Comment 6 Itzhak 2020-10-15 16:05:32 UTC
I will try to check this bug on Monday

Comment 7 Itzhak 2020-10-19 14:14:06 UTC
Currently I don't have a cluster with vSphere LSO 4.6, so I can't test it today. 
If someone else has a cluster with the conf above let me know. 
If not, I will try to deploy a new cluster tomorrow.

Comment 8 Itzhak 2020-10-22 06:14:46 UTC
I used a Vsphere LSO 4.6 to check the bug.

Steps I did to reproduce the bug:

1. I scale down the deployment of the osd-0 by executing this command:
$oc scale deployment rook-ceph-osd-0 --replicas=0 -n openshift-storage

2. Check that only 2 OSD's are up instead of 3.

3. Go to Compute-Nodes
4. Click on Disks tab
5. Click on the kebab action of disk with "Not responding" status ->  Start disk replacement
6. Click on Replace and verify that I see the "rebalancing is in progress" warning, 
   but still, I can perform the replacement(added a screenshot). 
7. Try to click on the replace button and see that the disk can be replaced(added a screenshot).
