Resolution

Run the Script

WARNING: If the recorder is experiencing ongoing hardware issues such as 
unexpected reboots or crashes, do not run the script. Contact support instead.

To run the script:

1. Download the wrnOSspacefixfinal.sh file (attached to this article) and save it to the desktop of your WRN.  
    
2. Unplug all USB sticks and external hard drives.  
    
3. Right-click the desktop of your WRN and open Terminal. 
    
4. Run the following command, then enter your credentials if prompted:
   
   sudo chmod +x /home/wave/Desktop/wrnOSspacefixfinal.sh 
   
   This allows the script to be run as an application. 
    

5. Run the following command, then enter your credentials if prompted:
   
   sudo /home/wave/Desktop/wrnOSspacefixfinal.sh 

   IMPORTANT: The script may take up to 5 minutes to complete. 
   Do NOT perform additional actions during this time.

Reserve the WAVE Drive

Verify the reported Available space is greater than twice the Reserved space size. For example, if the reserve space is set to 2 GB, the available space should be greater than 4 GB.


 

To ensure proper drive configuration:

1. Open the WAVE Client.
    
2. Right-click the location server and select Server Settings.
   
   
    
3. Confirm /opt/Hanwha/mediaserver/var/data is set to Reserved and is NOT set as the drive for Stores analytics and motion data.
   
   
    
4. Open a web browser and navigate to https://ip_address_of_waveserver:7001/, then log in using your credentials.
    
5. In the menu tree on the left, click Servers. 
   
   The URL changes to https://ip_address:7001/#/settings/servers/[server_ID]
   
   
    
6. Add ?advanced= to the end of the URL.
   
   Example: https://ip_address:7001/#/settings/servers/bbcf2bd-af31-ccab-abcd-efg-1234?advanced=
    

7. In the Storage Locations section, change the Reserved space for /opt/Hanwha/mediaserver/var/data to 2GB.
   
   
    

   If the Available space is still less than 4GB, delete the contents of the Downloads and Trash folders using the following commands respectively:

   sudo rm -rf /home/wave/Downloads/*

   sudo rm -rf /home/wave/.local/share/Trash/*

   IMPORTANT: Contact support if the desirable available space cannot be achieved.
