It does produces the XML above (and which I expected it to produce).
Unfortunately- that XML doesn't do what I want it to do (it actually

It sets sequential=false for the items in that set and it definitely
behaves differently when I use it.

Not exactly. That may have been a poor example but what I was trying
to achieve was the idea that these 2 services must run on the same

True- but then you run into the problem of not being able to have
groups of groups. So if I create a group for my filesystems- I can't

There are maintenance reasons for some of these requirements- for

Whenever you make something idiot proof, the universe invents a bigger idiot.
I'm that idiot I guess.

Except colocation resources also include order unless you specifically

I apologize if this is obvious or has been answered before but my
foogle-fu is failing me.
I'm trying to create a resource dependency tree similar to this one from VCS:
// resource dependency tree

{
Oracle OraInstance1

I was hoping to avoid having to parse XML but if that's the only

Is there some way of listing all resources that use a specific
resource agent using crm shell?
For example:
# crm resource list
stonith-sbd(stonith:external/sbd) Started
IP1 (ocf::heartbeat:IPaddr2) Started
IP2 (ocf::heartbeat:IPaddr2) Started
FS1 (ocf::heartbeat:Filesystem) Started
FS2
