Sorry, didn't read careful enough, was distracted by the actions
in the description. Yes, you need both the order and the
collocation.
Basically what I want to achieve is the same behaviour of an
unordered group of heartbeat 2.1.4.
Why don't you keep the unordered group?
Uhm, in heartbeat 2.1.4 i could specify "collocated=true/false" and
"ordered="true/false" for the groups. As I said I nedd an unordered,
collocated group.
In pacemaker I didn't find a way to specify this options for group (through
the gui or the cli). According to the docs:
Use a resource set:
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/s-resource-sets-collocation.html
So if I don't get the docs wrong this:
<constraints>
<rsc_order id="order-srvha01" score="INFINITY">
<resource_set id="order-rs-drbd1" role="Master">
<resource_ref id="ms-drbd1"/>
</resource_set>
<resource_set id="order-rs-fs1">
<resource_ref id="fs-datastore1"/>
</resource_set>
<resource_set id="order-rs-vm1" sequential="false">
<resource_ref id="w2003R2-1"/>
<resource_ref id="w2003R2-3"/>
<resource_ref id="openfiler"/>
</resource_set>
</rsc_order>
<rsc_colocation id="colo-srvha01" score="INFINITY" >
<resource_set id="colo-rs-vm1" sequential="false" role="Started">
<resource_ref id="w2003R2-1"/>
<resource_ref id="w2003R2-3"/>
<resource_ref id="openfiler"/>
</resource_set>
<resource_set id="colo-rs-fs1" role="Started">
<resource_ref id="fs-datastore1"/>
</resource_set>
<resource_set id="colo-rs-drbd1" role="Master">
<resource_ref id="ms-drbd1"/>
</resource_set>
</rsc_colocation>
</constraints>
should do the trick and:
promote drbd1 on srvha01, start fs-datastore1 on srvha01, start virtual
machines on srvha2 (in any order). Right?
I don't get why resources should be placed in reverse order in
colocations anyway.
It seems to work fine but still:
[r...@srvha01 ~]# crm configure show
ERROR: object colo-srvha01 cannot be represented in the CLI notation
ERROR: object order-srvha01 cannot be represented in the CLI notation
