Issue:

 

 

The following characterizes the issue seen when attempting to login to the NMC:   

      - You can reach the NMC server through a web browser and download the gconsole.jnlp.     
      - You are prompted to login, but when entering your credentials receive:     
      "Error: There is a problem contacting the server, <nmc_server_hostname>. Please verify that the server is running."     
      - The NMC server's GST service is running.   
                                                             

 

 

Cause:

 

 

The partition NMC is installed on has reached 100% capacity which will corrupt the NMC database. This can be identified in the NMC server's gstd.raw:   

      Linux: /opt/lgtonmc/logs/gstd.raw     
      Windows: [NMC Installation Path]\Management\GST\logs\gstd.raw     
      Note: Replace NMC Installation Path with the full path including drive letter for your NMC installation.   
   
     
      You can render this log by opening a command prompt to the NMC logs directory and running: nsr_render_log gstd.raw > gstd.txt     
      Note: If a capacity issue is suspected, redirect the output gstd.txt to another location with more available space.     
     
      The log will contain:   
   
      MM/DD/YYYY HH:MM:SS 1 5 0 1444923136 31877 0 nmc_server_hostname gstd NSR notice MM/DD/YY HH:MM:SS Emergency: Filesystem for /opt/lgtonmc/lgto_gstdb is 100.0% full, with 000000 kB avail.        
        MM/DD/YYYY HH:MM:SS 1 5 0 1444923136 31877 0 nmc_server_hostname gstd NSR notice MM/DD/YY HH:MM:SS Emergency: Filesystem for /opt/lgtonmc/logs is 100.0% full, with 000000 kB avail.
   
                                                             

 

 

Resolution:

 

 

There are two available options:   
   
    (1) Recover:    

      - Reclaim/increase space on the NMC partition.     
      - Perform recoverpsm.     
      - See KB 502728 and/or the NetWorker Command Reference Guide for detailed usage of recoverpsm.   
   
     
      (2) Reinstall:   
   
      - If there are no backups of the NMC or a recovery is not possible then the only option is to reinstall the NMC software.     
      Note: This will not remove your NetWorker server configuration, only the NMC database (users, reports, etc.) will be removed.     
      - Reclaim/increase space on the NMC partition.     
      - Uninstall the NMC software     
      Note: this will not automatically remove the NMC database/log files.     
      - Move the existing NMC installation directory to another location with more space.     
      - Reinstall the NMC software.     
      - If previously configured, reconfigure NetWorker User accounts and/or LDAP AD integration.
