Hi,
we have a cluster with 2 nodes with heartbeat 2.1.2 and Red Hat Linux
after setting one node to standby, stopping heartbeat on it,
uninstalling heatbeat, removing all heartbeat directories and
installing heartbeat again, configuration detect two nodes with the
same name but different id:
Node: polonio (296f7c6c-9698-40f1-af8e-5d4917318701): OFFLINE
Node: einstenio (30b5f04e-b6bd-4c89-ab79-629590a0e7ae): online
Node: polonio (40eaf81e-ac04-4099-bea7-99d84ea10d0d): online
node section in cib.xml is
<nodes>
<node uname="polonio" type="normal" id="296f7c6c-9698-40f1-
af8e-5d4917318701">
<instance_attributes id="nodes-296f7c6c-9698-40f1-
af8e-5d4917318701">
<attributes>
<nvpair name="standby" id="standby-296f7c6c-9698-40f1-
af8e-5d4917318701" value="off"/>
</attributes>
</instance_attributes>
</node>
<node id="30b5f04e-b6bd-4c89-ab79-629590a0e7ae"
uname="einstenio" type="normal"/>
<node id="40eaf81e-ac04-4099-bea7-99d84ea10d0d" uname="polonio"
type="normal"/>
</nodes>
Is there a safe way to remove unused node?
the easiest way is to shutdown the entire cluster and remove the
hostcache file from each one
then do:
cibadmin --cib_delete --obj_type nodes --crm_xml ‘<node
id=”296f7c6c-9698-40f1-af8e-5d4917318701”/>’_______________________________________________
