Hi, All!
I have a Logical Cluster where a set of servers running different server
applications provide complex set of services.
To make the explanation short a have 8 custom application groups each within a
pool of several nodes.
I was thinking that it would be ok if I install my applications each in its own
pool of nodes and define "lsb" resources of the type bellow then create
location restrictions and have one "gigantic" cluster manage all of them...
An example would be resource:
<primitive class="lsb" id="pprus" type="pprus">
<operations>
<op id="pprus-0-monitor-10s" interval="10s" name="monitor"
timeout="90s"/>
<op id="pprus-0-start-0" interval="0" name="start" timeout="25s"/>
<op id="pprus-0-stop-0" interval="0" name="stop" timeout="25s"/>
</operations>
</primitive>
With restriction to run only on the two nodes where it is installed:
<rsc_location id="dont-run-pprus-unless-ppst1pru01" rsc="pprus">
<rule id="dont-run-pprus-rule" score="-INFINITY" boolean-op="or">
<expression id="dont-run-pprus-expr-0" attribute="#uname" operation="ne"
value="ppst1pru01"/>
<expression id="dont-run-pprus-expr-1" attribute="#uname" operation="ne"
value="ppst1pru001"/>
</rule>
</rsc_location>
However what probably happens is that the cluster software somehow
touches/monitors nodes with score="INFINITY" too because what I get after
#crm resource cleanup pprus
is:
Failed actions:
pprus_monitor_0 (node=ppst1mlb001.ppst3.intra, call=135, rc=254,
status=complete): <unknown>
pprus_monitor_0 (node=ppst1mlb101, call=144, rc=254, status=complete):
<unknown>
pprus_stop_0 (node=ppst1mlb101, call=145, rc=254, status=complete):
<unknown>
pprus_monitor_0 (node=ppst1pbf101, call=150, rc=254, status=complete):
<unknown>
pprus_stop_0 (node=ppst1pbf101, call=151, rc=254, status=complete):
<unknown>
pprus_monitor_0 (node=ppst1pbf001, call=195, rc=254, status=complete):
<unknown>
pprus_stop_0 (node=ppst1pbf001, call=196, rc=254, status=complete):
<unknown>
Even more interesting is that when I check:
#crm resource status pprus
resource pprus is running on: ppst1mlb001.ppst3.intra
resource pprus is running on: ppst1mlb101
resource pprus is running on: ppst1pbf101
resource pprus is running on: ppst1pbf001
But this is absolutely not possible as the application and its LSB script are
not even installed on any of the listed nodes!
Please, help!
What am I missing in the concept?
Thanks!
