BTRFS di Fedora 17 file system predefinito

Sommario

Rendere BTRFS il file system predefinito per installazioni normali.

Manutentore

Descrizione dettagliata

Rendere BTRFS il file system predefinito per nuove installazioni di Fedora, ed uso delle capacità di gestione di volume, integrate in BTRFS, al posto di LVM.

Vantaggi per Fedora

BTRFS include molte caratteristiche non presenti in altri file system, altamente apprezzati dai normali utenti, tra cui:

Checksumming
Snapshotting
Gestione volumi integrato e RAID

Il checksumming offre agli utenti migliore integrità dei dati, e lo snapshotting permette di fare cose come prendere snapshot del file system prima di fare cose potenzialmente dannose, come gli aggiornamenti via yum, in modo da avere uno stato a cui fare roll back.

Scope

Anaconda - not terribly important but would be good to expose some of the different features of BTRFS via anaconda.
- Subvolume support (for /home by default)
- Optional compression
- RAID support
- Ext3/4 conversion
LiveCD tools - these would need to be reworked to create a BTRFS image to install with.

How To Test

It should be simple enough to test, just do a normal install. If Anaconda gets support for the different BTRFS capabilities we'd want to test a couple of cases

Single disk BTRFS
Multi-disk BTRFS, RAID0/1/10
Creating different subvolumes in the install

Esperienza utente

Il cambiamento dovrebbe essere largamente invisibile agli utenti. Questi potranno trarre vantaggio dalle varie caratteristiche messe a disposizione di BTRFS.

Dependencies

Anaconda
LiveCD tools

Contingency Plan

We can just keep ext4 as the default installed file system.

Note di rilascio

Al momento non c'è niente da specificare altro che si illumina la strada del cambiamento.

-Checksumming give our users better data integrity, and snapshotting allows us to do thing's like take snapshots of the file system before doing potentially dangerous things, like yum updates, in order to provide a position to roll back to.
