How reproducible:
Run
oc adm must-gather – /usr/bin/gather_metallb_logs


Actual results:
[must-gather-mg7hd] POD 2022-02-11T19:58:00.172254127Z INFO: MetalLB not detected. Skipping.

Expected results:
Relevant logs should be collected.

Comment 1 Carlos Goncalves 2022-02-14 20:02:08 UTC

It seems the metadata.name in Nikita's deployment is "metallb-operator-sub" and is how it's documented in https://docs.openshift.com/container-platform/4.9/networking/metallb/metallb-operator-install.html.
Perhaps instead of filtering by such user-provided/arbitrary field, we could filter by package?

$ oc get subs -A
NAMESPACE                              NAME                                      PACKAGE                      SOURCE                       CHANNEL
local-storage                          local-storage-operator-subscription       local-storage-operator       internal-registry            4.10
metallb-system                         metallb-operator-sub                      metallb-operator             internal-registry            4.10

openshift-sriov-network-operator       sriov-network-operator-subscription       sriov-network-operator       internal-registry            4.10

Lior, could you please have a look at this issue? Thanks!

Comment 3 Lior Noy 2022-02-23 08:55:33 UTC

The fix PR got lgtm, waiting for the maintainer's action

Comment 6 Lior Noy 2022-03-02 09:02:57 UTC

(In reply to Lior Noy from comment #3)
> The fix PR got lgtm, waiting for the maintainer's action

Also, note that I verified the solution on 2 scenarios:
1. Install the operator via operator hub.
2. Install via yamls. (following the official metallb Openshift doc)

Comment 7 Scott Dodson 2022-07-13 01:59:36 UTC

Nikita, can you verify this bug please?

Comment 8 Nikita 2022-07-13 18:12:07 UTC
