[ClusterLabs] pacemaker fencing

[Papastavros Vaggelis]

Dear friends ,

I have two_nodes (sgw-01 and sgw-02) HA cluster integrated with two APC
PDUs as fence devices

1) pcs stonith create node2-psu fence_apc ipaddr="10.158.0.162" login="apc"
passwd="apc" port="1" pcmk_host_list="sgw-02" pcmk_host_check="static-list"
action="reboot" power_wait="5" op   monitor interval="60s"
pcs constraint location node2-psu prefers sgw-01=INFINITY


2)pcs stonith create node1-psu fence_apc ipaddr="10.158.0.161" login="apc"
passwd="apc" port="1" pcmk_host_list="sgw-01" pcmk_host_check="static-list"
action="reboot" power_wait="5" op monitor interval="60s"
pcs constraint location node1-psu prefers sgw-02=INFINITY


Fencing is working fine but i want to deploy the following scenario :

If one node fenced more than x times during a specified time period then
change the fence action from reboot to stop.

For example if the node rebooted more than 3 times during one hour then at
the next crash change the fence action from reboot to off.

Is there a proper way to implement the above scenario  ?

is it mandatory to use two level fencing  for the above case ?



Sincerely
