Nws coj cov tsim tawm ntawm ZFS ntawm Linux (cov ntawv luv ZoL) txog ob xyoos thiab 5 RC tso tawm kom tso tawm qhov tseem ceeb tshaj plaws - ZFS-0.8.0.
ΠΠ²ΡΠ΅ Π²ΠΎΠ·ΠΌΠΎΠΆΠ½ΠΎΡΡΠΈ:
- "Native" encryption rau ob qho tib si cov ntaub ntawv systems thiab partitions. Lub neej ntawd algorithm yog aes-256-ccm. Cov yuam sij Dataset raug tswj xyuas siv "zfs load-key" hais kom ua thiab cov lus txib muaj feem xyuam.
- Encryption nrog zfs xa / txais. Tso cai rau koj khaws cov thaub qab ntawm cov kev pabcuam uas tsis ntseeg siab yam tsis muaj kev cuam tshuam.
- Tshem tawm ib lub cuab yeej los ntawm pas dej ua ke ntawm "zpool tshem tawm" hais kom ua. Tag nrho cov ntaub ntawv raug theej hauv keeb kwm yav dhau mus rau cov khoom siv sab saum toj kawg nkaus, thiab lub peev xwm ntawm lub pas dej tau txo qis raws li.
- "zpool checkpoint" subcommand tso cai rau koj txuag tag nrho lub xeev ntawm lub pas dej thiab, yog tias xav tau, rov qab mus rau lub xeev qhov tseeb. Qhov no tuaj yeem xav tias yog qhov txuas ntxiv ntawm lub pas dej. Qhov no yog qhov muaj txiaj ntsig zoo thaum ua cov thawj coj ua haujlwm nyuaj uas txwv tsis pub thim rov qab (xws li ua kom muaj qhov tshiab, rhuav tshem cov ntaub ntawv, thiab lwm yam)
- TRIM rau cov khoom siv pas dej ua ke. Tso cai rau koj siv cov khoom siv hauv xeev tau zoo dua thiab tiv thaiv kev ua haujlwm tsis zoo thiab / lossis lub neej. Koj tuaj yeem ua luas nrog ib qho kev hais kom ua "zpool trim" lossis ua kom muaj kev cuam tshuam ntawm kev xaiv pov tseg - lub pas dej tshiab "autotrim"
- Pas pib pib. Lub "zpool initialize" subcommand sau nws cov qauv rau tag nrho qhov chaw tsis tau faib. Qhov no tshem tawm thawj qhov kev nplua rau kev ua haujlwm uas yuav muaj nyob hauv qee cov khoom siv virtualized (xws li VMware VMDK).
- Project thiab quota accounting txhawb. Qhov no feature ntxiv qhov project thiab quota taug qab mus rau qhov chaw uas twb muaj lawm thiab quota nrhiav nta. Qhov project quotas ntxiv qhov loj me rau cov neeg siv ib txwm siv / pab pawg quotas. "zfs project" thiab "zfs projectspace" subcommands tau ntxiv los tswj cov haujlwm, teeb tsa cov kev txwv, thiab qhia txog kev siv.
- Channel cov kev pab cuam. "zpool program" subcommand tso cai rau koj siv LUA cov ntawv sau los ua kev tswj hwm. Cov ntawv sau tau khiav hauv sandbox nrog lub sijhawm thiab nco txwv.
- Pyzfs. Cov tsev qiv ntawv python tshiab los muab qhov chaw ruaj khov rau kev tswj hwm kev tswj hwm ntawm ZFS. Cov ntaub qhwv no muab ib daim ntawv qhia ib-rau-ib rau libzfs_core API ua haujlwm, tab sis cov npe kos npe thiab hom muaj ntau dua rau cov lus Python.
- Python3 Compatible. Cov khoom siv "arcstat", "arcsummary" thiab "dbufstat" tau hloov kho kom haum rau Python3
- Direct IO. Ntxiv kev txhawb nqa rau kev siv cov zis ncaj qha (O_DIRECT).
Cov tshuaj txhuam / resilver / npe / tau txais cov lus txib tseem tau nrawm dua, muaj peev xwm tso tawm cov metadata rau cov khoom siv sib cais (piv txwv li, qhov ua tau zoo me me SSD) tau ntxiv, ZIL kev ua tau zoo tau nce vim caching thiab optimization. , txhawb kev kho vajtse nrawm ntawm SHA256 checksum thiab AES encryption siv Intel QAT tau ntxiv (Quick Assist Technology).
Txhawb Linux kernels: 2.6.32 - 5.1 (SIMD acceleration tseem tsis tau txais kev txhawb nqa ntawm kernels 5.0 thiab siab dua)
Puv Daim ntawv teev cov kev hloov pauv
Lub default module parameter qhov tseem ceeb raug xaiv los muab kev pom zoo rau feem ntau ntawm cov haujlwm thiab kev teeb tsa. Rau ib daim ntawv teev tag nrho cov kev xaiv - txiv neej 5 zfs-module-parameters
