Properties [hide private]

Inherited from object: __class__

Method Details [hide private]

__init__(self)
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

HandleRequest(self, req)

source code 

Handle a request.

Overrides: http.server.HttpServerHandler.HandleRequest

perspective_blockdev_addchildren(params)
Static Method

source code 

Add a child to a mirror device.

Note: this is only valid for mirror devices. It's the caller's duty to send a correct disk, otherwise we raise an error.

perspective_blockdev_removechildren(params)
Static Method

source code 

Remove a child from a mirror device.

This is only valid for mirror devices, of course. It's the callers duty to send a correct disk, otherwise we raise an error.

perspective_blockdev_find(params)
Static Method

source code 

Expose the FindBlockDevice functionality for a disk.

This will try to find but not activate a disk.

perspective_blockdev_snapshot(params)
Static Method

source code 

Create a snapshot device.

Note that this is only valid for LVM disks, if we get passed something else we raise an exception. The snapshot device can be remove by calling the generic block device remove call.

perspective_drbd_disconnect_net(params)
Static Method

source code 

Disconnects the network connection of drbd disks.

Note that this is only valid for drbd disks, so the members of the disk list must all be drbd devices.

perspective_drbd_attach_net(params)
Static Method

source code 

Attaches the network connection of drbd disks.

Note that this is only valid for drbd disks, so the members of the disk list must all be drbd devices.

perspective_drbd_wait_sync(params)
Static Method

source code 

Wait until DRBD disks are synched.

Note that this is only valid for drbd disks, so the members of the disk list must all be drbd devices.

perspective_export_info(params)
Static Method

source code 

Query information about an existing export on this node.

The given path may not contain an export, in which case we return None.

perspective_export_list(params)
Static Method

source code 

List the available exports on this node.

Note that as opposed to export_info, which may query data about an export in any path, this only queries the standard Ganeti path (pathutils.EXPORT_DIR).

perspective_upload_file(params)
Static Method

source code 

Upload a file.

Note that the backend implementation imposes strict rules on which files are accepted.

perspective_jobqueue_update(params)
Static Method

source code 

Update job queue.

Decorators:
  • @_RequireJobQueueLock

perspective_jobqueue_purge(params)
Static Method

source code 

Purge job queue.

Decorators:
  • @_RequireJobQueueLock

perspective_jobqueue_rename(params)
Static Method

source code 

Rename a job queue file.
