Hello,

we have a two node HA Cluster using
- a large multipathed (SAN) disk on each node
- primary/primary DRBD to mirror these disk
- cLVM, to define a clustered VG
- xen to control VMs
- openais and pacemaker to move the VMs from one node to another

The cluster worked fine with SLES 11 SP2
We upgraded to SP3 and still its working well.
But we get continously this two error messages:
