Ok. It seems that advisory working is not working with normal
resources either... So I tried the following configuration:

I'm expecting for p_fs_nfs_config_nocmc1 and p_fs_nfs_other_nocmc1 to
be started after p_exportfs_config, p_exportfs_other_lower
respectively, but this doesn't happen. p_fs_nfs_config_nocmc1 and
p_fs_nfs_other_nocmc1 get started right when pacemaker starts, along
with p_ip_nfs, the first resource to get started. Here is an extract
from /var/log/messages:
