Anaconda Storage Rewrite
This is the main page for information about anaconda's pending storage rewrite. The entire storage subsystem is being rewritten from scratch. This is long overdue.
Motivation
Anaconda's device management, filesystem management, and partitioning code are all intertwined in a confusing mess. This code is comprised largely of custom software. As new and complex storage paradigms arise this code gets more and more convoluted. It is time to redesign with an eye toward extensibility and maintainability, to the extent that this is possible in the long term. It is also a potential opportunity to integrate some pieces of the post-install system into the installation environment so that users experience consistent behavior.
Tasks
The following tasks have been identified:
- create python bindings for critical utilities
- pyparted
- rewrite
- dcantrell, clumens
- libdevmapper (device-mapper)
- python bindings for libdevmapper
- wrapper module in python if needed
- hansg, jgranados
- iscsiadm (iscsi-initiator-utils)
- Write a small library to expose iscsi-initiator-utils functionality in a sane manner: API proposal
- python bindings for libiscsi
- hansg
- cryptsetup (cryptsetup-luks)
- python bindings for libcryptsetup and wrapper module in python (or equivalent of cryptsetup entry points)
- msivak
- Basic python library for cryptsetup entrypoints is ready
- temporary git repo is at http://msivak.fedorapeople.org/git/pycryptsetup.git/
- gitweb lives at http://fedorapeople.org/gitweb?p=msivak/public_git/pycryptsetup.git;a=summary
- The cryptsetup API needs rewrite to enable more advanced stuff and extensibility (updating the keys, safe partition formatting, ...) and to be thread-safe.
- mdadm
- python bindings for equivalent of cmdline entry points (or library, bindings, and wrapper module if feasible)
- rvykydal
- notes and status after mail exchange with Doug Ledford
- liblvm (lvm2?)
- library is still in early development. Here is the project page.
- python bindings for library, and a python wrapper module if needed
- twoerner, along with others from lvm team
- pyparted
- design/develop anaconda storage subsystem
- device discovery and/or management subsystem
- dlehman
- internal representations of devices, filesystems, &c
- interfaces to external libraries, utilities described above
- dlehman
- integration layer
- partitioning
- dlehman
- filesystem management
- dcantrell, dlehman
- kickstart
- clumens, dlehman
- transactional model to interface with the UI layer
- clumens, dcantrell
- partitioning
- user interface
- an external UI designer, hopefully (mizmo?)
- clumens, dcantrell
- device discovery and/or management subsystem
Design Documents
Here is a quick mock-up of a design diagram.
Here is a first crack at visualizing the flow of storage-related portions of anaconda: High-level storage flow
Diagram of block device scanning procedure.
TODO
- make a schedule
- generate some (very rough) design documents
