Ho nkile bahlahisi ba ZFS ho Linux (e khutsufalitsoeng ZoL) hoo e ka bang lilemo tse peli le tokollo ea 5 RC ho lokolla tokollo ea bohlokoa haholo - ZFS-0.8.0.
Menyetla e mecha:
- "Native" encryption bakeng sa litsamaiso tsa lifaele le likarolo. Algorithm ea kamehla ke aes-256-ccm. Linotlolo tsa dataset li laoloa ka ho sebelisa taelo ea "zfs load-key" le li-subcommands tse amanang le tsona.
- Encryption ka zfs send/receive. E u lumella ho boloka li-backups lits'ebeletso tse sa tšepahaleng ntle le monyetla oa ho sekisetsa.
- Ho tlosa sesebelisoa ho tloha letamong ka taelo ea "zpool tlosa". Lintlha tsohle li kopitsoa ka morao ho lisebelisoa tse setseng tsa boemo bo holimo, 'me matla a letamo a fokotsehile ka tsela e nepahetseng.
- taelo e nyenyane ea "zpool checkpoint". e u lumella ho boloka boemo bohle ba letamo 'me, haeba u lakatsa, u khutlele sebakeng sena se nepahetseng. Sena se ka nkoa e le setšoantšo se atolositsoeng sa letamo. Sena se na le thuso ha o etsa liketso tse rarahaneng tsa tsamaiso tseo ka tsela e 'ngoe li ke keng tsa fetoloa (joalo ka ho nolofalletsa karolo e ncha, ho senya sete ea data, joalo-joalo)
- TRIM bakeng sa lisebelisoa tsa letamo. E u lumella ho sebelisa li-drive tsa boemo bo tiileng hantle le ho thibela ho senyeha ha ts'ebetso ea tsona le/kapa bophelo bohle ba tsona. O ka etsa trim ka taelo e arohaneng ea "zpool trim" kapa oa lumella analogue ea khetho ea ho lahla - thepa e ncha ea letamo "autotrim"
- Ho qala ka letamo. "Zpool initialize" subcommand e ngola mohlala oa eona sebakeng sohle se sa abuoang. Sena se felisa kotlo ea pele ea ts'ebetso ea phihlello e ka bang teng lihlahisoang tse ling tsa polokelo tse fumanehang (joalo ka VMware VMDK).
- Ts'ehetso ea li-accounting tsa projeke le quota. Karolo ena e eketsa tlhahlobo ea projeke le quota sebakeng se seng se ntse se le teng le likarolo tsa ho latedisa quota. Likarolo tsa projeke li eketsa karolo e 'ngoe ho tse tloaelehileng tsa basebelisi/sehlopha. "zfs project" le "zfs projectspace" litaelo tse nyane li kentsoe ho laola merero, ho beha meeli ea palo, le ho tlaleha ts'ebeliso.
- Mananeo a kanale. "Zpool program" subcommand e u lumella ho sebelisa mangolo a LUA ho etsa liketso tsa tsamaiso. Lingoliloeng li tsamaisoa ka har'a sandbox e nang le meeli ea nako le mohopolo.
- Pyzfs. Laeborari e ncha ea python ho fana ka sebopeho se tsitsitseng bakeng sa tsamaiso ea lenaneo la ZFS. Sephutheloana sena se fana ka 'mapa oa motho a le mong bakeng sa mesebetsi ea libzfs_core API, empa li-signature le mefuta li tloaelehile ho puo ea Python.
- Python3 e lumellana. Lisebelisoa tsa "arcstat", "arcsummary" le "dbufstat" li ntlafalitsoe hore li tsamaisane le Python3.
- Ka ho toba IO. Tšehetso e ekelitsoeng bakeng sa ho sebelisa tlhahiso e tobileng (O_DIRECT).
The scrub/resilver/list/get subcommands le tsona li potlakisitsoe, bokhoni ba ho hlahisa metadata ho sesebelisoa se arohaneng (mohlala, SSD e sebetsang hantle haholo) e kentsoe, ts'ebetso ea ZIL e ekelitsoe ka lebaka la caching le optimization. , tšehetso bakeng sa ho potlakisa hardware ea SHA256 checksum le AES encryption ho sebelisa Intel QAT e kentsoe (Quick Assist Technology).
Lithako tsa Linux tse tšehelitsoeng: 2.6.32 - 5.1 (Ho potlakisa SIMD ha ho so tšehetsoe ho li-kernels 5.0 le holimo)
E felletse Lethathamo la liphetoho
Litekanyetso tsa paramethara tsa module li khethiloe ho fana ka mojaro o nepahetseng bakeng sa meroalo e mengata ea mesebetsi le litlhophiso. Bakeng sa lenane le felletseng la likhetho - monna 5 zfs-module-parameters
