Issue/Introduction

Upgrading a server to 10.4.1 and I get a message that there is not enough disk space. There is plenty of space in the directory where it's being installed.
/dev/mapper/apvg01-ap1000                                                  75G   26G   50G  35% /opt/CA

Environment

Release : 10.4.1

Component : Spectrum Core / SpectroSERVER

Resolution

SRAdmin requires space on root "/" partition as well.

Clear enough space on this partition and the install will succeed.
