Andrew,
Thanks for your reply. Please refer to <--'s below.
The resulting behavior is that the app only restarts on the same node,
never ping-pong.
**************************************************************
i assume "ON" and "OFF" refer to the resource state? <--YES YOU ARE
RIGHT
try:
rsc_location(your_resource, BOX1, 10000) rsc_location(your_resource,
BOX2, 10000) default_resource_failure_stickiness = 100
default_resource_stickiness = 10
that should let it ping-pong (due to failures) between your nodes 200
times before we'll give up
<--- YES ping-pong in response to successive app failures is exactly
what I'm after. See mods below:
I CHANGED STICKINESS VALUES:
<nvpair id="cib-bootstrap-options-default_resource_stickiness"
name="default_resource_stickiness" value="10"/>
<nvpair id="cib-bootstrap-options-default_resource_failure_stickiness"
name="default_resource_failure_stickiness" value="100"/>
I ADDED rsc_location CONSTRAINTS <-- DID I DO THIS RIGHT?????????
no, you only specified scores for one node
<------- QUESTION #1
IS IS OK TO APPLY rsc_location with rsc_colocation CONSTRAINTS
<------- QUESTION #2
ANY IDEAS WHY I'M NOT GETTING ONLY GETTING RESTART BEHAVIOR AND NOT
PING-PONG BEHAVIOR <------- QUESTION #3
