Description

This interface provides information about a block device on a UNIX-like system. In addition to just providing information, methods can be invoked to perform operations on the block device. Objects implementing this interface have object paths prefixed with /devices/ followed by a sanitized representation of the base name of their native path. As the D-Bus specification greatly limits what characters can be used in object paths, this doesn't necessarily map one to one with the native basename; for example the native path /sys/devices/virtual/block/dm-0 will be represented as /devices/dm_0.

Most methods on this interface take an array of strings for options that can affect what the method does. Some of these options are literal strings (such as noatime) while some are encoded in the form of a key/value pair (such as label=).

A general note about properties: the set of values returned can be expected to grow in the future as both hardware and operating system capabilities evolve. Care has been taken to namespace values so applications can properly fall back (see e.g. drive-media-compatibility) and export both general and specific properties (such as id-usage vs. id-type). In general an empty string in a property means not set. Since the empty string is not a valid object path we use the "/" to mean "not set" for object paths.

The "linux-md-home-host" property

'linux-md-home-host'  read      's'

The home host of the array, e.g. where if was created. Blank if the array has pre-1.0 meta data. device-is-linux-md is TRUE.

The "linux-md-name" property

'linux-md-name'  read      's'

The name of the array. Blank if the array doesn't have a name (e.g. pre-1.0 meta data). device-is-linux-md is TRUE.

The "linux-md-num-raid-devices" property

'linux-md-num-raid-devices'  read      'i'

Number of component devices in the array. This property is only valid if device-is-linux-md is TRUE.

The "linux-md-version" property

'linux-md-version'  read      's'

Metadata version used in the components. This property is only valid if device-is-linux-md is TRUE.

The "linux-md-slaves" property

'linux-md-slaves'  read      'ao'

An array of object paths for components currently part of the array. This property is only valid if device-is-linux-md is TRUE.

The "linux-md-is-degraded" property

'linux-md-is-degraded'  read      'b'

TRUE only if the array is running in degraded mode. This property is only valid if device-is-linux-md is TRUE.

The "linux-md-sync-action" property

'linux-md-sync-action'  read      's'

  • idle: No operation is pending
  • reshape: A reshape is in progress
  • resync: Redudancy is being calculated
  • repair: A repair operation is in progress
  • recover: A hot spare is being built to replace a failed/missing device

This property is only valid if device-is-linux-md is TRUE.

The "linux-md-sync-percentage" property

'linux-md-sync-percentage'  read      'd'

The progress of the current sync operation. This property is only valid if device-is-linux-md is TRUE and the value of the property linux-md-sync-action is not idle.

The "linux-md-sync-speed" property

'linux-md-sync-speed'  read      't'
