Can I update software packages on a RHEL High Availability or Resilient Storage node while it is an active member of the cluster?
Issue
- I updated my cluster software while the node was still a member and the cluster became unstable
- A node had its software updated while it was live and resources began behaving strangely or giving errors
- Nodes crashed or were fenced while having their RPMs updated with
yum - Do I need to stop the cluster daemons on my nodes before I update packages?
Environment
- Red Hat Enterprise Linux (RHEL) 5, 6, 7, 8 or 9 with the High Availability or Resilient Storage Add-On
