OpenZFS 2.0.0

Kusintha kwakukulu pamafayilo ndi zida zake zokonzera, OpenZFS 2.0.0, kwatulutsidwa. Mtundu watsopanowu umathandizira ma kernels a Linux kuyambira 3.10 ndi ma kernels a FreeBSD kuyambira mtundu 12.2, ndipo kuphatikiza pa izi, tsopano akuphatikiza ma code a machitidwe onse awiri m'malo amodzi. Pakati pa kusintha kwakukulu, opanga amawona izi:

  • Anawonjezera kuthekera kotsatizana (LBA) kumanganso gulu lowonongeka la Mirror vDev RAID. Njirayi ndi yofulumira kwambiri kuposa kuchira kwachikhalidwe "kuchiritsa". Komabe, sichiyang'ana ma checksums blocksums, chifukwa chake atangomaliza, sitepe yotsatira ndikuyambitsa kufufuza kwaumphumphu (kutsuka).

  • Kubwezeretsanso cache ya L2ARC pambuyo poyambitsanso dongosolo. Cache yokha imagwiritsa ntchito kuchuluka kwa RAM, osagwiritsa ntchito hard drive yocheperako kuti mupeze deta pafupipafupi. Tsopano mutatha kuyambiranso deta ya cache ya L2ARC idzakhalapo.

  • Thandizo la psinjika mu mtundu wa ZStandard, womwe umapereka mulingo wa psinjika wofanana ndi GZIP, koma nthawi yomweyo magwiridwe antchito apamwamba kwambiri. Kuti zikhale zosavuta, woyang'anira amapatsidwa mwayi wosankha mulingo woponderezedwa kuti atsimikizire bwino pakati pa magwiridwe antchito ndi kupulumutsa malo a disk.

  • Kutha kusankha deta posamutsa pogwiritsa ntchito kutumiza/kulandira malamulo. Tsopano oyang'anira atha kuchotsa pamanja deta yosafunikira kapena yachinsinsi pakusamutsa asanakopere chithunzithunzi.

  • Zina zambiri, zosafunikira kwenikweni, koma zosintha zosasangalatsa zakhazikitsidwa, makamaka, pam module yalembedwa potsitsa makiyi afoda, masamba amunthu adakonzedwanso ndipo zolembedwa zasinthidwa, anawonjezera zfs voliyumu mount jenereta ya systemd, kukulitsa mitengo mu syslog, kugwirizanitsa bwino ndi ma bootloaders a system, ndi zina zambiri.

  • Malamulo atsopano ndi makiyi awonjezedwa kwa omwe alipo kale, omwe mungawerenge zambiri ndemanga zazifupi za kumasulidwa.

  • Zida zingapo zamkati zakhala zokongoletsedwa molingana ndi liwiro komanso kugwiritsa ntchito moyenera zinthu zamadongosolo.

Kusintha kwathunthu.
