so it has interfaces in both the management and the storage subnets (as well as
guest).

Subject: Re: advanced networking with public IPs direct to VMs
Hi Rafael
Thanks for the help, really appreciate it.
So rerunning that command with all servers up -
mysql> select * from cloud.storage_pool where cluster_id = 1 and removed is
null;
Empty set (0.00 sec)
mysql>
As for the storage IP no I'm not setting it to be the management IP when I
setup the zone but the output of the SQL command suggests that is what has
happened.
As I said to Dag I am using a different subnet for storage ie.
172.30.3.0/26 - management subnet
172.30.4.0/25 - guest VM subnet
172.30.5.0/28 - storage
the NFS server IP is 172.30.5.2
each compute node has 3 NICs with an IP from each subnet (i am assuming the
management node only needs an IP in the management network ?)
When I add the zone in the UI I have one physical network with management
(cloudbr0), guest (cloudbr1) and storage (cloudbr2).
When I fill in the storage traffic page I use the range 172.16.5.10 - 14 as
free IPs as I exclude the ones already allocated to the compute nodes and the
NFS server.
I think maybe I am doing something wrong in the UI setup but it is not obvious
to me what it is.
What I might try today unless you want me to keep the setup I have for more
outputs is to go back to 2 NICs, one for storage/management and one for guest
VMs.
I think with the 2 NICs setup the mistake I made last time when adding the zone
was to assume storage would just run over management so I did not drag and drop
the storage icon and assign it to cloudbr0 as with the management which I think
is what I should do ?

Jon, do not panic we are here to help you :)
So, I might have mistyped the SQL query. You you use select * from
cloud.storage_pool where cluster_id = 1 and removed is not null ", you are
listing the storage pools removed. Therefore, the right query would be "
select * from cloud.storage_pool where cluster_id = 1 and removed is null "
There is also something else I do not understand. You are setting the
storage IP in the management subnet? I am not sure if you should be doing
like this. Normally, I set all my storages (primary[when working with NFS]
and secondary) to IPs in the storage subnet.
