Kufike kimi ukuthi ngibhale mayelana Ama-Btrfs, uhlelo lwefayela okufanele ngokuzayo luthathe indawo yalo ext4, okumanje ebishesha kakhulu futhi isetshenziswa kakhulu, ngaphezu kokuchithwa kwayo cishe kucishe kube zero, ngaphandle kokuthi unediski enesikhala esigcwele esingaphezu kwama-95%.
Kepha yini i-Btrfs ehlela ukuyithuthukisa ngaleso sikhathi?
Ama-Btrfs uhlelo lwefayela olwakhiwe yi Oracle, ngokubamba iqhaza kwe- I-Red Hat, SUSE, Intel, phakathi kokunye. Mayelana nalokhu, kufanele kwaziwe ukuthi i-SUSE igcizelela ngokukhethekile ukuthi ilungele ukusetshenziswa endaweni yebhizinisi, futhi isivele inikezwa njengokuzenzakalelayo ekusatshalalisweni kwayo kwe-SUSE Enterprise.
Kungani kugcizelelwa kangaka ekusetshenzisweni kwayo? Lokhu kungenxa yokuthuthuka okuningi okulethwa ama-Btrfs, amaningi awo angowokuqala ngokuphelele futhi enza okusha okuningi endaweni yezinhlelo zamafayela. Ama-Btrfs uhlelo lwefayela kopisha-ngokubhala« ngifuna ukusimama, noma ngabe kukhona okungahambi kahle, kanye nokulula kokulungiswa kwesistimu nokuphathwa.
Izici eziyinhloko ze-Btrfs ezitholakalayo okwamanje yilezi:
- Isitoreji sefayela esisuselwa kusandiso
- 2 ^ 64 bytes == 16 EiB ubukhulu besayizi wefayela
- Isikhala sokupakisha sefayili esincane esisebenza kahle
- Izinkomba ezisebenza kahle zesikhala
- Ukwabiwa kwe-inode okunamandla
- Bhala izifinyezo, izifinyezo zokufunda kuphela
- Ama-Subvolume (hlukanisa izimpande zohlelo lwefayela langaphakathi)
- Amasheke okuhlola idatha nemethadatha (CRC32C)
- Ukucindezela (zlib ne-LZO)
- Ukusekelwa kwamathuluzi okushumeka amaningi
- Ukuhlukaniswa kwefayela, ukubukelwa kwesibuko, ukufakwa kwefayela + isibuko, ukuqopha ngokuqaliswa kokulingana okukodwa nokuphindwe kabili kwefayela
- Ukuqwashisa nge-SSD (i-Flash storage) (i-TRIM / Lahla ukubika amabhulokhi wamahhala wokuphinda uwasebenzise) nokwenza ngcono (ngokwesibonelo, ukugwema ukulungiselelwa kosesho okungadingekile, ukuthumela kubhala ngamaqembu, noma ngabe kuvela kumafayela angahlobene. imisebenzi emikhulu yokubhala nokusebenza kokubhala okusheshayo)
- Isipele sokukhuphuka esisebenza kahle
- Inqubo yokusula ngemuva ukuthola nokulungisa amaphutha kumafayili anamakhophi angafuneki
- Ukwehliswa kwesistimu yamafayela aku-inthanethi
- Ukuhlola uhlelo lokungaxhunyiwe ku-inthanethi
- Ukuguqula izinhlelo ezikhona ze-ext3 / 4 ezikhona
- Amadivayisi wembewu. Dala isistimu yefayela (efundwayo kuphela) esebenza njengesifanekiso sokutshala ezinye izinhlelo zefayela ze-Btrfs. Uhlelo lwangempela lwamafayela namadivayisi afakiwe njengendawo yokuqala yokufunda kuphela yohlelo lwamafayela olusha. Kusetshenziswa ikhophi-ebhaliwe, konke ukuguqulwa kugcinwa kumadivayisi ahlukile, okwangempela akukashintshiwe.
