Vahetult hiljuti vabastasime uue stabiilse versiooni ZFSonLinux'ist, projektist, mis on n\u00fc\u00fcd keskne OpenZFS arendamisel. H\u00fcvasti, OpenSolaris, tere tulemast karm GPL-CDDL \u00fchtesobimatu Linuxi maailm.<\/p>\n

\"ZFSonLinux
\nAllpool on \u00fclevaade k\u00f5ige huvitavamatest asjadest (veelgi rohkem, 2200<\/u> komiteed!), ja magustoiduks \u2014 veidi intriige.
\n<\/a><\/noindex><\/p>\n

Uued funktsioonid<\/h3>\n

\nMuidugi on k\u00f5ige oodatum \u2014 kodune kr\u00fcpteerimine<\/b>. N\u00fc\u00fcd on v\u00f5imalik kr\u00fcpteerida ainult vajalikud andmestikud ZFS-i sisseehitatud kr\u00fcpteerimisega, ja (minu arvates \u2014 k\u00f5ige t\u00e4htsam) \u2014 saate kr\u00fcpteeritud andmeid saata l\u00e4bi zfs send<\/i> ja ILMA dekr\u00fcpteerimiseta kontrollida andmete terviklikkust sisseehitatud vahenditega; k\u00f5ik ZFS-i andmete terviklikkuse s\u00e4ilitamise v\u00f5imalused on teie k\u00e4sutuses!<\/p>\n

Edasi on olulisuse j\u00e4rgi mainimise all kauaoodatud TRIM<\/b>. Jah, ta j\u00f5udis tootmisse t\u00f5eliselt pika teekonna kaudu. Osaliselt seet\u00f5ttu, et CoW failis\u00fcsteemide jaoks ei ole SSD-de kulumise probleem nii kriitiline. Kuid n\u00fc\u00fcd oleme k\u00f5ik rahulikud \u2014 zpool trim <\/i>p\u00e4\u00e4stab meie \u00f5rnad m\u00e4lupulgad.<\/p>\n

N\u00fc\u00fcd on v\u00f5imalik kustutada<\/b> juhuslikult lisatud vdev massiivid basseinist (aga ainult, kui need on sparse v\u00f5i mirror). Kasulik detail.<\/p>\n

Edasi meie edetabelis \u2014 basseinide kontrollpunktid<\/b>. L\u00fchidalt \u2014 snapshotid kogu basseini seisundist, KUID annavad v\u00f5imaluse t\u00fchistada muudatusi mitte ainult andmetes, vaid ka basseinis lubatud omadustes ja struktuuri muudatustes. Veel \u00fcks v\u00f5imalus enda kaitsmiseks.<\/p>\n

Basseini initsialiseerimine <\/b> \u2014 alandamine aluseks oleva salvestusse nullide t\u00e4itmine. Kasulik t\u00f6\u00f6tamisel thin provisioned ketastega, et eraldada ruumi selgelt ja v\u00e4ltida hilisemaid ootamatuid j\u00f5udluse langusi.<\/p>\n

Projektiarvestus ja kvoot<\/b> \u2014 juba olemasolevas kvoodi mehhanismis on n\u00fc\u00fcd v\u00f5imalik kasutada projekti jagunemist.<\/p>\n

Kanali programmid<\/b> \u2014 v\u00f5imalus teostada haldus\u00fclesandeid atomaarseks kasutades Lua skripte. On piiranguid t\u00e4itmise ajale ja m\u00e4lule. Kui tegelete automatiseerimisega \u2014 siis see on teie jaoks.<\/p>\n

Otsene IO<\/b> \u2014 lihtsuse huvides on rakendatud Otsene IO, sees ei ole midagi muutunud (lihtsalt kutsed toimuvad maksimaalselt m\u00f6\u00f6da vahem\u00e4lu), kuid n\u00fc\u00fcd ei pea soovijad, kes tahavad selles re\u017eiimis t\u00f6\u00f6tada, muretsema.<\/p>\n

Projekt Pyzfs<\/b> lisatud p\u00f5hireposiiti ja v\u00f5etud ZFSonLinux'i projekti tiiva alla. N\u00fc\u00fcd on rohkem vahendeid, et hallata Pythoniga (ja ka mure modulaarsuse toetamise p\u00e4rast on v\u00e4iksem). Samuti on paljusid Python skripte kohandatud Python 3 jaoks.<\/p>\n

