Changes
| Change | Element | Description |
|---|---|---|
| Published class | Cluster | Cluster-wide Cluster metadata |
| Published class | Cluster_host | Cluster member metadata |
| Published class | probe_result | A set of properties that describe one result element of SR.probe. Result elements and properties can change dynamically based on changes to the the SR.probe input-parameters or the target. |
| Published class | sr_stat | A set of high-level properties associated with an SR. |
| Published field | Cluster.cluster_config | Contains read-only settings for the cluster, such as timeouts and other options. It can only be set at cluster create time |
| Published field | Cluster.cluster_hosts | A list of the cluster_host objects associated with the Cluster |
| Published field | Cluster.cluster_stack | Simply the string 'corosync'. No other cluster stacks are currently supported |
| Published field | Cluster.cluster_stack_version | Version of cluster stack, not writable via the API. Defaulting to 2 for backwards compatibility when upgrading from a cluster without this field, which means it is necessarily running version 2 of corosync, the only cluster stack supported so far. |
| Published field | Cluster.cluster_token | The secret key used by xapi-clusterd when it talks to itself on other hosts |
| Published field | Cluster.other_config | Additional configuration |
| Published field | Cluster.pending_forget | Internal field used by Host.destroy to store the IP of cluster members marked as permanently dead but not yet removed |
| Published field | Cluster.pool_auto_join | True if automatically joining new pool members to the cluster. This will be `true` in the first release |
| Published field | Cluster.uuid | Unique identifier/object reference |
| Published field | Cluster_host.PIF | Reference to the PIF object |
| Published field | Cluster_host.cluster | Reference to the Cluster object |
| Published field | Cluster_host.enabled | Whether the cluster host believes that clustering should be enabled on this host. This field can be altered by calling the enable/disable message on a cluster host. Only enabled members run the underlying cluster stack. Disabled members are still considered a member of the cluster (see joined), and can be re-enabled by the user. |
| Published field | Cluster_host.host | Reference to the Host object |
| Published field | Cluster_host.joined | Whether the cluster host has joined the cluster. Contrary to enabled, a host that is not joined is not considered a member of the cluster, and hence enable and disable operations cannot be performed on this host. |
| Published field | Cluster_host.other_config | Additional configuration |
| Published field | Cluster_host.uuid | Unique identifier/object reference |
| Published field | probe_result.complete | True if this configuration is complete and can be used to call SR.create. False if it requires further iterative calls to SR.probe, to potentially narrow down on a configuration that can be used. |
| Published field | probe_result.configuration | Plugin-specific configuration which describes where and how to locate the storage repository. This may include the physical block device name, a remote NFS server and path or an RBD storage pool. |
| Published field | probe_result.extra_info | Additional plugin-specific information about this configuration, that might be of use for an API user. This can for example include the LUN or the WWPN. |
| Published field | probe_result.sr | Existing SR found for this configuration |
| Published field | sr_stat.clustered | Indicates whether the SR uses clustered local storage. |
| Published field | sr_stat.free_space | Number of bytes free on the backing storage (in bytes) |
| Published field | sr_stat.health | The health status of the SR. |
| Published field | sr_stat.name_description | Longer, human-readable description of the SR. Descriptions are generally only displayed by clients when the user is examining SRs in detail. |
| Published field | sr_stat.name_label | Short, human-readable label for the SR. |
| Published field | sr_stat.total_space | Total physical size of the backing storage (in bytes) |
| Published field | sr_stat.uuid | Uuid that uniquely identifies this SR, if one is available. |
| Published message | Cluster.create | Creates a Cluster object and one Cluster_host object as its first member |
| Published message | Cluster.destroy | Destroys a Cluster object and the one remaining Cluster_host member |
| Published message | Cluster.get_network | Returns the network used by the cluster for inter-host communication, i.e. the network shared by all cluster host PIFs |
| Published message | Cluster.pool_create | Attempt to create a Cluster from the entire pool |
| Published message | Cluster.pool_destroy | Attempt to destroy the Cluster_host objects for all hosts in the pool and then destroy the Cluster. |
| Published message | Cluster.pool_force_destroy | Attempt to force destroy the Cluster_host objects, and then destroy the Cluster. |
| Published message | Cluster.pool_resync | Resynchronise the cluster_host objects across the pool. Creates them where they need creating and then plugs them |
| Published message | Cluster_host.create | Add a new host to an existing cluster. |
| Published message | Cluster_host.destroy | Remove the host from an existing cluster. This operation is allowed even if a cluster host is not enabled. |
| Published message | Cluster_host.disable | Disable cluster membership for an enabled cluster host. |
| Published message | Cluster_host.enable | Enable cluster membership for a disabled cluster host. |
| Published message | Cluster_host.force_destroy | Remove a host from an existing cluster forcefully. |
| Published message | SR.probe_ext | Perform a backend-specific scan, using the given device_config. If the device_config is complete, then this will return a list of the SRs present of this type on the device, if any. If the device_config is partial, then a backend-specific scan will be performed, returning results that will guide the user in improving the device_config. |
| Changed field | Cluster.token_timeout | the unit is now seconds |
| Changed field | Cluster.token_timeout_coefficient | the unit is now seconds |
