Hello!
I am working on a cluster with a two Master/Slave instances.
I have: 2 drbd Master/Slave instance, 1 pingd clone instance, 1 group
with Filesystem resource.
ms-drbd0 is the first Master/Slave
ms-drbd1 is the second Master/Slave
mail_Group is the first group, it depends on ms-drbd0
samba_Group is the second group, it depends on ms-drbd1
I have the next rules:
<rsc_order id="mail-drbd0_before_fs0" from="Montaxe_mail"
action="start" to="ms-drbd0" to_action="promote"/>
<rsc_order id="samba-drbd1_before_fs0" from="Montaxe_samba"
action="start" to="ms-drbd1" to_action="promote"/>
(starts Montaxe_mail when ms-drbd0 has been promoted, start
Montaxe_samba when ms-drbd1 has been promoted. These rules are ok, I
think)
<rsc_colocation id="mail_Group_on_ms-drbd0" to="ms-drbd0"
to_role="master" from="mail_Group" score="INFINITY"/>
<rsc_colocation id="samba_Group_on_ms-drbd1" to="ms-drbd1"
to_role="master" from="samba_Group" score="INFINITY"/>
(Run mail_Group only on the master node, run samba_Group on the master
node)
<rsc_location id="mail:drbd" rsc="ms-drbd0">
<rule id="rule:ms-drbd0" role="master" score="100">
<expression attribute="#uname" operation="eq"
value="debianquagga2"/>
</rule>
<rule id="mail_Group:pingd:rule" score="-INFINITY" boolean_op="or">
<expression id="mail_Group:pingd:expr:undefined"
attribute="pingd" operation="not_defined"/>
<expression id="mail_Group:pingd:expr:zero" attribute="pingd"
operation="lte" value="0"/>
</rule>
</rsc_location>
<rsc_location id="samba:drbd" rsc="ms-drbd1">
<rule id="rule:ms-drbd1" role="master" score="100">
<expression attribute="#uname" operation="eq"
value="debianquagga2"/>
</rule>
<rule id="samba_Group:pingd:rule" score="-INFINITY" boolean_op="or">
<expression id="samba_Group:pingd:expr:undefined"
attribute="pingd" operation="not_defined"/>
<expression id="samba_Group:pingd:expr:zero" attribute="pingd"
operation="lte" value="0"/>
</rule>
</rsc_location>
(Select debianquagga2 as Master and if the node lost its connection
take the score -INFINITY to do failover, it applies to ms-drbd0 and
ms-drbd1)
With this rules all is working very well but the node selected as
master isn't "debianquagga2", Why could be the reason ?
I using Heartbeat 2.1.4
I have attached the cib xml file. If I delete two groups, Master is
debianQuagga2, If not, Master is debianQuagga1.
