Chapter 8. Block Storage (cinder) Parameters You can modify the cinder service with block storage parameters. Parameter Description ApacheCertificateKeySize Override the private key size used when creating the certificate for this service. ApacheTimeout The timeout in seconds for Apache, which defines duration Apache waits for I/O operations. The default value is 90 . AuthCloudName Entry in clouds.yaml to use for authentication. CephClusterFSID The Ceph cluster FSID. Must be a UUID. CephClusterName The Ceph cluster name. The default value is ceph . CephConfigPath The path where the Ceph Cluster configuration files are stored on the host. The default value is /var/lib/tripleo-config/ceph . CephExternalMultiConfig List of maps describing extra overrides which will be applied when configuring extra external Ceph clusters. If this list is non-empty, ceph-ansible will run an extra count(list) times using the same parameters as the first run except each parameter within each map will override the defaults. If the following were used, the second run would configure the overcloud to also use the ceph2 cluster with all the parameters except /etc/ceph/ceph2.conf would have a mon_host entry containing the value of external_cluster_mon_ips below, and not the default CephExternalMonHost. Subsequent ceph-ansible runs are restricted to just ceph clients. CephExternalMultiConfig may not be used to deploy additional internal Ceph clusters within one OpenStack Orchestration (heat) stack. The map for each list should contain not tripleo-heat-template parameters but ceph-ansible parameters. - cluster: ceph2 fsid: e2cba068-5f14-4b0f-b047-acf375c0004a external_cluster_mon_ips: 172.18.0.5,172.18.0.6,172.18.0.7 keys: - name: "client.openstack" caps: mgr: "allow *" mon: "profile rbd" osd: "osd: profile rbd pool=volumes, profile rbd pool=backups, profile rbd pool=vms, profile rbd pool=images" key: "AQCwmeRcAAAAABAA6SQU/bGqFjlfLro5KxrB1Q==" mode: "0600" dashboard_enabled: false.

If these criteria are not met then the cluster name must be left blank. CinderVolumeOptEnvVars Hash of optional environment variables. CinderVolumeOptVolumes List of optional volumes to be mounted. CinderWorkers Set the number of workers for the block storage service. Note that more workers creates a larger number of processes on systems, which results in excess memory consumption. It is recommended to choose a suitable non-default value on systems with high CPU core counts. 0 sets to the OpenStack internal default, which is equal to the number of CPU cores on the node. The default value is equal to the number of vCPU cores on the physical node. ClusterCommonTag When set to false, a pacemaker service is configured to use a floating tag for its container image name, e.g. REGISTRY/NAMESPACE/IMAGENAME:pcmklatest .
