Method Details [hide private]

__init__(self, anaconda=None, intf=None, platform=None)
(Constructor)

source code  
Create a Storage instance.

Keyword Arguments:

    anaconda    -   an Anaconda instance
    intf        -   an InstallInterface instance
    platform    -   a Platform instance

All arguments are optional. An Anaconda instance will contain
an InstallInterface and a Platform instance, so it makes sense
to pass in either an Anaconda instance or as many of the other
two as is desired. Explicitly passed intf or platform will take
precedence over those in the Anaconda instance.
Overrides: object.__init__

nextID(self)

source code 
Decorators:
  • @property

reset(self, cleanupOnly=False)

source code 

Reset storage configuration to reflect actual system state.

This should rescan from scratch but not clobber user-obtained information like passphrases, iscsi config, &c

devices(self)

source code 

A list of all the devices in the device tree.

Decorators:
  • @property

disks(self)

source code 

A list of the disks in the device tree.

Ignored disks are not included, as are disks with no media present.

This is based on the current state of the device tree and does not necessarily reflect the actual on-disk state of the system's disks.

Decorators:
  • @property

partitioned(self)

source code 

A list of the partitioned devices in the device tree.

Ignored devices are not included, nor disks with no media present.

Devices of types for which partitioning is not supported are also not included.

This is based on the current state of the device tree and does not necessarily reflect the actual on-disk state of the system's disks.

Decorators:
  • @property

partitions(self)

source code 

A list of the partitions in the device tree.

This is based on the current state of the device tree and does not necessarily reflect the actual on-disk state of the system's disks.

Decorators:
  • @property

vgs(self)

source code 

A list of the LVM Volume Groups in the device tree.

This is based on the current state of the device tree and does not necessarily reflect the actual on-disk state of the system's disks.

Decorators:
  • @property

lvs(self)

source code 

A list of the LVM Logical Volumes in the device tree.

This is based on the current state of the device tree and does not necessarily reflect the actual on-disk state of the system's disks.

Decorators:
  • @property

pvs(self)

source code 

A list of the LVM Physical Volumes in the device tree.

This is based on the current state of the device tree and does not necessarily reflect the actual on-disk state of the system's disks.

Decorators:
  • @property

mdarrays(self)

source code 

A list of the MD arrays in the device tree.

This is based on the current state of the device tree and does not necessarily reflect the actual on-disk state of the system's disks.

Decorators:
  • @property

mdcontainers(self)

source code 

A list of the MD containers in the device tree.

Decorators:
  • @property

mdmembers(self)

source code 

A list of the MD member devices in the device tree.

This is based on the current state of the device tree and does not necessarily reflect the actual on-disk state of the system's disks.

liveImage(self)

source code 

The OS image used by live installs.

exceptionDisks(self)

source code  
Return a list of removable devices to save exceptions to.

FIXME: This raises the problem that the device tree can be
       in a state that does not reflect that actual current
       state of the system at any given point.

       We need a way to provide direct scanning of disks,
       partitions, and filesystems without relying on the
       larger objects' correctness.

       Also, we need to find devices that have just been made
       available for the purpose of storing the exception
       report.

deviceImmutable(self, device, ignoreProtected=False)

source code 

Return any reason the device cannot be modified/removed.

Return False if the device can be removed.

Devices that cannot be removed include:

  • protected partitions
  • devices that are part of an md array or lvm vg
  • extended partition containing logical partitions that meet any of the above criteria

createDevice(self, device)

source code  
Schedule creation of a device.

TODO: We could do some things here like assign the next
      available raid minor if one isn't already set.

mustFormat(self, device)

source code 

Return a string explaining why the device must be reformatted.

Return None if the device need not be reformatted.

safeDeviceName(self, name)

source code 

Convert a device name to something safe and return that.

LVM limits lv names to 128 characters. I don't know the limits for the other various device types, so I'm going to pick a number so that we don't have to have an entire fucking library to determine device name limits.

doEncryptionPassphraseRetrofits(self)

source code 

Add the global passphrase to all preexisting LUKS devices.

This establishes a common passphrase for all encrypted devices in the system so that users only have to enter one passphrase during system boot.

sanityCheck(self)

source code 

Run a series of tests to verify the storage configuration.

This function is called at the end of partitioning so that we can make sure you don't have anything silly (like no /, a really small /, etc). Returns (errors, warnings) where each is a list of strings.

bootDevice(self)

source code 
Decorators:
  • @property

bootLoaderDevice(self)

source code 
Decorators:
  • @property

bootFSTypes(self)

source code 

A list of all valid filesystem types for the boot partition.

Decorators:
  • @property

defaultBootFSType(self)

source code 

The default filesystem type for the boot partition.

Decorators:
  • @property

mountpoints(self)
