MineOS crash on Fresh install 11.2-u5

[blueberryjr]

The mineos software will crash after creating a new server in the webui. I've tried searching for answers using the log output but can't find any fixes. Any help is appreciated. Running threadripper 2920x 64gb ram gb x399 aorus pro mobo

Hmmm... there are some similar reports, but not much to go on.

• What is crashing... is it mineos itself, or the new server you are creating? What is doing when you say "crashing"?
• What profile are you using? Is is consistently "crashing" when you create any new server for any profile?
• Do older/existing minecraft servers still run fine?
• Did you install the MineOS plugin from the FreeNAS Gui 11.2-u5, or was the plugin installed using an older release?

Can you provide the output of the following commands, run from within your mineos jail:

Code:

pkg -vv | grep url
freebsd-version
java -version
node --version
npm --version

 

[blueberryjr]

No server gets created, the UI crashes, not sure if the mineos server also crashes as well.\
It crashes under every profile.
Fresh install, no servers
Installed from the plugin in freenas 11.2-u5

Code:

pkg -vv | grep url

[Jurgen Segaert]

I have the same versions, yet all works fine.
Can you try to rebuild the plugin... run the following from the FreeNAS command line:

Code:

iocage stop mineos
iocage update mineos

This will reinstall the plugin, but preserve all your servers.

 

[blueberryjr]

Ran update, still crashes immediately after creating server

 

[Jurgen Segaert]

From the Traceback you posted earlier, I suspect something going on with mounting linprocfs.
What's the output of ll /compat/linux/proc/ inside your jail?

 

[blueberryjr]

It doesn't seem to exist. Getting:

Code:

 /compat/linux/proc/: No such file or directory

 

[Jurgen Segaert]

That's a problem. :)

Can you check if/where it's mounted? Make sure your mineos jail is running and from your FreeNAS host, run the following:

Code:

mount | grep linprocfs

and
iocage get mount_linprocfs mineos

Code:

iocage get mount_linprocfs mineos

The latter should return '1'. Also if you have an opportunity, you may want to try rebooting your FreeNAS host.

 

[blueberryjr]

mount | grep linprocfs returns a blank result

iocage get mount_linprocfs mineos returns with 0

Should I run the linprocfs portion of this guide here?

 

[Jurgen Segaert]

You can just stop your jails and set the flag to '1' via the command line:

Code:

iocage stop mineos
iocage set mount_linprocfs=1 mineos

... or just check the checkbox in the FreeNAS UI under jails>Edit>Custom Properties

I assume when you created the jails, you used the "Advanced properties"? I think the bug is that the GUI doesn't respect the default properties from the plugin script. I'll do some more testing and log a defect.

 

[blueberryjr]

Thanks that fixed it.
I'm pretty sure I created the jail with basic setup. I installed a second just to be sure and all of the proper settings were enabled.

 

[Jurgen Segaert]

Great to hear this is fixed and thank you for your help to identify the root cause!
