Introduction
This guide offers Red Hat's policies, requirements, and limitations applicable to the use of Google Cloud Platform virtual machines as members of a RHEL High Availability cluster. Users of RHEL High Availability software components should adhere to these policies by installing only on the approved platforms in order to be eligible to receive assistance from Red Hat Support with the appropriate support subscriptions.
Policies
Consider general conditions for support of RHEL High Availability in virtualization environments
Supported releases for Google Cloud Platform virtual machines as High Availability members: Red Hat supports RHEL High Availability cluster members running on Google Cloud Platform virtual machines with the following RHEL releases or later:
- RHEL 8: Supported by Red Hat
- RHEL 7: Supported by Red Hat with RHEL 7.6 or later - using packages
pacemaker-1.1.19-8.el7
,corosync-2.4.3-4.el7
,fence-agents-*-4.2.1-11.el7
or later.
Supported transport protocols: RHEL 7 High Availability clusters with members that run on Google Cloud Platform can only use the udpu
transport protocol - which is the default in RHEL 7 clusters. Google Cloud VPC networks do not support multicast traffic, preventing the usage of the udp
transport protocol.
Red Hat only supports the knet
transport in RHEL 8, regardless of platform.
