[Linux-HA] Learning the CIB

Thanks andrew!
The cluster worked ok with the CIB I made here, but no resources were
working ( namely the IPaddr that I configured to be my Virtual IP ). I
realised that I need to declare constraints so as to have my resources
running on the cluster. Now I'm studying how to get them running but still
no results.
The CIB I've been working on are attached to the mail ( it's a draft i'm
still working on ).
The biggest doubt for now is how do I start a resource? I mean... I want to
make all the resources defined on both groups avaiable. What should I do?
Concerning the expression directive I have a operation property that has the
following values:
lt - ?? ( less than? )
gt - ?? ( greater than? )
lte - ?? (less than or equal to? )
gte - ?? (greater than or equal?)
eq - ?? (equal?)
ne - ?? (not equal?)
defined - Ok...
not_defined - OK.
Do you confirm my guesses ( that are placed in the parenthesis )?
