No Service Outage Server Maintenance
------------------------------------
Should you need perform maintenance on the kerberos server that requires
taking kerberos processes offline you can do this by performing your
updates on a single server at a time.
`kdc01.openstack.org` is our primary server and `kdc02.openstack.org`
is the hot standby. Perform your maintenance on `kdc02.openstack.org`
first. Then once that is done we can prepare for taking down the
primary. On `kdc01.openstack.org` run::
root@kdc01:~# /usr/local/bin/run-kprop.sh
You should see::
Database propagation to kdc02.openstack.org: SUCCEEDED
Once this is done the standby server is ready and we can take kdc01
offline. When kdc01 is back online rerun `run-kprop.sh` to ensure
everything is working again.
