RHEA-2018:2586 - Product Enhancement Advisory

Topic

Updated packages that resolve various issues are now available for Red Hat
OpenStack Platform 13.0 (Queens) for RHEL 7.

Description

Red Hat OpenStack Platform provides the facilities for building, deploying, and monitoring a private or public infrastructure-as-a-service (IaaS) cloud running on commonly available physical hardware.

Changes to the ceph component:

• With this update, Ceph storage is supported by KVM virtualization on all CPU architectures supported by Red Hat. (BZ#1606224)

Changes to the ceph-ansible component:

• Ceph OSD containers started with a 3 GB memory limit. When a Ceph cluster is in recovery, it is possible for additional OSD memory to be consumed beyond 3 GB that can result in the OSD crashing. This results in additional recoveries that might have the same problem and created a cascading failure in the entire Ceph cluster. ceph-ansible v3.1.0rc10 now starts Ceph OSDs with a default of 5 GB of memory.

To override the default ceph_osd_docker_memory_limit, clear the value of the CephAnsibleExtraConfig parameter, and set the ceph_osd_docker_memory_limit paramter to 5g in a Heat environment file. (BZ#1600112)
