"Cordoba": df is lying (or is it du?)

Scenario: "Cordoba": df is lying (or is it du?)

Level: Medium

Type: Fix

Tags: bash  

Access: Email

Description: Monitoring reports that the root filesystem is under pressure, but a quick du of /var/log shows almost nothing in the logs of the running application at /var/log/cordoba-app.

Find what is holding the space and reclaim it so df and du agree again for practical purposes; currently there's a ~300 MB discrepancy on the root partition /

The service unit is cordoba-hoarder.service.

Root (sudo) Access: True

Test: df -h / and sudo du -sh / report the same used space after reclaiming the ~300 MB discrepancy.

The "Check My Solution" button runs the script /home/admin/agent/check.sh, which you can see and execute.

Time to Solve: 10 minutes.
