Brian Behlendorf, anotungamira ZFS mugadziri paLinux, yakaburitswa mavhiki mashoma apfuura iyo nyowani vhezheni 2.0 yeOpenZFS mune yako GitHub account.
Iyo ZFS chirongwa paLinux yava kunzi OpenZFS uye mune iyi nyowani vhezheni 2.0 Linux neFreeBSD zvino zvatsigirwa ine imwecheteyo repository, ichiita kuti ese maOpenZFS maficha awanikwe pamapuratifomu ese ari maviri.
Inowanzozivikanwa ZFS nenharaunda yako senge OpenZFS yakavhurika sosi fileystem ine CDDL rezinesi (Zvakajairika kuvandudza uye kugovera rezinesi)
Inoshandiswa mukushandisa masisitimu akadai se: FreeBSD, Mac OS X 10.5 uye Linux kugoverwa, Inozivikanwa nehukuru hwayo hwekuchengetedza. Iyo yakapusa uye yakapusa faira sisitimu yekumisikidza kuchengetedza manejimendi mapuratifomu.
VhuraZFS chingave chiri chirongwa chekuunza vanhu nemakambani pamwechete uchishandisa ZFS faira system uye ivo vari kushanda kuti vavandudze. Izvi ndezvekuita ZFS inozivikanwa uye kuivandudza munzira yakavhurika sosi. OpenZFS inounza pamwechete vanogadzira kubva kumalumos, Linux, FreeBSD uye macOS mapuratifomu, chirongwa ichi chinounza pamwechete akasiyana makambani.
Nezve iyo nyowani vhezheni 2.0
Chimwe chezvinhu zvinokwezva zveZFS ndeye yakadzika kuverenga cache, inozivikanwa seARC. ARC Level 2 Persistence (L2ARC) inoitwa nekupota kunyora metadata kune iyo L2ARC mudziyo kubvumidza iyo L2ARC buffer musoro zvinyorwa kuti zvidzorerwe kuARC painounza dziva kana kuunza L2ARC chishandiso pamhepo, kudzikisira kukanganisa yekuchengetedza system performance downtime. Naizvozvo, ZFS inozivikanwa faira sisitimu yekuchengetedza mapuratifomu.
Masystem ane makuru kwazvo seti emabasa anogona zvakare kushandisa SSD-based kuverenga cache, inonzi L2ARC, iyo inozadza kubva pamabhureki eARC kuburitswa.
Nhoroondo, rimwe rematambudziko makuru neL2ARC nderekuti kunyangwe iyo iri pasi peSSD ichiramba, iyo L2ARC pachayo haina; inoenda isina chinhu nguva dzese paunotangazve (kana kutumira kunze uye kupinza kubva kuboka). Aya mashandiro matsva anotendera data reL2ARC kuti rirambe richiwanika uye richikwanisa kushanda pakati peboka rekupinza / kutumira kunze masekonzi (kusanganisira system reboots), ichiwedzera zvakanyanya kukosha kungavepo kwechishandiso cheL2ARC.
Imwe nzira itsva yeiyi vhezheni itsva yeOpenZFS 2.0 ndeyekuti inopa yakakwana inline compression, sezvo iyo Zstd compression algorithm (pachinyakare iyo inonyanya kushandiswa algorithm iri lz4) inopa yakaderera compression ratio, asi yakareruka CPU mutoro. OpenZFS 2.0.0 inopa rutsigiro rwe zstd, algorithm yakagadzirirwa naYann Collet (munyori we lz4) iyo inotarisira kupa compression yakafanana ne gzip, iine CPU mutoro wakafanana ne lz4.
Kana uchimanikidza (kunyorera kudiski), zstd-2 ichiri kushanda zvakanyanya kupfuura gzip-9 ichiri kuita yakakwira kuita. Mukuenzanisa ne lz4, zstd-2 inozadzisa makumi mashanu kubva muzana kumanikidza mukutsinhana ne30% kurasikirwa mukuita. Kana zviri zvekudzikisira (disc kutamba), iyo bit rate iri yakati kwirei zvishoma, kutenderedza 36%.
Kuwedzera kune akakosha maficha akatsanangurwa pamusoro, OpenZFS 2.0.0 maficha akarongedzwa uye akavandudzwa mapeji emurume, naizvozvowo zvakanyanya kuvandudza mashandiro kana uchiparadza, kutumira uye kugamuchira zfs uye inoshanda zvakanyanya memory memory uye yakanyatsogadziriswa encryption performance.
Imwe shanduko yakakosha ndeyekuti iwo murairo wakateedzana nzira yekuuraya yakaitwa Resilver (yakateedzana resilver), iyo inogadzirisazve kugovera dhata ichifunga nezve shanduko mukugadzirisa dhiraivha.
Iyo nzira nyowani inobvumira kuvaka patsva vdev girazi nekukurumidza zvakanyanya pane kudzora kwechinyakare: kutanga, iyo yakarasika redundancy mune yakarongeka inodzoreredzwa nekukurumidza sezvazvinogona, uye ipapo chete ndipo "kuchenesa" mashandiro otomatiki anotanga kuongorora ese ma data cheki.
Iyo nyowani modhi inotanga kana iwe ukawedzera kana kutsiva dhiraivha nemirairo «zpool kutsiva | batanidza "ne" -s "sarudzo.
Finalmente kana iwe uchifarira kuziva zvakawanda nezvazvo yeiyi vhezheni itsva, unogona kutarisa iyo ruzivo mune inotevera chinongedzo.
