Remediation
Red Hat statement
* Red Hat OpenStack Platform deployments use the ceph package directly from the Ceph channel; the RHOSP package will not be updated at this time. * This issue did not affect the versions of ceph as shipped with Red Hat Enterprise Linux 8 as they did not include support for RGW. * Red Hat OpenShift Container Storage (RHOCS) 4 shipped ceph package for the usage of RHOCS 4.2 only, that has reached End Of Life. The shipped version of ceph package is no longer used and supported with the release of RHOCS 4.3.
