were running smoothly too until the 2nd of July when I was about to move to another town and accidently pulled the power source.....

I have never completely understood how snapshots and/or replication works. But you seem to have a great working setup! :)

 

[Joshua Parker Ruehlig]

looks like it was left at the default /var/games/minecraft. one last thing you could check would be if you mounted storage to that jail, otherwise I'm out of ideas. somehow your server got deleted =[

would be good to setup archives or snapshots so you could restore incase of issues like this.

Nah, no storage attached to the jail... :/ It got deleted...

Yeah, really! Could you please explain for me (newbie) how it works, or even maybe a guide? Would really help a lot of people I believe. :)

how what works, mineos or zfs snapshots?
for the first one ask on the mineos forums, they know better than I.

Looking to get a little help here.... Not very familiar with FreeNas but been up and running for 3 years on it. This would be my first jail installation other than Plex.

What I am running into is adding Multiple minecraft servers as it seems I can only do one since MineOS only allows the default port so far. I have tried using Iptables commands but it always spits back that is not a recognized command so I am unable to add another port.

Code:

root@mineos_1:/ # iptables --list                                            
iptables: Command not found.                                                 
root@mineos_1:/ #    

FreeNAS-9.3-STABLE-201506292130

Other issue is creating more users for the webui, currently I can only use the default. I want to add another group but cannot figure out where to add them, I can add users in the CLI but I can only add them to the default group...

Also I notice the ram usage is pretty darn high... Like right new HEAP is at 6000/13000 with only 2 people on the server ATM. Java have a leak? Will this lower with a server reboot?

Sorry lots of nub questions here not very experience with linux



So end goal...
1.be able to create multiple Minecraft servers in Webui ( I Can handle the port forwarding just need to enable the extra ports)
2. Add a new group other than Mcserver and add users to that group to manage the servers / different servers.

1) you can change the port a minecraft server runs on. it's in the server.properties page.

2) this is all done in the jail's commandine. user group management is covered in the freebsd handbook. if you read the opening post of this thread I explain what I know about server permissions in mineos.

I've seen numbers memory usage higher than 6GB before. as users explore more areas more is loaded into ram until it reaches the max you allowed it. then java will start kicking stuff from memory. as the server runs longer ram usage will keep increasing, which is what you want it to do, you gave it a 13GB limit.

Thank you for the quick response, apparently you have the magic touch as before any server I created on a different port would not start and now it just decided to do so.

I will read into the handbook more for users and see if I can get it working.

Did not know that is how the memory worked, I will just lower what the server has access to then. Any idea on what amount of RAM is recommended for most servers? These would be maybe 15 players max at once.

not sure. I keep mine around 8GB but I'm just guessing.

ZFS snapshots and/or replication
