For Linux deployments, the Web Help Desk service or PostgreSQL service will require buffer space on the server drive before it starts properly. There will be instances where the Web Help Desk service or the PostgreSQL service will fail to start if there are no available disk space in the server.

Files or folders below are using the main drive space

• /usr/local/webhelpdesk/pgsql9/Backups
• /usr/local/webhelpdesk/bin/tomcat/logs/catalina.out
• /usr/local/webhelpdesk/installerbackup/

1. Log in to the Linux appliance server as root
2. To confirm if the disk space is full, run the command below:

Here are the folders to check.

• /usr/local/webhelpdesk/pgsql9/Backups
• /usr/local/webhelpdesk/bin/tomcat/logs/catalina.out
• /usr/local/webhelpdesk/installerbackup/

Once the problem folder or file is identified, follow the steps below.