- Ukuxhaswa kwesabelo se-Subvolume -aware
- Ukuthumela / ukwamukela izinguquko ze-subvolume
- Ukusebenza Kwesistimu Yefayela Okukhulayo Okusebenzayo
- Iqoqwana, noma i-out-of-band, ukuphindaphindwa (okwenzeka ngemuva kokubhala, hhayi ngesikhathi)
Izici ezingeziwe ekuthuthukisweni noma kuphrojekthi yentuthuko:
- Akunasheke lokuxhuma kohlelo lwefayela olushesha kakhulu
- Izinga lezinto ukubukisa nokudweba
- Amanye ama-algorithm we-Checksum
- Ukuhlolwa kwesistimu yefayela eku-inthanethi
- Ezinye izindlela zokucindezela (ngokushesha, i-LZ4)
- Ukulandelela idatha eshisayo nokuthuthela kumadivayisi asheshayo (okwamanje acindezelwa njengesici esijwayelekile esitholakala nge-VFS)
- Ukudonswa kwe-in-band (kwenzeka ngesikhathi sokubhala)
Kufanele kucaciswe ukuthi ama-Btrfs isivele ibhekwe njengokuzinza nokuthi azikho izinguquko eziningi ezihleliwe ngokuzayo, ngaphandle kwalapho kunezizathu ezinhle kakhulu zokwenza lokho. Kodwa-ke, bazama ukuthuthukisa ijubane lama-Btrfs nge-Linux kernel ngayinye entsha, ngakho-ke kunconywa ukuba nayo njalo i-kernel efakiwe yakamuva nenguqulo yakamuva yokusatshalaliswa kwakho kwe-GNU / Linux.
Futhi, kunconyelwa ukushayela okukhulu ikakhulukazi, okuyilapho i-btrfs ivuselela kakhulu futhi izinzuzo zayo zingazwakala. Ngaphezu kwalokho, inokusekelwa kwe- ubuchwepheshe bamuvaNgakho-ke uma unama-SSD ngicabanga ukuthi uzobona ukuthuthuka okungaphezu kwe-ext4 njengoba i-ext4 isasebenzisa ubuchwepheshe obudala.
Okuhlangenwe nakho kwami
I-distro engiyithandayo kakhulu Vula i-OpenSUSE futhi yiyona engiyisebenzisa ku-netbook yami kusukela ngo-2011, ngakho-ke ngifomathe ukwahlukanisa ngama-btrfs ukuyivivinya, futhi iqiniso ukuthi lisebenze kancane kwi-netbook yami kune-ext4. Kuthathe isikhathi eside ukuqala ikhompyutha futhi ngazizwa nginamathele kakhulu, yize ngicabanga ukuthi ikopisha amafayela ngokushesha. Bangacabanga ukuthi ngichemile, kepha ngithathe izikhathi zokuphendula ukuze ngiqiniseke futhi bebehamba kancane futhi uhlelo luzwakale lubambeke kakhulu.
Iziphetho zami
Ama-Btrfs asevele ethathwa njengezinzile, ayicacisa ekhasini lawo elisemthethweni, ngakho:
- Uma une-PC endala, namathela ku-ext4
- Uma unokuthile okusha nge-SSD, sebenzisa ama-btrfs.
- Khumbula ukuthi bahlela ukwenza ngcono ukuhlanganiswa kwabo ne-Linux kernel ngayinye entsha, ngakho-ke ngokuzayo kungaba umqondo omuhle ukuyizama, ngakho-ke noma ngabe bane-Hardware yakudala manje, ijubane labo lingeqa lelo le-ext4 ngokuzayo, kepha kulokhu okwamanje, okungenani, akunconyiwe.
Kungadingeka ukwenza izivivinyo kwi-ultrabook ene-SSD, ukusho ngempela ukuthi ukusebenza kwayo kuphakeme yini, ngoba noma ngabe "kucatshangwa" ukuthi kuzoba namandla kakhulu kwi-Hardware nje "ngethiyori" kungabe kudonsa isifiso sethu ukutholakala. Ngokwabo, abantu basePhoronix babenze izivivinyo: http://www.phoronix.com/scan.php?page=article&item=btrfs_linux31_ssd&num=1
Iqiniso ukuthi liyindlela enhle kune-EXT4, okuthi, yize iyindlela engcono kakhulu kune-NTFS (kimi, edume kakhulu), ibijwayele ukungishiya nginomuzwa wokuthi iswele okuncane ukuze isebenze kangcono .
