Aug 10 15:51:25 kvm08 drbdmanaged[1756]: INFO updating storage
pool information
As to what the box is doing at the time - running the VM one01 and a
DRBDManage cluster with no resources in it.
one01 is an OpenNeubula frontend and both kvm08 and kvm12 are OpenNebula
nodes. OpenNebula has no VMs and only the default datastores configured
and is basically doing nothing at this point.
Hope that that helps. Let me know if there is anything else.
