Mushure memakore angangoita maviri ekuvandudza, kuburitswa kweZFS paLinux 0.8.0 kunoratidzwa, iko kuiswa kweZFS faira system, yakagadzirirwa senge module yeLinux kernel.
Sechikamu cheZFS paLinux, kuiswa kwezvikamu zveZFS kwakagadzirirwa ayo anoenderana neese ari maviri mafaera system mashandiro uye nevhoriyamu maneja mashandiro Kunyanya inoitwa zvinotevera zvinhu: SPA (Storage Pool Allocator), DMU (Data Management Unit), ZVOL (ZFS Yakatemerwa Vhoriyamu), uye ZPL (ZFS POSIX Layer).
Uyewo, Iyo purojekiti yakapa kugona kushandisa ZFS senge backend yeLuster cluster faira system.
Iyo projekiti hwaro hwakavakirwa pane yekutanga ZFS kodhi yakatumirwa kubva kuOpenSolaris projekiti uye inowedzeredzwa nezvigadziriso uye zvigadziriso kubva munharaunda yeIllumos. Iyo purojekiti iri kuvandudzwa nekutora kwevashandi veLivermore National Laboratory pasi pechibvumirano neUnited States Department of Energy.
Iyo kodhi inogoverwa pasi peirisense remahara reCDDL, izvo zvisingawirirane neGPLv2, iyo isingatenderi kusangana kweZFS paLinux kupinda muLinux kernel huru, sezvo kusanganiswa kwemakodhi ari pasi peGPLv2 neCDDL marezinesi hakugamuchirwe.
Kuti udzivise kusaenderana kwekupa marezinesi, zvakatemwa kugovera chigadzirwa zvachose pasi peCDDL rezinesi seyakasiyana inotakurika module, inotumirwa zvakasiyana kubva kune kernel. Iko kudzikama kweiyo ZFS kodhi base paLinux inofungidzirwa kuti ingaenzaniswe nemamwe mafaera masisitimu eLinux.
Iyo module yakaedzwa neLinux kernels kubva 2.6.32 kusvika 5.1. Kugadzirira kuisirwa mapakeji kuchakurumidza kugadzirirwa kugoverwa kukuru kweLinux kusanganisira Debian, Ubuntu, Fedora, RHEL / CentOS.

Sechikamu cheshanduko chakawedzerwa mukuburitswa iwe unogona kuwana iyo yakavakirwa-mukati yekutsigira kunyorera data yakachengetwa pakakamurwa uye faira system nhanho. Iyo yakasarudzika encryption algorithm ndeye aes-256-ccm. Kuisa makiyi ekuvharira, rairo "zfs mutoro-kiyi" inokurudzirwa.
Saizvozvowo iko kugona kwekutamisa yakavharidzirwa data kunoitwa nekuita iyo mirairo 'Zfs tumira' uye 'zf gamuchira'.
Kana iyo »-w« sarudzo yataurwa, iyo data yatove yakanyorwa mukati meboka ichiendeswa kune rimwe boka sezvazviri, pasina dhizaini yepakati iyo inobvumidza iwe kushandisa iyi modhi kutsigira zvisina kuvimbika masystem (kuitira kuti anenge achigamuchira abvuma, pasina kiyi , anorwisa haazokwanise kuwana iyo data).
Uyewo rutsigiro rweakafanana block basa rekuita rakawedzerwa kuburikidza nekuitwa kweakasiyana "mugove" maitiro eimwe seti yemasaslabs.
Mune echinyakare masisitimu, kune kuwedzera kwekuita kwe5 kusvika 10%, asi mune makuru (8,128 GB SSD, 24 NUMA musimboti, 256 GB RAM), kuwedzera kwemabasa ekugovanisa block kunogona kusvika 25%.
Imwe nzira yekuratidzira ndeye iko kugona kwekugadzira Lua zvinyorwa zvekumisikidza akasiyana mabasa neZFS. Iwo ma script anomhanyisa mune akakosha sandboxes vachishandisa iyo "zpool chirongwa" kuraira.
Nezve izvi zvakauyawo rutsigiro rwekuverenga uye zviga padanho reprojekti, zvichizadzisa zviga zvaimbove zviripo padanho revashandisi neboka.
Mukukosha, mapurojekiti chinhu chakaparadzaniswa chinzvimbo chakabatana nechakasiyana chiziviso (chirongwa ID).
Chekupedzisira, dzimwe shanduko dzinomira pachena ndedzekuti kuita kwekugadzirisa kunoratidzwa:
- Iyo yekukwesha neye resilver mirairo inomhanyiswa nekuda kwekukamurwa kuita zvikamu zviviri (chikamu chakaparadzaniswa chakapihwa kuongorora metadata uye kuona nzvimbo yemabhuroko nedata pane diski, ichibvumira kumwe kuongorora nekuteedzana kuverenga kwedata).
- Tsigiro yemakirasi ekugovera dhata (makirasi ekugovera), ayo anotendera iwe kuti ubatanidze madiki maSDD mudziva uye uashandise kuchengeta chete mamwe marudzi emabhuroko anoshandiswa kazhinji, senge metadata, DDT dhata, uye zvidiki zvidhinha zvine mafaera.
- Iko mashandiro ehutongi mirairo yakadai se "zfs rondedzero" uye "zfs tora" yakagadziridzwa nekuchengetedza metadata inodikanwa pabasa ravo.
