Chapter 7. 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. CephClusterFSID The Ceph cluster FSID. Must be a UUID. CephClusterName The Ceph cluster name. The default value is 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.

CinderEnableIscsiBackend Whether to enable or not the Iscsi backend for OpenStack Block Storage (cinder). The default value is True . CinderEnableNfsBackend Whether to enable or not the NFS backend for OpenStack Block Storage (cinder). The default value is False . CinderEnableRbdBackend Whether to enable or not the Rbd backend for OpenStack Block Storage (cinder). The default value is False . CinderEtcdLocalConnect When running OpenStack Block Storage (cinder) A/A, whether to connect to Etcd via the local IP for the Etcd network. If set to true, the ip on the local node will be used. If set to false, the VIP on the Etcd network will be used instead. Defaults to false. The default value is False . CinderImageConversionNfsOptions NFS mount options when using an NFS share for the OpenStack Block Storage (cinder) image conversion directory. The default value is _netdev,bg,intr,context=system_u:object_r:container_file_t:s0 . CinderImageConversionNfsShare When set, the NFS share to be used for the OpenStack Block Storage (cinder) image conversion directory. CinderISCSIAvailabilityZone The availability zone of the Iscsi OpenStack Block Storage (cinder) backend. When set, it overrides the default CinderStorageAvailabilityZone. CinderISCSIHelper The iSCSI helper to use with cinder. The default value is lioadm . CinderISCSIProtocol Whether to use TCP ( iscsi ) or iSER RDMA ( iser ) for iSCSI. The default value is iscsi . CinderLVMLoopDeviceSize The size of the loopback file used by the cinder LVM driver. The default value is 10280 . CinderNasSecureFileOperations Controls whether security enhanced NFS file operations are enabled. Valid values are auto , true or false . Effective when CinderEnableNfsBackend is true. The default value is False . CinderNasSecureFilePermissions Controls whether security enhanced NFS file permissions are enabled. Valid values are auto , true or false . Effective when CinderEnableNfsBackend is true. The default value is False . CinderNfsAvailabilityZone The availability zone of the NFS OpenStack Block Storage (cinder) backend. When set, it overrides the default CinderStorageAvailabilityZone. CinderNfsMountOptions Mount options for NFS mounts used by OpenStack Block Storage (cinder) NFS backend. Effective when CinderEnableNfsBackend is true. The default value is context=system_u:object_r:container_file_t:s0 . CinderNfsServers NFS servers used by OpenStack Block Storage (cinder) NFS backend. Effective when CinderEnableNfsBackend is true. CinderNfsSnapshotSupport Whether to enable support for snapshots in the NFS driver. Effective when CinderEnableNfsBackend is true. The default value is True . CinderPassword The password for the cinder service and database account. CinderRbdAvailabilityZone The availability zone of the RBD OpenStack Block Storage (cinder) backend. When set, it overrides the default CinderStorageAvailabilityZone. CinderRbdExtraPools List of extra Ceph pools for use with RBD backends for OpenStack Block Storage (cinder). An extra OpenStack Block Storage (cinder) RBD backend driver is created for each pool in the list. This is in addition to the standard RBD backend driver associated with the CinderRbdPoolName. CinderRbdFlattenVolumeFromSnapshot Whether RBD volumes created from a snapshot should be flattened in order to remove a dependency on the snapshot. The default value is False . CinderRbdPoolName The Ceph pool to use for cinder volumes. The default value is volumes . CinderRpcResponseTimeout Cinder's RPC response timeout, in seconds. The default value is 60 . CinderStorageAvailabilityZone The OpenStack Block Storage (cinder) service's storage availability zone. The default value is nova . CinderVolumeCluster The cluster name used for deploying the cinder-volume service in an active-active (A/A) configuration. This configuration requires the OpenStack Block Storage (cinder) backend drivers support A/A, and the cinder-volume service not be managed by pacemaker. 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. DockerCinderVolumeUlimit Ulimit for OpenStack Block Storage (cinder) Volume Container. The default value is ['nofile=131072'] . EnableEtcdInternalTLS Controls whether etcd and the cinder-volume service use TLS for cinder's lock manager, even when the rest of the internal API network is using TLS. The default value is False . MemcacheUseAdvancedPool Use the advanced (eventlet safe) memcached client pool. The default value is True . MultipathdEnable Whether to enable the multipath daemon. The default value is False . NotificationDriver Driver or drivers to handle sending notifications. The default value is noop .
