Mushure megore nehafu yekuvandudza, OpenZFS 2.0 chirongwa chakatangwa iyo inovandudza kuiswa kweZFS faira system yeLinux uye FreeBSD.
Iyo purojekiti yakazozivikanwa se "ZFS paLinux" uye pakutanga zvaive zvakaganhurirwa mukugadzira module yeLinux kernel, asi mushure mekuchinjirwa kwerutsigiro rweFreeBSD, yakaonekwa seyekutanga OpenZFS kuita uye yakabviswa kubva pakataurwa nezveLinux muzita. Zvese zviitiko zvekuvandudza zveZFS zveLinux neBSD masisitimu izvo zvino zvatariswa muchirongwa chimwe uye zvakagadzirwa mune yakajairwa repositi.
VhuraZFS yatoshandiswa muFreeBSD kumusoro (MUSORO) uye inosanganisirwa neDebian, Ubuntu, Gentoo, Sabayon Linux, uye ALT Linux kugoverwa. Mapakeji neshanduro nyowani achakurumidza kugadzirira kugoverwa kukuru kweLinux, kusanganisira Debian, Ubuntu, Fedora, RHEL / CentOS.
MuFreeBSD, kodhi yacho inoenderana neiyo OpenZFS kodhi base zvazvino. OpenZFS yakaedzwa neLinux kernels 3.10 kusvika 5.9 (kernels inoenderana neyazvino vhezheni 2.6.32) uye iyo FreeBSD 12.2, yakagadzikana / 12 uye 13.0 (HEAD) matavi.
Nezve OpenZFS
VhuraZFS inopa kuiswa kwezvikamu yeZFS inoenderana neyese faira system uye nemaneja vhoriyamu. Zvikuru sei, zvinhu zvinotevera zvinoitwa: SPA (Storage Pool Allocator), DMU (Data Management Unit), ZVOL (ZFS Yakatemerwa Vhoriyamu) uye ZPL (ZFS POSIX Layer).
Uye zvakare, chirongwa icho oIyo inopa kugona kushandisa ZFS seye backend yeLuster yakaunganidzwa faira system. Basa reprojekti rakavakirwa pane yekutanga ZFS kodhi yakatumirwa kubva kuOpenSolaris projekiti uye inowedzeredzwa nezvigadziriso uye zvigadziriso kubva munharaunda yeIllumos Iyo purojekiti iri kuvandudzwa nekutora kwevashandi kubva kuLivermore National Laboratory pasi pechibvumirano neUnited States Department of Energy.
Iyo kodhi inogoverwa pasi pemahara rezinesi reCDDL, izvo zvisingawirirane neGPLv2, iyo isingatenderi kubatanidza OpenZFS mune yakakwira Linux kernel, nekuti hazvitenderwe kusanganisa kodhi pasi peGPLv2 neCDDL marezinesi. Kugadzirisa kusapindirana kwekupa marezinesi, zvakatemwa kugovera chigadzirwa chose pasi peCDDL rezenisi sedhiraivho yakadzikunurwa inotakurika yoga kubva kune kernel. Iko kudzikama kweiyo OpenZFS kodhi kodhi inoonekwa seyakaenzana neimwe FS yeLinux.
Main nyowani maficha eOpenZFS 2.0
Pane shanduko huru, iyo yakanyanya kumira ndeye tsigiro yeiyo FreeBSD chikuva uye kodhi yekodhi yakabatana kutsigira akasiyana masisitimu anoshanda. Dzese dzakabatana shanduko neFreeBSD izvozvi zviri kuvandudzwa mune huru OpenZFS repository uye chirongwa ichi chinoonekwa sekutanga kuitiswa kweZFS kweshanduro dzemberi dzeFreeBSD.
kunze kwaizvozvo kufambisa FreeBSD kuOpenZFS kwakabvisa akawanda mamiriro emujaho uye kukiya nyaya, uye kuunza maficha matsva kuFreeBSD, senge yakawedzera kota system, dhatabhesi encryption, makamuri ekugovera akasiyana, kushandiswa kwevector processor raira yekumhanyisa RAIDZ kuitisa uye checksum kuverenga, rutsigiro rweZSTD compression algorithm, yakawanda host mode ( MMP, Multiple Modifier Kudzivirirwa), uye yakagadziridzwa yekuraira maturu maturu
Imwe shanduko yakakosha ndeyekuti akateedzana maitiro ekuuraya akaitwa yeiyo "resilver" yekuraira (yakateedzana resilver), iyo inogadzirisazve kugoverwa kwedata uchifunga shanduko mukugadzirisa dhiraivha.
Iyo nzira nyowani inobvumira kuvaka patsva vdev girazi nekukurumidza zvakanyanya pane chinyakare chinodzorera. Iyo nyowani modhi inotanga kana iwe ukawedzera kana kutsiva dhiraivha nemirairo «zpool kutsiva | batanidza "ne" -s "sarudzo.
Yakaitwa inoramba yechipiri-chikamu cache (L2ARC), iyo data kubva pachigadzirwa chakabatanidzwa caching inochengetwa pakati pesystem reboots, ndiko kuti, cache mushure mekutanga inoramba iri "inopisa" uye mashandiro acho anosvika pamazita ehunhu, achipfuura yekutanga cache yekuzadza chikamu.
Yakawedzerwa tsigiro yeiyo zstd compression algorithm (Zstandard), iyo inoratidza ka3-5 nekukurumidza kumanikidza kumhanya uchienzaniswa ne-zlib / Deflate uye kaviri nekukurumidza kudzvinyirira, uku ichivandudza huwandu hwekumanikidza ne10-15%.
kunze kwaizvozvo kupa akasiyana siyana matanho ekumanikidza, Ivo vanopa chiyero chakasiyana pakati pekumanikidza kushanda uye kuita.
