I did more tests to find the cause of the problem.
I found that clustat has problem with "restricted" failover domain.
I tested 2 examples of my configuration:
1. failover domain is "restricted"
<rm>
<failoverdomains>
<failoverdomain name="VM_w1_failover" ordered="0" restricted="1">
<failoverdomainnode name="w1.local" priority="1"/>
</failoverdomain>
<failoverdomain name="VM_w2_failover" ordered="0" restricted="1">
<failoverdomainnode name="w2.local" priority="1"/>
</failoverdomain>
</failoverdomains>
<resources/>
<vm autostart="1" domain="VM_w1_failover" exclusive="0"
name="VM_Work11_RHEL51" path="/virts/w11" recovery="restart"/>
<vm autostart="1" domain="VM_w1_failover" exclusive="0"
name="VM_Work12_RHEL51" path="/virts/w12" recovery="restart"/>
<vm autostart="0" domain="VM_w1_failover" exclusive="0"
name="VM_Work13_RHEL51" path="/virts/w13" recovery="disable"/>
<vm autostart="1" domain="VM_w2_failover" exclusive="0"
name="VM_Work21_RHEL51" path="/virts/w21" recovery="restart"/>
<vm autostart="0" domain="VM_w2_failover" exclusive="0"
name="VM_Work22_RHEL51" path="/virts/w22" recovery="disable"/>
<vm autostart="0" domain="VM_w2_failover" exclusive="0"
name="VM_Work23_RHEL51" path="/virts/w23" recovery="disable"/>
</rm>

After power off node w2.local and fencing "w2.local" by "w1.local"
clustat still shows the service vm:VM_Work21_RHEL51 is started on
w2.local

vm:VM_Work21_RHEL51 w2.local.polska.pl started
vm:VM_Work22_RHEL51 (none) disabled
vm:VM_Work23_RHEL51 (none) disabled
2. failover domain is not restreicted
<failoverdomains>
<failoverdomain name="VM_w1_failover" ordered="0" restricted="0">
<failoverdomainnode name="w1.local" priority="1"/>
</failoverdomain>
<failoverdomain name="VM_w2_failover" ordered="0" restricted="0">
<failoverdomainnode name="w2.local" priority="1"/>
</failoverdomain>
</failoverdomains>
Clustat before shutting down w2.local:
[root@w1 ~]# clustat
Member Status: Quorate
Member Name ID Status
------ ---- ---- ------
w2.local.polska.pl 1 Online
w1.local.polska.pl 2 Online, Local, rgmanager
Service Name Owner (Last) State
------- ---- ----- ------ -----
vm:VM_Work11_RHEL51 w1.local.polska.pl started
vm:VM_Work12_RHEL51 w1.local.polska.pl started
vm:VM_Work13_RHEL51 (none) disabled
vm:VM_Work21_RHEL51 w2.local.polska.pl started
vm:VM_Work22_RHEL51 (none) disabled
vm:VM_Work23_RHEL51 (none) disabled
After shutting down w2.local rgmanager migrate service
vm:VM_Work21_RHEL51 to w1.local and clustat shows correct states.
[root@w1 ~]# clustat
Member Status: Quorate
Member Name ID Status
------ ---- ---- ------
w2.local.polska.pl 1 Offline
w1.local.polska.pl 2 Online, Local, rgmanager
Service Name Owner (Last) State
------- ---- ----- ------ -----
vm:VM_Work11_RHEL51 w1.local.polska.pl started
vm:VM_Work12_RHEL51 w1.local.polska.pl started
vm:VM_Work13_RHEL51 (none) disabled
vm:VM_Work21_RHEL51 w1.local.polska.pl started
vm:VM_Work22_RHEL51 (none) disabled
vm:VM_Work23_RHEL51 (none) disabled
I'm not sure but I think there is something wrong with rgmanager/clustat
wnen services are configured with restricted failover domain.
