[Pacemaker] crm_mon/pacemaker split brain

[Raoul Bhatia [IPAX]]

hi,

crm_mon shows me a kind of split-brain view of my cluster:

common lines on my two nodes:

> Node: wc02 (f36760d8-d84a-46b2-b452-4c8cac8b3396): online
> ...

wc01's view:
> Clone Set: clone_nfs-common
>     Resource Group: group_nfs-common:0
>         nfs-common:0    (lsb:nfs-common):       Started wc01
>     Resource Group: group_nfs-common:1
>         nfs-common:1    (lsb:nfs-common) Started [      wc01    wc02 ]

wc02's view:
> Clone Set: clone_nfs-common
>     Resource Group: group_nfs-common:0
>         nfs-common:0    (lsb:nfs-common) Started [      wc01    wc02 ]
>     Resource Group: group_nfs-common:1
>         nfs-common:1    (lsb:nfs-common):       Started wc01

the information basically is the same, but the two instances of the
clone "group_nfs-common:0" and "group_nfs-common:1" are swapped.

the configuration is:
wc01: pacemaker 1.0.1; heartbeat 2.99.2
wc02: pacemaker 1.0.0; heartbeat 2.99.1
