Fuel UI show a zero HDD size in Environment Capacity

[Alexey Galkin]

Detailed bug description:
 Fuel UI displays an incorrect size of hard drives (0 bytes).

Steps to reproduce:
 1. Create new env.
 2. Add nodes into env.
 3. Look at env dashboard.

Expected results:
Capacity
 CPU (Cores) 2 (4) | RAM8.0 GB | HDD 2 TB
Node Statistics
 Total Nodes 4
 Controller 2
 Compute 2

Actual result:
Capacity
 CPU (Cores) 2 (4) | RAM8.0 GB | HDD 0 bytes
Node Statistics
 Total Nodes 4
 Controller 2
 Compute 2

Reproducibility:
 For all types of enviroments.

Workaround:
  -

Impact:
 Сustomer need to see the correct information of HDD size.

Alexey, it was discussed here https://bugs.launchpad.net/fuel/+bug/1375750 that HDD cluster capacity is sum of storage nodes' HDD. In your case there are no storage nodes in the environment, so HDD cluster capacity value is equal to 0.

Please, make this ticket 'New' again, if you do not agree with this idea of cluster capacity calculation.

I saw the issue on MOS 9.0, moved to Confirmed state.

Timur, what number do you expect to see here? Your cluster doesn't have any Storage nodes

[Timur Nurlygayanov (tnurlygayanov)]

I'm going to deploy my own environment to investigate all possible options and cases for deployments and how UI works for all of them. Right now we have configurations where it works fine and we also have configurations where it doesn't work and we need to understand the problem area.

[Vitaly Kramskikh (vkramskikh)]

Timur, most likely it's consequence of implementing blueprint redesign-of-node-roles-panel, but that's expected behaviour. Take a look at the spec: https://review.openstack.org/#/c/271950/7/specs/9.0/redesign-of-node-roles-panel.rst

Hi team,

it looks like we still have issues with HDD field.

Steps To Reproduce:
1. Create new environment in MOS 9.0
2. Add 3 controller nodes. Verify that HDD size is "0 bytes" in Fuel UI > env details.
3. Add 2 compute nodes to the environment. Verify that HDD size is "0 bytes" in Fuel UI > env details.
4. Add role Cinder to the compute nodes. Check the size of HDD for the cluster. It is equal to 384 Gb on my environment, 2 compute+cinder nodes have 192Gb+192Gb in total, 384 Gb is the full sum of HDD space of compute + storage nodes (it is actually not true)
5. Update the default configuration for disks partitioning for Cinder nodes. Allocate 40 Gb on each node for Cinder LVM. Check information about HDD size for the environment. It is still unchanged, 384 Gb total. In fact, changes in disks partitioning don't affect the size of HDD for the environment.

Observed Result:
HDD size for the cluster depends only on roles and doesn't depend on size of the real partitions which allocated for storage.

[Vitaly Kramskikh (vkramskikh)]

I agree only partitions used for storage should be counted. It seems to be an issue in feature design - probably we need a separate blueprint to address it as it requires backend changes - UI doesn't have access to partition descriptions and capacity calculation becomes too complex for UI.

    Revert "Cluster capacity calculation fix"

    Cluster capacity calculation take into account hardware parameters
    of all the cluster nodes despite on their roles.
