Symptoms

  • Backups in PowerFlex Manager are failing.
  • During the backup process, the /var/log location is filled up to 100%.

 

Cause

During PowerFlex Manager backups, the files are stored in a temporary location. This location changed in the 3.8.0.8187 version to a file system that does not have enough space for larger environments.
