QRadar: Delete files or directories to gain space in /opt partition

Troubleshooting


Problem

When the root /opt partition in QRadar® SIEM does not have enough space, it can affect the regular functioning of QRadar. The purpose of this article is to help the administrator with the removal of files and directories when the /opt partition has not enough available disk space.

Symptom

Lack of available space in the /opt partition can cause the following issues:
  • Alerts about "Process monitor application failed to start multiple times".
  • Searches reporting I/O errors.
  • Services not starting.
  • Configuration deployment changes due to critical disk space
