* Previously, the wrong calculating method was used when counter master and worker nodes. With this update, the correct worker nodes are calculated when nodes have both the `master` and `worker` role. (link:https://bugzilla.redhat.com/show_bug.cgi?id=1951901[*BZ#1951901*])

Worker 0

Description of problem:
in all in one cluster, a node act both as master and worker, when we count worker nodes the number for worker nodes will be 0 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. setup All in One OCP cluster with 3 masters(workers)
2. goes to Compute -> Nodes, click the Filter dropdown

Actual results:
2. in Role filter, it shows Worker 0

Expected results:
2. since we have three workers, we should show Worker 3

Additional info:

Comment 1 Jakub Hadvig 2021-04-21 09:27:45 UTC
Looks like the `getNodeRole` filter is not taking in count case where master nodes are also workers. Triaging to DevConsole team for further investigation.

Comment 2 Andrew Ballantyne 2021-04-26 14:08:52 UTC
Not a DevConsole issue, triaging to Kubevirt for further investigation.

Comment 3 Yaacov Zamir 2021-04-27 11:36:52 UTC
looks like the code that check if node is worker or admin is in the management console:

moving to management compoenent

correct worker node count

set up single node cluster in which the node are both master and worker, Nodes list filter shows Worker count is 1 and Master count is 1, this is correct
