>>Issues:

1. Too many warning messages as above while running the must-gather

2. Seems like some commands have changed in OCP 4.3, hence better to align the commands with OCP version

3. Even though must-gather passed, most of the relevant logs and command outputs were not collected. Full output pasted in Additional Info

Setup:

1. Platform: VMware VMFS
2. OS: RHCOS
3. CPU=4, Memory=16GB (this was not a production based cluster)
4. OCS version : 4.2.1

Version of all relevant components (if applicable):
---------------------------------------------------------------------------
$ oc get clusterversion
NAME      VERSION   AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.3.0     True        False         73m     Cluster version is 4.3.0


Must-gather image : "quay.io/rhceph-dev/ocs-must-gather:latest-4.2"
