Hi - i have a fair few rhel7 pacemaker clusters (running on pacemaker v1) I want to migrate to rhel8 (which uses pacemaker v2) - due to using shared/cluster ip it would be a pain and involve downtime to take down cluster ip on rhel7 cluster then setup on rhel8.
Can I add a pacemaker v2 node to a pacemaker v1 one (in order to migrate easily..) i.e i have these versions rhel7 : pacemaker-1.1.23-1.el7_9.1.x86_64 rhel8: pacemaker-2.1.5-8.el8.x86_64 For the purposes of migrating to rhel8 - could i add a rhel8 (pacemaker v2) node to an existing rhel7 (pacemaker v1.x) cluster If it matters here is the 'supporting' versions of both (using # pacemakerd --features ) rhel7: Supporting v3.0.14: generated-manpages agent-manpages ncurses libqb-logging libqb-ipc systemd nagios corosync-native atomic-attrd acls rhel8 : Supporting v3.16.2: agent-manpages cibsecrets compat-2.0 corosync-ge-2 default-concurrent-fencing default-sbd-sync generated-manpages monotonic nagios ncurses remote systemd If this is not possible I will have to think of another solution. Thanks
