[Pacemaker] Can't failover Master/Slave with group(primitive x3) setting

[Junko IKEDA]

Hi,

I have the following resource setting;

- msDRBD : Master/Slave(drbd)
- grpDRBD : group(including 3 Dummy)

and location setting is here;

location rsc_location-1 msDRBD \
        rule role=master  200: #uname eq bl460g1n13 \
        rule role=master  100: #uname eq bl460g1n14
colocation rsc_colocation-1 inf: grpDRBD msDRBD:Master
order rsc_order-1 0: msDRBD:promote grpDRBD:start


* Initial starting;

Please see the attached hb_report.

I tried to reduce the primitive resource in group from 3 to 2,
and grpDRBD can failover in this case.

If dummy02 or dummy03 break down instead dummy01,
grpDRMD can can failover, too.

Master/Slave and group which has more than 3 resources won't work.
