<font size="-1"><font face="Helvetica, Arial, sans-serif">So colocation
is biting me in the ass again and I cant figure this one out.<br>
I have a group of iSCSI devices that then go into an md raid device
that then goes into an lvm device which then gets mounted and then
exported by nfs. Thoughout this whole project I've had the resources
trying to start on nodes where the resource it depends on wasnt even
running. But those were usually when I failed something and they tried
to migrate. Right now I'm having problems simply starting the final
resource, the nfs export<br>
<br>
All the resource are started on the same node except for the
ocf:hearbeat:nfsserver resource. For some reason it refuses to start on
the same node, even though I have a colocation rule.<br>
All the other resources are on node 'nas01', but every time I start up
the nfsserver resource it starts on 'nas02'. I've stopped it, cleaned
it, started it back up. All have no effect. Ive even tried reversing
the order of the resources in the colocation rule as last time I had
this problem it was cause they were backwards.<br>
<br>
Below is info from the crm util, and attached is the output of
`cibadmin -Q`<br>
