Recently, I encountered a ticket where the customer faced difficulties writing to the var directory. In this article, we’ll explore how I resolved this issue:
- Begin by logging into the ESXi host via SSH and executing the following command:
vdf -h- Next, examine the output of the command mentioned above to determine if the available space is full or not.
- If the space appears to be full in the /var directory, navigate to /var using this command:
cd /var- Once within the /var directory, execute the following command. This will display the sizes of all folders and files within the /var directory:
du -shc *- Identifying that /var/spool is the directory causing the issue, I proceed to navigate to it:
cd /var/spool- Upon inspection, I found numerous trap files, which likely resulted from errors in the host.
Having identified the root of the problem, let’s delve into the solution:
- To disable SNMP, enter the following command:
esxcli system snmp set -e false- Subsequently, delete all contents of the /var/spool directory using this command:
rm *.trap
With these steps completed, the space issue within the /var directory should be resolved, allowing normal write operations.

Conclusion
In conclusion, resolving the full storage issue in the ESXi host’s /var/spool directory is essential for optimal performance. By investigating the root cause, disabling SNMP, and removing unnecessary files, we’ve successfully addressed the problem.
