Alert PEGA0085 - Disk space Issue



PEGA0085 alert is logged in the Alert log.

Decision Data Store (DDS) nodes have 20GB - 32GB local disk space and 3TB for Cassandra on a network storage.

Several DDS or Cassandra nodes are present with several data storages mounted per node.

For the Cassandra table space, the user foresaw more than 1TB. However, when viewing the DDS node properties, they only have a couple of GBs.
Therefore the requirement is to know which device Pega incorrectly refers to and how to make the application refer to the correct hard drive.

Steps to Reproduce

Not Applicable

Root Cause

A hardcoded path was taken to calculate the already used and still available diskspace. When a different location for the respective files was configured, it was not considered.


Apply HFix-45958.
