Ganeti.Objects.Disk

Description

Implementation of the Ganeti Disk config object.

Synopsis

Documentation

devType :: StringSource

Constant for the dev_type key entry in the disk config.

type DiskParams = Container JSValueSource

The disk parameters type.

type DRBDSecret = StringSource

An alias for DRBD secrets

data LogicalVolume Source

Constructors

LogicalVolume
Fields lvGroup :: String lvVolume :: String

Instances

Eq LogicalVolume
Ord LogicalVolume
Show LogicalVolume
JSON LogicalVolume
Validatable LogicalVolume	Check the constraints for a VGLV names (except the \@\dev/@ check).
Arbitrary LogicalVolume

data DiskLogicalId Source

The disk configuration type. This includes the disk type itself, for a more complete consistency. Note that since in the Python code-base there's no authoritative place where we document the logical id, this is probably a good reference point. There is a bijective correspondence between the DiskLogicalId constructors and DiskTemplate.

Constructors

LIDPlain LogicalVolume	Volume group, logical volume
LIDDrbd8 String String Int Int Int (Private DRBDSecret)	NodeA, NodeB, Port, MinorA, MinorB, Secret
LIDFile FileDriver String	Driver, path
LIDSharedFile FileDriver String	Driver, path
LIDGluster FileDriver String	Driver, path
LIDBlockDev BlockDriver String	Driver, path (must be under /dev)
LIDRados String String	Unused, path
LIDExt String String	ExtProvider, unique name

Instances

Eq DiskLogicalId
Show DiskLogicalId
Arbitrary DiskLogicalId

lidDiskType :: DiskLogicalId -> DiskTemplate Source

Mapping from a logical id to a disk type.

lidEncodeType :: DiskLogicalId -> [(String, JSValue)]Source

Builds the extra disk_type field for a given logical id.

encodeDLId :: DiskLogicalId -> JSValueSource

Custom encoder for DiskLogicalId (logical id only).

encodeFullDLId :: DiskLogicalId -> (JSValue, [(String, JSValue)])Source

Custom encoder for DiskLogicalId, composing both the logical id and the extra disk_type field.

decodeDLId :: [(String, JSValue)] -> JSValue -> Result DiskLogicalId Source

Custom decoder for DiskLogicalId. This is manual for now, since we don't have yet automation for separate-key style fields.

data Disk Source

Disk data structure.

Constructors

RealDisk RealDiskData
ForthcomingDisk ForthcomingDiskData

Instances

Eq Disk
Show Disk
JSON Disk
ArrayObject Disk
DictObject Disk
SerialNoObject Disk
ForthcomingObject Disk
UuidObject Disk
TimeStampObject Disk
SerialNoObjectL Disk
UuidObjectL Disk
TimeStampObjectL Disk
Arbitrary Disk	`Disk` `arbitrary` instance. Since we don't test disk hierarchy properties, we only generate disks with no children (FIXME), as generating recursive datastructures is a bit more work.

includesLogicalId :: LogicalVolume -> Disk -> BoolSource

Determines whether a disk or one of his children has the given logical id (determined by the volume group name and by the logical volume name). This can be true only for DRBD or LVM disks.
