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

Troubleshooting


Problem

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

Symptom

Lack of free space in the "/" 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.
