What’s the right way to stop/ start cluster:
As per RH, we can bring down cluster services in reverse order BUT service group might failover to 2nd node which I think can be stop by freezing cluster (please correct me if I am wrong)
service rgmanager stop
, if you using high-availability (HA) services (rgmanager
).service gfs2 stop
, if you are using Red Hat GFS2umount -at gfs2
, if you are using Red Hat GFS2 in conjunction withrgmanager
, to ensure that any GFS2 files mounted duringrgmanager
startup (but not unmounted during shutdown) were also unmounted.service clvmd stop
, if CLVM has been used to create clustered volumesservice cman stop
OR can I simply stop by running “clusvcadm -s servicegroup” on both nodes (A&B) & restarts with “clusvcadm -e servicegroup -m nodename”.
Appreciate if anyone share their experience or best practice.
Thanks
