+++ This bug was initially created as a clone of Bug #2232384 +++

1. Describe the issue:

We need to document the steps to modify the OSD pod resources persistently.

We have already documented the steps to change it for other pods like
mgr, mds, rgw in here:

https://access.redhat.com/documentation/en-us/red_hat_openshift_data_foundation/4.13/html/troubleshooting_openshift_data_foundation/changing-resources-for-the-openshift-data-foundation-components_rhodf#changing_the_cpu_and_memory_resources_on_the_rook_ceph_pods

1. Describe the task you were trying to accomplish:

Increase/decrease OSD pod memory and CPU limits and requests

1. Suggestions for improvement:

Include the steps for MON and OSDs from this KCS:

For MONs, as I understand the steps are the same for the other daemons.
But for OSDs, the steps are a bit different.

For reference:

https://bugzilla.redhat.com/show_bug.cgi?id=2160294

We need to get ack from the Engineering team and get this QE tested.

This bug having no release flag set previously, is now set with release flag 'odf‑4.14.0' to '?', and so is being proposed to be fixed at the ODF 4.14.0 release. Note that the 3 Acks (pm_ack, devel_ack, qa_ack), if any previously set while release flag was missing, have now been reset since the Acks are to be set against a release flag.

@etamir@redhat.com @ebenahar@redhat.com @muagarwa@redhat.com – Kindly review this bug and let us know if the KCS article should be tested and included in the docs.

We currently have https://access.redhat.com/documentation/en-us/red_hat_openshift_data_foundation/4.14/html/troubleshooting_openshift_data_foundation/changing-resources-for-the-openshift-data-foundation-components_rhodf in the documents. IMHO, It would make sense to merge the KCS content into this section.

Agreed with Eran

Eran and Mudit, please see KCS #7069646, (https://access.redhat.com/solutions/7069646)

We really need better Docs for this

Best regards,
Manny

Updated the priority which wasn't urgent for some reason.
@asriram@redhat.com when can we get the OSD section https://access.redhat.com/solutions/6959127#:~:text=For%20osd%20pods%2C%20we%20need%20to%20edit%20resources%20on%20the%20storageDeviceSets%20section. into the docs sooner than later?
