Description Antonio Murdaca 2019-08-08 09:02:30 UTC

Description of problem:

When using a custom pool for a subset of the worker nodes, the worker MCP shows an outdated machine count until the MCP is synced again (this can also be manually triggered by a worker MCP update like setting maxUnavailable).


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

4.2


How reproducible:

100%


Steps to Reproduce:
1. set a node to be infra and create an infra MCP/MC inheriting from worker
2. oc describe mcp worker
3.

Actual results:

On a 3 nodes cluster and 1 infra node:

oc describe mcp worker
...
  Machine Count:              3
...


Expected results:

oc describe mcp worker
...
  Machine Count:              2
...

Hi 

I found this bug still exist in ocp4.5.4, before I have 6 worker nodes, but after I changed one of it to infra node, the machinecount of mcp is still 6

[student@workstation ~]$ oc get nodes -l node-role.kubernetes.io/worker
NAME       STATUS   ROLES    AGE    VERSION
worker01   Ready    worker   151d   v1.18.3+012b3ec

worker04   Ready    worker   19m    v1.18.3+012b3ec
worker05   Ready    worker   19m    v1.18.3+012b3ec
[student@workstation ~]$ oc get mcp worker

The only way I found to reflect the new machinecount is to recreate the MCP
[student@workstation ~]$ oc get clusterversion

version   4.5.4     True        False         151d    Cluster version is 4.5.4
