Constants
- CLEAN_FINISHED_TASKS
- GET
- REMOVE
- SET_MASTER
- UPDATE
Public Instance Methods
Currently, the storage pool manager (SPM) fails to switch to another host if the SPM has uncleared tasks. Clearing all finished tasks enables the SPM switching.
For example, to clean all the finished tasks on a data center with ID `123` send a request like this:
- source
POST /ovirt-engine/api/datacenters/123/cleanfinishedtasks
With a request body like this:
- source,xml
<action/>
@param opts [Hash] Additional options.
@option opts [Boolean] :async Indicates if the action should be performed asynchronously.
@option opts [Hash] :headers ({}) Additional HTTP headers.
@option opts [Hash] :query ({}) Additional URL query parameters.
@option opts [Integer] :timeout (nil) The timeout for this request, in seconds. If no value is explicitly
given then the timeout set globally for the connection will be used.
@option opts [Boolean] :wait (true) If `true` wait for the response.
# File lib/ovirtsdk4/services.rb, line 6339 def clean_finished_tasks(opts = {}) internal_action(:cleanfinishedtasks, nil, CLEAN_FINISHED_TASKS, opts) end
Locates the `clusters` service.
@return [ClustersService] A reference to `clusters` service.
# File lib/ovirtsdk4/services.rb, line 6554 def clusters_service @clusters_service ||= ClustersService.new(self, 'clusters') end
Get a data center.

Removes the data center.
- source
DELETE /ovirt-engine/api/datacenters/123
Without any special parameters, the storage domains attached to the data center are detached and then removed from the storage. If something fails when performing this operation, for example if there is no host available to remove the storage domains from the storage, the complete operation will fail.
If the `force` parameter is `true` then the operation will always succeed, even if something fails while removing one storage domain, for example. The failure is just ignored and the data center is removed from the database anyway.
@param opts [Hash] Additional options.
@option opts [Boolean] :async Indicates if the remove should be performed asynchronously. @option opts [Boolean] :force Indicates if the operation should succeed, and the storage domain removed from the database, even if
something fails during the operation. This parameter is optional, and the default value is `false`.
@option opts [Hash] :headers ({}) Additional HTTP headers.
@option opts [Hash] :query ({}) Additional URL query parameters.
@option opts [Integer] :timeout (nil) The timeout for this request, in seconds. If no value is explicitly
given then the timeout set globally for the connection will be used.
@option opts [Boolean] :wait (true) If `true` wait for the response.
# File lib/ovirtsdk4/services.rb, line 6451 def remove(opts = {}) internal_remove(REMOVE, opts) end
Locates the service corresponding to the given path.
@param path [String] The path of the service.
@return [Service] A reference to the service.
# File lib/ovirtsdk4/services.rb, line 6642 def service(path) if path.nil? || path == '' return self end if path == 'clusters' return clusters_service end if path.start_with?('clusters/') return clusters_service.service(path[9..-1]) end if path == 'iscsibonds' return iscsi_bonds_service end if path.start_with?('iscsibonds/') return iscsi_bonds_service.service(path[11..-1]) end if path == 'networks' return networks_service end if path.start_with?('networks/') return networks_service.service(path[9..-1]) end if path == 'permissions' return permissions_service end if path.start_with?('permissions/') return permissions_service.service(path[12..-1]) end if path == 'qoss' return qoss_service end if path.start_with?('qoss/') return qoss_service.service(path[5..-1]) end if path == 'quotas' return quotas_service end if path.start_with?('quotas/') return quotas_service.service(path[7..-1]) end if path == 'storagedomains' return storage_domains_service end if path.start_with?('storagedomains/') return storage_domains_service.service(path[15..-1]) end raise Error.new("The path \"#{path}\" doesn't correspond to any service") end
Used for manually setting a storage domain in the data center as a master. For example, for setting a storage domain with ID '456' as a master on a data center with ID '123', send a request like this:
- source
POST /ovirt-engine/api/datacenters/123/setmaster
With a request body like this:
- source,xml
<action>
<storage_domain id="456"/>
</action>
The new master storage domain can be also specified by its name.
@param opts [Hash] Additional options.
@option opts [Boolean] :async Indicates if the action should be performed asynchronously.
@option opts [StorageDomain] :storage_domain The new master storage domain for the data center.
@option opts [Hash] :headers ({}) Additional HTTP headers.
@option opts [Hash] :query ({}) Additional URL query parameters.
@option opts [Integer] :timeout (nil) The timeout for this request, in seconds. If no value is explicitly
given then the timeout set globally for the connection will be used.
@option opts [Boolean] :wait (true) If `true` wait for the response.
# File lib/ovirtsdk4/services.rb, line 6498 def set_master(opts = {}) internal_action(:setmaster, nil, SET_MASTER, opts) end
Attach and detach storage domains to and from a data center.
For attaching a single storage domain we should use the following POST request:
- source
POST /ovirt-engine/api/datacenters/123/storagedomains
With a request body like this:
- source,xml
<storage_domain>
<name>data1</name>
</storage_domain>
For detaching a single storage domain we should use the following DELETE request:
- source
DELETE /ovirt-engine/api/datacenters/123/storagedomains/123
@return [AttachedStorageDomainsService] A reference to `storage_domains` service.
# File lib/ovirtsdk4/services.rb, line 6631 def storage_domains_service @storage_domains_service ||= AttachedStorageDomainsService.new(self, 'storagedomains') end
Updates the data center.
The `name`, `description`, `storage_type`, `version`, `storage_format` and `mac_pool` elements are updatable post-creation. For example, to change the name and description of data center `123` send a request like this:
- source
PUT /ovirt-engine/api/datacenters/123
With a request body like this:
- source,xml
<data_center>
<name>myupdatedname</name> <description>An updated description for the data center</description>
</data_center>
@param data_center [DataCenter] The data center that is being updated. @param opts [Hash] Additional options.
@option opts [Boolean] :async Indicates if the update should be performed asynchronously.
@option opts [Hash] :headers ({}) Additional HTTP headers.
@option opts [Hash] :query ({}) Additional URL query parameters.
@option opts [Integer] :timeout (nil) The timeout for this request, in seconds. If no value is explicitly
given then the timeout set globally for the connection will be used.
@option opts [Boolean] :wait (true) If `true` wait for the response.
@return [DataCenter]
# File lib/ovirtsdk4/services.rb, line 6545 def update(data_center, opts = {}) internal_update(data_center, DataCenter, UPDATE, opts) end
