_ComputeSecondaryNodes(self)

source code

Compute the list of secondary nodes.

This is a simple wrapper over _ComputeAllNodes.

_ComputeAllNodes(self)

source code

Compute the list of all nodes.

Since the data is already there (in the drbd disks), keeping it as a separate normal attribute is redundant and if not properly synchronised can cause problems. Thus it's better to compute it dynamically.

MapLVsByNode(self, lvmap=None, devs=None, node=None)

source code

Provide a mapping of nodes to LVs this instance owns.

This function figures out what logical volumes should belong on which nodes, recursing through a device tree.

Parameters:

lvmap - optional dictionary to receive the 'node' : ['lv', ...] data.

Returns:

None if lvmap arg is given, otherwise, a dictionary of the form { 'nodename' : ['volume1', 'volume2', ...], ... }; volumeN is of the form "vg_name/lv_name", compatible with GetVolumeList()

FindDisk(self, idx)

source code

Find a disk given having a specified index.

This is just a wrapper that does validation of the index.

Parameters:

idx (int) - the disk index

Returns: Disk

the corresponding disk

Raises:

errors.OpPrereqError - when the given index is not valid

ToDict(self)

source code

Instance-specific conversion to standard python types.

This replaces the children lists of objects with lists of standard python types.

Overrides: ConfigObject.ToDict

FromDict(cls, val)
Class Method

source code

Custom function for instances.

Overrides: ConfigObject.FromDict

UpgradeConfig(self)

source code

Fill defaults for missing configuration values.

Overrides: ConfigObject.UpgradeConfig
