Limit Service's Disk Space

Configure disk quotas in your drive

Linux

• Follow these instructions to configure disk quotas on Linux: Linux_Quotas

Windows

• Enable quotas on the drive where the services will be created. The configuration shown in the screenshot is recommended.

Configure the game

• Configure the game with Run As = User per Service. Go to Settings > Games > select the game > Select the "Run As" tab. Set Run As = User per service and save. This will create one Windows/Linux user for each service. The disk quota will be created for this user.

If you have existing services of this type go to Settings > Game Tools and run the Verify/Repair tool on your server with "Update run as user" checked.

• Configure a variable for the quota value. Click on the Variables icon. Click on new and enter these values:
  • Name: DiskQuota
  • Default value: 0
  • Is numeric: Checked
  • Preserve value: Checked
• Select the Variable Options tab and configure these values:
  • Script parameter: Checked
  • Save script parameter value: Checked
  • Admin access: Checked
  • Value is required: Checked
  • Item Type: Numeric textbox
  • Label: Disk Quota (MB)
  • Description: Specify the disk quota in MB. Set to 0 for unlimited space.
  • Decimal Digits: 0

• Configure the scripts. Go back to the game's main settings. Click on the Custom Scripts icon. Configure the following scripts.

from System import UInt64, String, Exception;

diskquotamb = ThisService.Variables["DiskQuota"];
serviceuser = ThisService.GetServiceCredentials().User;
mountpoint = ThisServer.FileSystemService.GetMountPoint(ThisService.RootDirectory);

if not ThisServer.FileSystemService.QuotasEnabled(ThisService.RootDirectory) :
 raise Exception(String.Format("Disk quotas are not enabled on {0}", mountpoint));

Script.WriteToConsole(String.Format("Creating {0}MB disk quota on {1} for {2}", diskquotamb, mountpoint, serviceuser));

ThisServer.FileSystemService.SetQuota(serviceuser, mountpoint, UInt64.Parse(diskquotamb) * 1024 * 1024);

Operating System: Any

Script Engine: IronPython
Event: Before deleted
Script:

import clr;

mountpoint = ThisServer.FileSystemService.GetMountPoint(ThisService.RootDirectory);

if not ThisServer.FileSystemService.QuotasEnabled(ThisService.RootDirectory) :
raise Exception(String.Format("Disk quotas are not enabled on {0}", mountpoint));

Script.WriteToConsole(String.Format("Deleting disk quota on {0} for {1}", mountpoint, serviceuser));

ThisServer.FileSystemService.SetQuota(serviceuser, mountpoint, 0);
