Concern with installation of GPDB High Availability Service

Products

• VMware Tanzu Data Suite

Issue/Introduction

When running the High Availability (HA) feature we found that when there was no active gpadmin session, which keeps the postmaster service in the user context alive. We found that when you are not logged in as gpadmin, the HA service does not run. 

Resolution

Verify that linger is enabled for the gpadmin user on the server:

loginctl show-user gpadmin | grep Linger

Linger=yes

If not, run this on EVERY node (coordinator & all segments) as root:

sudo loginctl enable-linger gpadmin