Noma kunjalo, ngiyethemba ukuthi kunguqulo elandelayo ye-Debian izotholakala.
I-PS: Ngisebenzisa i-Lynx ngoba ngixazulula inkinga nge-Intel video driver engiyifakile kudeskithophu yami ne-Debian.
I-Xubuntu 14.04 kuma-Btrfs: kweminye imisebenzi ihamba kancane kune-ext4 - ne-ext4 _is slow_, yize ingekho kakhulu njengobhatata we-NTFS.
Ngaphezu kwalokho, i-Btrfs akuyona uhlelo lwefayela njengoba sijwayele, yindawo yonke uqobo lwayo, uma ungeke ufunde i-wiki ngokuningiliziwe, ungayifaki, kuzoba ngamakhanda (ngokwesibonelo amathuluzi afana ne- df [dfc] noma i- du [ cdu] azisebenzi kahle kuma-Btrf futhi kufanele usebenzise amathuluzi akho).
Endabeni yami ekugcineni ngakhetha ama-Btrfs kwazise ukufakwa kweWincrap kunzima ukusebenzisa i-LVM, ungakwazi kepha kufanele wenze umlingo ngesandla bengifuna ukuthi iphengwini lami ligijime ngokushesha okukhulu.
Uma ungenayo i-Winbosta efakiwe, i-LVM + ext4 iyinhlanganisela enhle kakhulu: ukuguquguquka nokuvikeleka kokusebenzisa i-LVM enesistimu yefayela eqhubeka ithuthuka - futhi i-gilada yayilwa kanzima ngaleso sikhathi ...
Mina, inkinga akuyona i-NTFS ngqo, kepha i-interface yeWindows Vista uqobo.
Siyabonga ngokuphawula. Angikaze ngisebenzise i-LVM futhi ngicabanga ukuthi ngeke, kepha kuhle ukwazi lezi zinto. Ngendlela, yikuphi ukuthuthuka okusebenzisa i-LVM?
I-Btrfs uhlelo lwefayela. I-LVM uhlelo lokuhlukanisa. Kunombhalo ophelele ku-Wikipedia.
Okufanayo kimi, ngibonile ama-btrfs ahamba kancane kakhulu, ngincamela i-ext4.
Kuliqiniso, kwenzeke kimi, bengifuna ukuzama futhi ngakuqaphela kancane kakhulu.
i-ext4 ayikanginiki izinkinga kuze kube manje
Ngine-boot ebili ngakho-ke ezinye izingxenye ku-ntfs
futhi iqiniso ukuthi angikuboni ukwehluka nge-ntfs
okwamanje angizukuzama izinhlelo zefayela
Sisesimweni esifanayo uma kukhulunywa ngokuhlolwa kwesistimu yefayela.
Njengamanje ngisebenzisa uDebian Lenny ngama-reiserfs 3.6 system system kwi-PC yami yedeskithophu, njengoba isivele iphelelwe yisikhathi ngiqale ukuhlola (kwenye idiski) noDebian Wheezy. Njengoba ama-reiserfs engasatholakali ukuthi asetshenziswe ekufakweni (yize kungenzeka ukufaka uhlelo engxenyeni efomethwe ngaphambilini ngama-reiserfs), ngenze izivivinyo ngama-btrfs, ext4 nama-xfs, ngokungezelela kuma-reiserfs anendlela eshiwo ngenhla. Ukusuka ezivivinyweni ezenziwe into efanelekile engiyibonile ukuthi womabili nge-ext4, ama-reiserfs nama-xfs ukusebenza bekucishe kufane, mhlawumbe ngombono wokushesha kancane lapho usebenzisa ama-xfs, kepha bekuhamba kancane kakhulu lapho usebenzisa ama-btrfs, empeleni ukufakwa kuphela kuthathe cishe izikhathi eziphindwe kathathu kulolu hlelo lwefayela. Futhi, njengoba bekulindelwe nge-ext4, cishe i-5% yesikhala esisebenzisekayo siyalahleka lapho kuhlukaniswa, ngakho-ke angikaze ngicabange noma iyiphi i-ext * inketho enhle. Njengoba ngafaka i-distro yami yokuqala (Suse Linux 6.4) kwi-PC ene-20 Gb disk engiyisebenzisile ama-reiserfs (emuva ngaleso sikhathi kwakungokokuhlola). Kumele sisho ukungabi bikho kwama-reiserfs, ngaphandle kokuthi ayisekho intuthuko nokusekelwa okusebenzayo, yisikhathi eside esithathayo ukukhuphuka, ngokubonakala ngokwengeziwe lapho ukwahlukanisa kukhulu. Ngokuphathelene nama-xfs, ububi engibutholile ukuthi abungeke bukhuliswe ...