Ja n\u00fc\u00fcd maitsvad \u2014 j\u00f5udlus<\/h4>\n

\nN\u00fc\u00fcd, kui scrub ja resilver operatsioonid on k\u00e4imas, loetakse esmalt metaandmed ja seej\u00e4rel maksimaalselt j\u00e4rgnevate bittidena.<\/b> vormis \u2014 andmed. Nii et massiivi taastamine ja terviklikkuse kontrollimine toimuvad maksimaalsel kiirusel.<\/p>\n

Jaotuse klassid<\/b> \u2014 vdev massiividel on n\u00fc\u00fcd olemas kandjaklass, mis v\u00f5imaldab metaandmete\/deduplication table (DDT)\/blokkide hoidmise v\u00e4hem kui X Kbyte jaoks eraldi vdev massiivi paigutada rohkem tootlikest ketastest. Rohkem kiirus, kiirusel!<\/u> (ja asjakohaselt \u2014 see v\u00f5imalus osutub v\u00e4ga kasulikuks l\u00e4hitulevikus. DRAID<\/a><\/noindex>).<\/p>\n

Paljud halduskommandod t\u00f6\u00f6tavad n\u00fc\u00fcd kiiremini t\u00e4nu punkt-cache'ile metaandmetele (n\u00e4iteks, zfs list, zfs get<\/i>).<\/p>\n

Andmete jaotamise protsess on n\u00fc\u00fcd paralleelne<\/b>, n\u00fc\u00fcd iga vaba ruumi osa (metaslab) jaoks luuakse mitu allocatori. NVMe puhul ei pruugi k\u00f5ik olla v\u00f5imalik, kuid see paraneb.<\/p>\n

T\u00e4htsuse taastamine<\/b> massiivis v\u00f5imaldab mitte koormata massiivi samaaegse mitme ketta \u00fcmberpaigutamisega, vaid teostatakse seda j\u00e4rjestikku. Nii et see v\u00e4hendab m\u00f5ju j\u00f5udlusele ja \u00fcmberpaigutamise aega.<\/p>\n

Pohitellimisel koos suure hulga volumes<\/b> on kiirus nende registreerimisel s\u00fcsteemis suurenenud.<\/p>\n

Samuti QAT<\/b> k v\u00f5imaldab n\u00fc\u00fcd delegeerida kr\u00fcptimiskalkulatsiooni ja kontrollsummade kontrollimise.<\/p>\n

Pluss palju v\u00e4ikseid muutusi (\u00fcle 2000 kommi versioonis!).<\/a><\/noindex><\/p>\n

Ja l\u00f5ppu \u2014 intriigid<\/h3>\n

\nKuigi ZFSonLinux lisab kiiresti toetuse uutele Linuxi tuumadele (hetkel on toetatud versioonid 2.6.32 \u2014 5.1*), v\u00e4ljendavad tuuma hooldajad selget \u00fcksk\u00f5iksust kolmandate osapoolte moodulitele (\u201e\u2026me ei hooli \u00fcldse
\nv\u00e4listest tuumamoodulitest\u2026<\/a><\/noindex> \u2014 greg k-h\u201c). Nii et efektiivseks toimimiseks vajalikud tuuma k\u00f5ned versioonis 5.0 . Nendes tuumades, kus see patch on, on ZFS j\u00f5udlus oluliselt halvem. Aitavad, et seda funktsionaalsust on v\u00f5imalik rakendada mooduli poole pealt, mis t\u00f5en\u00e4oliselt ka tehakse. Ja seni v\u00f5ite v\u00f5tta eeskuju NixOSelt \u2014 nad <\/a><\/noindex>lihtsalt tagastasid patchi tuumas Samuti on projekt saanud k\u00e4itumisjuhendi, mis on tekitanud palju vaidlusi. Kuid me p\u00fcsisime \ud83d\ude42<\/a><\/noindex> \ud83d\ude42<\/p>\n

K\u00f5igile t\u00f6\u00f6kindlaid varukoopiaid ja stabiilseid versioone!<\/p>\n
