_ExpandMultiNames(mode, names, client=None)

source code

Expand the given names using the passed mode.

For _EXPAND_CLUSTER, all instances will be returned. For _EXPAND_NODES_PRI/SEC, all instances having those nodes as primary/secondary will be returned. For _EXPAND_NODES_BOTH, all instances having those nodes as either primary or secondary will be returned. For _EXPAND_INSTANCES, the given instances will be returned.

Parameters:

mode - one of _EXPAND_CLUSTER, _EXPAND_NODES_BOTH, _EXPAND_NODES_PRI, _EXPAND_NODES_SEC or _EXPAND_INSTANCES
names - a list of names; for cluster, it must be empty, and for node and instance it must be a list of valid item names (short names are valid as usual, e.g. node1 instead of node1.example.com)

Returns: list

the list of names after the expansion

Raises:

errors.ProgrammerError - for unknown selection type
errors.OpPrereqError - for invalid input parameters

_EnsureInstancesExist(client, names)

names (list) - the list of instance names to query

Raises:

errors.OpPrereqError - in case any instance is missing

GenericManyOps(operation, fn)

args (list) - should contain two elements, the old and the new instance names

Returns: int

the desired exit code

ActivateDisks(opts, args)

source code

Activate an instance's disks.

This serves two purposes:

it allows (as long as the instance is not running) mounting the disks and modifying them from the node
it repairs inactive secondary drbds

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code

DeactivateDisks(opts, args)

source code

Deactivate an instance's disks.

This function takes the instance name, looks for its primary node and the tries to shutdown its block devices on that node.

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code

RecreateDisks(opts, args)

source code

Recreate an instance's disks.

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code

GrowDisk(opts, args)

source code

Grow an instance's disks.

Parameters:

opts - the command line options selected by the user
args (list) - should contain three elements, the target instance name, the target disk id, and the target growth

Returns: int

the desired exit code

_StartupInstance(name, opts)

source code

Startup instances.

This returns the opcode to start an instance, and its decorator will wrap this into a loop starting all desired instances.

Parameters:

name - the name of the instance to act on
opts - the command line options selected by the user

Returns:

the opcode needed for the operation

_RebootInstance(name, opts)

source code

Reboot instance(s).

This returns the opcode to reboot an instance, and its decorator will wrap this into a loop rebooting all desired instances.

Parameters:

name - the name of the instance to act on
opts - the command line options selected by the user

Returns:

the opcode needed for the operation

_ShutdownInstance(name, opts)

source code

Shutdown an instance.

This returns the opcode to shutdown an instance, and its decorator will wrap this into a loop shutting down all desired instances.

Parameters:

name - the name of the instance to act on
opts - the command line options selected by the user

Returns:

the opcode needed for the operation

ReplaceDisks(opts, args)

source code

Replace the disks of an instance

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code

FailoverInstance(opts, args)

source code

Failover an instance.

The failover is done by shutting it down on its present node and starting it on the secondary.

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code

MigrateInstance(opts, args)

source code

Migrate an instance.

The migrate is done without shutdown.

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code

MoveInstance(opts, args)

source code

Move an instance.

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code

ConnectToInstanceConsole(opts, args)

source code

Connect to the console of an instance.

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code

_DoConsole(console, show_command, cluster_name, feedback_fn=ToStdout, _runcmd_fn=utils.RunCmd)

source code

Acts based on the result of opcodes.OpInstanceConsole.

Parameters:

console (objects.InstanceConsole) - Console object
show_command (bool) - Whether to just display commands
cluster_name (string) - Cluster name as retrieved from master daemon

_FormatBlockDevInfo(idx, top_level, dev, roman)

source code

Show block device information.

This is only used by ShowInstanceConfig, but it's too big to be left for an inline definition.

Parameters:

idx (int) - the index of the current disk
top_level (boolean) - if this a top-level disk?
dev (dict) - dictionary with disk information
roman (boolean) - whether to try to use roman integers

Returns:

a list of either strings, tuples or lists (which should be formatted at a higher indent level)

ShowInstanceConfig(opts, args)

source code

Compute instance run-time status.

Parameters:

opts - the command line options selected by the user
args (list) - either an empty list, and then we query all instances, or should contain a list of instance names

Returns: int

the desired exit code

_ConvertNicDiskModifications(mods)

source code

Converts NIC/disk modifications from CLI to opcode.

When opcodes.OpInstanceSetParams was changed to support adding/removing disks at arbitrary indices, its parameter format changed. This function converts legacy requests (e.g. "--net add" or "--disk add:size=4G") to the newer format and adds support for new-style requests (e.g. "--new 4:add").

Parameters:

mods (list of tuples) - Modifications as given by command line parser

Returns: list of tuples

Modifications as understood by opcodes.OpInstanceSetParams

SetInstanceParams(opts, args)

source code

Modifies an instance.

All parameters take effect only at the next restart of the instance.

Parameters:

opts - the command line options selected by the user
args (list) - should contain only one element, the instance name

Returns: int

the desired exit code
