Ciao,I am still setting the HA configurazion, we have 2 node cluster in active/passive mode.
- to check the SAN storage device we use an external stonith device and in case of SAN's failure on the active machine, it should do a shutdown instead it makes a reboot.
In the cluster property section of the cib.xml I have<nvpair id="cib-bootstrap-options-stonith-enabled" name="stonith- enabled" value="true"/> <nvpair name="stonith-action" id="cib-bootstrap-options- stonith-action" value="poweroff"/>
- regarding the "failback OFF" In the cluster property section of the cib.xml file I have<nvpair name="default-resource-stickiness" id="cib- bootstrap-options-default-resource-stickiness" value="INFINITY"/> <nvpair id="cib-bootstrap-options-default-resource-failure- stickiness" name="default-resource-failure-stickiness" value="0"/>
The failback is working , when the active node is coming back the resource still remains on the passive node , for migrating the resource
I have to execute the following commandcrm_resource -M -H <active_node> -r <group> -f (it doesn't migrate without -f )
crm_resource -U -H <passive_node>
If I repeat the exercise: simulate failure on the active node a couple
of times it happens that the passive_node don't take the resource.
In attachment you will find the ouput of cibadmin -Q Thanks in advance for any help cristina
