Whiteboard:
Fixed In Version: ceph-ansible-3.1.0-0.1.rc10.el7cp Doc Type: Bug Fix
Doc Text:
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.
