Method Details [hide private]

__init__(self, opts, args)
(Constructor)

source code 

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

Overrides: object.__init__
(inherited documentation)

CheckHostname(path)
Static Method

source code 

Ensures hostname matches ssconf value.

Parameters:
  • path - Path to ssconf file

UpgradeNetworks(self)

source code 
Decorators:
  • @OrFail("Setting networks")

UpgradeCluster(self)

source code 
Decorators:
  • @OrFail("Upgrading cluster")

UpgradeGroups(self)

source code 
Decorators:
  • @OrFail("Upgrading groups")

GetExclusiveStorageValue(self)

source code 

Return a conservative value of the exclusive_storage flag.

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

ChangeDiskDevType(self, disk, dev_type_map)

source code 

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

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

UpgradeInstances(self)

source code 

Upgrades the instances' configuration.

Decorators:
  • @OrFail("Upgrading instance with spindles")

UpgradeFileStoragePaths(self)

source code 
Decorators:
  • @OrFail("Upgrading file storage paths")

UpgradeNodeIndices(self)

source code 
Decorators:
  • @OrFail("Changing node indices")

UpgradeInstanceIndices(self)

source code 
Decorators:
  • @OrFail("Changing instance indices")

UpgradeFilters(self)

source code 
Decorators:
  • @OrFail("Adding filters")

UpgradeTopLevelDisks(self)

source code 

Upgrades the disks as config top level citizens.

Decorators:
  • @OrFail("Set top level disks")

UpgradeDiskTemplate(self)

source code 
Decorators:
  • @OrFail("Removing disk template")

UpgradeDiskNodes(self)

source code 

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.

Decorators:
  • @OrFail("Upgrading disk nodes")

DowngradeSshKeyParams(self)

source code 

Removes the SSH key type and bits parameters from the config.

Also fails if these have been changed from values appropriate in lower Ganeti versions.

Decorators:
  • @OrFail("Removing SSH parameters")
