Apr\u00e8s un an de d\u00e9veloppement publi\u00e9e<\/a><\/noindex> lancement du projet Stratis 2.0<\/a><\/noindex>, d\u00e9velopp\u00e9 par la soci\u00e9t\u00e9 Red Hat et la communaut\u00e9 Fedora pour unifier et simplifier les outils de configuration et de gestion d'un pool d'un ou plusieurs supports de stockage locaux. Stratis offre des fonctionnalit\u00e9s telles que l'allocation dynamique d'espace de stockage, des snapshots, l'assurance d'int\u00e9grit\u00e9 et la cr\u00e9ation de couches pour la mise en cache. Le code du projet est \u00e9crit en Rust et est distribu\u00e9<\/a><\/noindex> sous licence MPL 2.0.<\/p>\n

Le syst\u00e8me reproduit en grande partie les fonctionnalit\u00e9s des outils avanc\u00e9s de gestion de partitions ZFS et Btrfs, mais est r\u00e9alis\u00e9 sous la forme d'une couche (daemon stratisd<\/a><\/noindex>), fonctionnant au-dessus de la sous-syst\u00e8me device-mapper du noyau Linux (utilisant des modules dm-thin, dm-cache, dm-thinpool, dm-raid et dm-integrity) et le syst\u00e8me de fichiers XFS. Contrairement \u00e0 ZFS et Btrfs, les composants de Stratis fonctionnent uniquement en espace utilisateur et ne n\u00e9cessitent pas le chargement de modules sp\u00e9cifiques au noyau. Le projet est initialement pr\u00e9sent\u00e9 comme ne n\u00e9cessitant pas<\/a><\/noindex> des qualifications d'expert en syst\u00e8mes de stockage pour son administration. <\/p>\n

Pour la gestion, une API D-Bus est fournie et un utilitaire cli<\/a><\/noindex>.
\nLe fonctionnement de Stratis a \u00e9t\u00e9 test\u00e9 avec des dispositifs de blocs bas\u00e9s sur LUKS (partitions chiffr\u00e9es), mdraid, dm-multipath, iSCSI, volumes logiques LVM, ainsi qu'avec divers disques durs, SSD et dispositifs NVMe. Si le pool compte un seul disque, Stratis permet d'utiliser des partitions logiques avec support de snapshots pour revenir en arri\u00e8re. Lors de l'ajout de plusieurs supports au pool, il est possible de regrouper logiquement les supports en une zone continue. Des fonctionnalit\u00e9s telles que
\nRAID, la compression de donn\u00e9es, la d\u00e9duplication et la mise en place de tol\u00e9rance aux pannes ne sont pas encore prises en charge, mais sont pr\u00e9vues pour le futur.<\/p>\n

\"Lancement<\/a><\/noindex><\/center><\/p>\n

Dans nouvelle<\/a><\/noindex> version<\/a><\/noindex> des exigences accrues pour la version du compilateur Rust (au moins 1.37, mais 1.38 est recommand\u00e9). Un changement important dans le num\u00e9ro de version est d\u00fb au renommage de certaines interfaces D-Bus et \u00e0 la refonte de l'organisation du travail avec D-Bus (un ensemble de propri\u00e9t\u00e9s fondamentales primaires a \u00e9t\u00e9 d\u00e9fini, tandis que les autres propri\u00e9t\u00e9s sont d\u00e9sormais demand\u00e9es par un nouveau moyen FetchProperties).<\/p>\n
