Overview

While reviewing System Diagnostics, the following System Disk Full alert is triggered:

Full (or almost full) disk partitions: /var

This article provides details on how to resolve the Full disk occupation in /var folder.

Solution

The /var folder contains both statistical monitoring data and diagnostic sysdump crashes.

Once logged in to Exinda CLI, execute:

  en
  _shell

Important: if you're prompted for a License key while running _shell command, you need to Activate the Restricted Commands License, open a Support Ticket and ask them to activate it.

For troubleshooting purposes, you can execute du -x /var | sort -rn | head -20 command. It will display the biggest files/folders.

1. If /var/data/monitor is shown in this list, follow System Disk Full /Var/Data/Monitor instructions.
2. If the command returns a bunch of /var/tmp/sysdump-<Exinda_Hostname> directories, these directories can be safely removed. Execute the following command:

     rm -rf /var/tmp/sysdump*

3. If /var/opt/tms/snapshots is displayed, snapshot files can also occupy a reasonable amount of space. Navigate to /var/opt/tms/snapshots folder (cd command) and execute the identical rm command to delete the files.
4. If /var/opt/tms/stats is displayed, follow /var reaching its Capacity due to /var/opt/tms/stats guide.
5. If /var/log/statisticsd is listed, terminate statisticsd and clear the folder contents:
   

     cli
     en
     pm process statisticsd terminate
     _shell
     rm -rf /var/log/statisticsd/*
     cli
     en
     pm process statisticsd restart

Testing

Execute df -h command to confirm the /var storage has more free space.
