La version 3.0 du projet Stratis, d\u00e9velopp\u00e9e par Red Hat et la communaut\u00e9 Fedora, a \u00e9t\u00e9 publi\u00e9e pour unifier et simplifier les outils de configuration et de gestion des pools d'un ou plusieurs disques locaux. Stratis offre des fonctionnalit\u00e9s telles que l'allocation dynamique de l'espace de stockage, des instantan\u00e9s, l'int\u00e9grit\u00e9 des donn\u00e9es et la cr\u00e9ation de couches de cache. Le support de Stratis est int\u00e9gr\u00e9 dans les distributions Fedora et RHEL \u00e0 partir de Fedora 28 et RHEL 8.2. Le code du projet est distribu\u00e9 sous la licence MPL 2.0. <\/p>\n

Le syst\u00e8me reproduit en grande partie les fonctionnalit\u00e9s des outils de gestion de partition avanc\u00e9s ZFS et Btrfs, mais a \u00e9t\u00e9 con\u00e7u comme une couche (d\u00e9mon stratisd) fonctionnant au-dessus du sous-syst\u00e8me device-mapper du noyau Linux (utilisant les modules dm-thin, dm-cache, dm-thinpool, dm-raid et dm-integrity) et du syst\u00e8me de fichiers XFS. Contrairement \u00e0 ZFS et Btrfs, les composants de Stratis fonctionnent uniquement dans l'espace utilisateur et ne n\u00e9cessitent pas le chargement de modules sp\u00e9cifiques au noyau. Le projet est initialement pr\u00e9sent\u00e9 comme n'exigeant pas de qualification d'expert en syst\u00e8mes de stockage pour l'administration. <\/p>\n

Un API D-Bus et une utilitaire cli sont fournis pour la gestion. Le fonctionnement de Stratis a \u00e9t\u00e9 test\u00e9 avec des dispositifs de blocs bas\u00e9s sur LUKS (partitions chiffr\u00e9es), mdraid, dm-multipath, iSCSI, des volumes logiques LVM, ainsi qu'avec diff\u00e9rents disques durs, SSD et unit\u00e9s NVMe. En cas de pr\u00e9sence d'un disque dans le pool, Stratis permet d'utiliser des partitions logiques avec support des instantan\u00e9s pour annuler des modifications. Lors de l'ajout de plusieurs p\u00e9riph\u00e9riques dans le pool, il est possible de combiner logiquement les disques en une zone continue. Des fonctionnalit\u00e9s telles que RAID, compression des donn\u00e9es, d\u00e9duplication et mise en place de la tol\u00e9rance aux pannes ne sont pas encore prises en charge, mais sont pr\u00e9vues pour l'avenir. <\/p>\n

\"Sortie<\/center> <\/p>\n

Le changement significatif de version s'explique par l'\u00e9volution de l'interface de gestion via D-Bus et l'abandon du support des interfaces FetchProperties au profit de propri\u00e9t\u00e9s et m\u00e9thodes bas\u00e9es sur D-Bus. La nouvelle version ajoute \u00e9galement la v\u00e9rification des r\u00e8gles udev \u00e0 l'aide de libblkid avant d'apporter des modifications, refond une gestion des \u00e9v\u00e9nements de DeviceMapper, modifie la repr\u00e9sentation interne des gestionnaires d'erreurs, repense le code pour le rollback, et permet de sp\u00e9cifier la taille logique lors de la cr\u00e9ation d'un syst\u00e8me de fichiers. Dans le framework Clevis, utilis\u00e9 pour le chiffrement et le d\u00e9chiffrement automatiques des donn\u00e9es sur les partitions de disque, des hachages SHA-256 sont employ\u00e9s \u00e0 la place de SHA-1. Il est d\u00e9sormais possible de changer la phrase de passe et de reg\u00e9n\u00e9rer les liaisons \u00e0 Clevis.
