De nieuwe versie ondersteunt Linux-kernen vanaf 3.10 en FreeBSD vanaf versie 12.2, en voegt bovendien de code voor beide besturingssystemen samen in \u00e9\u00e9n enkele repository. Onder de belangrijkste wijzigingen vermelden de ontwikkelaars de volgende punten:<\/p>\n<ul>\n<li>\n<p>De mogelijkheid voor sequenti\u00eble (LBA) reconstructie van een beschadigde RAID-mirror vDev-array is toegevoegd. Dit mechanisme is veel sneller dan traditionele herstelmethoden. Echter, het mist de controle van de checksum van de blokken, waardoor onmiddellijk na de afronding de volgende stap een integriteitscontrole van het systeem (scrub) wordt uitgevoerd.<\/p>\n<\/li>\n<li>\n<p>Herstel van L2ARC-cache na herstart van het systeem. De cache maakt gebruik van een toegewezen hoeveelheid RAM, zonder de langzamere harde schijf te gebruiken bij frequente gegevensverzoeken. Nu zullen na een herstart de gegevens van de L2ARC-cache intact blijven.<\/p>\n<\/li>\n<li>\n<p>Ondersteuning voor compressie in het ZStandard-formaat, dat een compressieniveau biedt dat vergelijkbaar is met GZIP, maar met veel hogere prestaties. Voor het gemak heeft de beheerder de mogelijkheid om het compressieniveau te kiezen voor de beste balans tussen prestaties en ruimtebesparing op de schijf.<\/p>\n<\/li>\n<li>\n<p>De mogelijkheid om gegevens te selecteren tijdens het verplaatsen met de send\/receive-commando's. Beheerders kunnen nu handmatig ongewenste of priv\u00e9-gegevens uitsluiten van de overdracht voordat ze een snapshot kopi\u00ebren.<\/p>\n<\/li>\n<li>\n<noindex><noindex><\/p>\n<p>Er zijn veel andere, minder ingrijpende, maar evenzeer aangename verbeteringen doorgevoerd, waaronder de ontwikkeling van een pam-module voor het laden van versleutelingssleutels van mappen, reorganisatie van de man-pagina's en <a rel=\"nofollow\" href=\"https:\/\/openzfs.github.io\/openzfs-docs\/\">geactualiseerde documentatie<\/a>, toegevoegd een generator voor het monteren van zfs-volumes voor systemd, uitgebreid logging in syslog, verbeterde compatibiliteit met systeembootloaders en nog veel meer.<\/p>\n<p><\/noindex><\/noindex>\n<\/li>\n<li>\n<noindex><\/p>\n<p>Nieuwe commando's en sleutels aan
