Undocumented

@staticmethod
def ChangeInstanceIndices(config_data, old_key_field, new_key_field):

Undocumented

@staticmethod
def CheckHostname(path):

Ensures hostname matches ssconf value.

Parameters
pathPath to ssconf file
@staticmethod

def __init__(self, opts, args):

Undocumented

def ChangeDiskDevType(self, disk, dev_type_map):

Replaces disk's dev_type attributes according to the given map.

This can be used for both, up or downgrading the disks.

def ChangeNodeIndices(self, config_data, old_key_field, new_key_field):

Undocumented

def DowngradeAll(self):

Undocumented

@OrFail('Adding xen_cmd parameter')
def DowngradeXenSettings(self):

Re-adds the xen_cmd setting to the configuration.

def GetExclusiveStorageValue(self):

Return a conservative value of the exclusive_storage flag.

Return True if the cluster or at least a nodegroup have the flag set.

def RemovePhysicalId(self, disk):

Undocumented

def Run(self):

Main program.

def SetupLogging(self):

Configures the logging module.

def UpgradeAll(self):

Undocumented

@OrFail('Upgrading cluster')
def UpgradeCluster(self):

Undocumented

def UpgradeDiskDevType(self, disk):

Upgrades the disks' device type.

@OrFail('Upgrading disk nodes')
def UpgradeDiskNodes(self):

Specify the nodes from which a disk is accessible in its definition.

For every disk that is attached to an instance, get the UUIDs of the nodes that it's accessible from. There are three main cases: 1) Internally mirrored disks (DRBD): These disks are accessible from two nodes, so the nodes list will include these. Their children (data, meta) are also accessible from two nodes, therefore they will inherit the nodes of the parent. 2) Externally mirrored disks (Blockdev, Ext, Gluster, RBD, Shared File): These disks should be accessible from any node in the cluster, therefore the nodes list will be empty. 3) Single-node disks (Plain, File): These disks are accessible from one node only, therefore the nodes list will consist only of the primary instance node.
