Cause

Insufficient allocated disk space

pg-data-clamp pvc had been manually reconfigured and reduced from 1GB to 300MB and only 34Mb was available.

Environment

DX Platform 2x

Resolution

Increase capacity to the pg-data-clamp PVC

As per documentation: https://techdocs.broadcom.com/us/en/ca-enterprise-software/it-operations-management/dx-platform-on-premise/21-3/installing/Hardware-software-requirements.html

Starting from 21.3.x, the min requirement is 50GB

 

NOTE: 

If you are using DX Platform 20.2.1, do not change the default allocated capacity as DSP functionality (dsp_db) requires a lot of space.  dsp db is no longer used in 21.3 or later versions.
