another thing i noticed with this cib:

crm_mon still did not show the full configuration but had two errors,
both related to wc02, at the bottom.

i installed the new debian packages, which lead to an automatic
heartbeat shutdown (which hang). i then issued:
> crm_resource -C -H wc02 -r extip_ftp
> crm_resource -C -H wc02 -r stonith_rackpdu:1 

and the shtudown finished, and "all of a sudden" i saw all resources
including it's status when issuing crm_mon -1 on wc01.

any ideas?

cheers,
raoul
