Dans la base de code \u00abZFS sur Linux<\/a><\/noindex>\u00bb, d\u00e9velopp\u00e9e sous l'\u00e9gide du projet OpenZFS<\/a><\/noindex> en tant qu'impl\u00e9mentation de r\u00e9f\u00e9rence de ZFS, ont \u00e9t\u00e9 adopt\u00e9es<\/a><\/noindex> des modifications ajoutant le support<\/a><\/noindex> du syst\u00e8me d'exploitation FreeBSD. Le code ajout\u00e9 dans \u00abZFS on Linux\u00bb a \u00e9t\u00e9 test\u00e9 dans les branches FreeBSD 11 et 12. Ainsi, les d\u00e9veloppeurs de FreeBSD n'ont plus besoin de maintenir leur propre branche synchronis\u00e9e de \u00abZFS on Linux\u00bb et le d\u00e9veloppement de tous les changements li\u00e9s \u00e0 FreeBSD sera r\u00e9alis\u00e9 dans le projet principal. De plus, la fonctionnalit\u00e9 de la branche principale \u00abZFS on Linux\u00bb sous FreeBSD sera test\u00e9e dans un syst\u00e8me d'int\u00e9gration continue. <\/p>\n

Rappelons qu'en d\u00e9cembre 2018, les d\u00e9veloppeurs de FreeBSD ont propos\u00e9 une initiative<\/a><\/noindex> le passage \u00e0 l'impl\u00e9mentation de ZFS du projet \u00abZFS sur Linux<\/a><\/noindex>\u00bb (ZoL), autour duquel toute l'activit\u00e9 r\u00e9cente li\u00e9e au d\u00e9veloppement de ZFS s'est concentr\u00e9e. La stagnation de la base de code ZFS du projet Illumos (un fork d'OpenSolaris), qui \u00e9tait auparavant utilis\u00e9e comme base pour le transfert des changements li\u00e9s \u00e0 ZFS dans FreeBSD, a \u00e9t\u00e9 mentionn\u00e9e comme raison de la migration. La principale contribution au soutien de la base de code ZFS dans Illumos a \u00e9t\u00e9 fournie jusqu'\u00e0 r\u00e9cemment par la soci\u00e9t\u00e9 Delphix, qui d\u00e9veloppe le syst\u00e8me d'exploitation DelphixOS<\/a><\/noindex> (fork d'Illumos). Il y a deux ans, Delphix a d\u00e9cid\u00e9 de passer \u00e0 \u00abZFS on Linux\u00bb, ce qui a conduit \u00e0 la stagnation de ZFS du projet Illumos et \u00e0 la concentration de toute l'activit\u00e9 de d\u00e9veloppement dans le projet \u00abZFS on Linux\u00bb, qui est d\u00e9sormais consid\u00e9r\u00e9 comme l'impl\u00e9mentation principale. OpenZFS<\/a><\/noindex>.<\/p>\n

Les d\u00e9veloppeurs de FreeBSD ont d\u00e9cid\u00e9 de suivre l'exemple g\u00e9n\u00e9ral et de ne pas s'accrocher \u00e0 Illumos, car cette impl\u00e9mentation est d\u00e9sormais fortement en retard en termes de fonctionnalit\u00e9s et n\u00e9cessite des ressources consid\u00e9rables pour le maintien du code et le transfert des changements. \u00abZFS on Linux\u00bb est d\u00e9sormais consid\u00e9r\u00e9 comme le projet commun principal pour le d\u00e9veloppement de ZFS. Parmi les possibilit\u00e9s disponibles dans \u00abZFS on Linux\u00bb pour FreeBSD, mais absentes dans l'impl\u00e9mentation ZFS d'Illumos : le mode multih\u00f4te (\"MMP<\/a><\/noindex>, Protection de Multi Modificateur), un syst\u00e8me de quotas avanc\u00e9, le chiffrement des ensembles de donn\u00e9es, un choix s\u00e9par\u00e9 des classes d'allocation (allocation classes), l'utilisation d'instructions de processeur vectoriel pour acc\u00e9l\u00e9rer l'impl\u00e9mentation de RAIDZ et le calcul des sommes de contr\u00f4le, des outils de ligne de commande am\u00e9lior\u00e9s, et la correction de nombreux bugs li\u00e9s aux conditions de course et aux blocages.<\/p>\n