Ngifuna imininingwane ku-Intanethi mayelana nezinhlelo zamafayela ezitholakalayo ukufaka ama-reiserfs ngifunde ezinye izindatshana lapho bezikhombe khona kuma-xfs ngoba inokwakheka okuhle nokuthuthuka okusebenzayo futhi ivuselelwa ukusizakala ngama-processor anamuhla amaningi, ngokungeziwe leyo Red Hat isethe ukubheka kwayo kulolu hlelo lwamafayela.
Noma kunjalo, okomzuzwana ama-xfs ngiwuthatha njengendlela engcono kunazo zonke, okungenani kwideskithophu, ukuphinda ufake ama-reiserfs (ngenhla kwe-ext * nama-btrfs).
Ulwazi olukhulu, kubonakala sengathi ama-xfs ayindlela enhle kakhulu, yize ngijwayele ukukhulisa usayizi wediski kancane, ngakho-ke angazi ukuthi ngizoyisebenzisa yini, kodwa nakanjani ngizozama.
Ulwazi alulukhulu kangako, hlola impendulo yami.
Ukuhlolwa kwakho kokusebenza kwe-Btrfs kuhlanekezelwe, ngicabanga ukuthi ngenxa yokushoda kolwazi.
I-Wheezy isebenzisa i-kernel 3.2 okuyizindinganiso zanamuhla i-quasi Paleolithic.
Njengabo bonke ubuchwepheshe obuningi ku-Linux, inqwaba ye-Btrfs ikwi-kernel efanayo hhayi kuzinhlelo zokusebenza zomsebenzisi, ngakho-ke kube nokufakwa okungenakubalwa kwezici nama-bugfixes kusuka ku-kernel esebenzisa 'endala' ku-kernel esiyisebenzisayo namuhla kwamanye ama-distros anamuhla (3.12,3.13 no-3.14).
Ku-Xubuntu 14.04 (izinhlamvu 3.13 no-3.14-pf) ne-ChakraOS (i-kernel 3.12.6) i-Btrfs isebenza ngokungenaphutha uma kungenjalo kune-ext4. Inhlawulo okuyiyo enayo ngokuya ngejubane lokufunda nokubhala isekusebenzeni kwedathabheyisi enkulu - okubhalwe isikhangiso nauseam.
Kuyiqiniso ukuthi ngezinguqulo zakamuva kakhulu ze-linux abashayeli be-btrfs kumele ukuthi bathole okungeziwe okungenakubalwa kwezici nama-bugfixes, kepha lokho kuzoba yiqiniso nakuma-xfs.
Yize noma ngintula ulwazi lobuchwepheshe nolunzulu mayelana nezinhlelo zamafayela, ama-linux driver, nabanye ... Ngaphandle kweqiniso lokuthi eminyakeni edlule ngiyekile ukuzama nokuzama ngazo zonke izinhlelo ze-distro nezinhlelo ezintsha engizitholile (izikhathi ezimnandi!) yingakho ngisasebenzisa uDebian Lenny! hehe! Kungakho angikenzi ukuqaqa kusuka ku-distro kuze kube yilapho ucwaningo lwami nokuhlolwa kwami kusistimu yamafayela engizokusebenzisa ukumiselela ama-reiserfs kuphelile; ukuthi njengamanje umfakisicelo wokuqala nguma-xfs. Ngiyakholelwa futhi ukuthi nginemibandela eyanele nekhono lokukhetha engicabanga ukuthi kungaba okungcono kakhulu okufanela izidingo zami, okusondele kakhulu kunoma yimuphi umsebenzisi ojwayelekile we-PC yasekhaya ...
Ngishiya isixhumanisi esihlokweni esithakazelisayo esibizwa ngokuthi: I-Red Hat icabanga ukuthi i-XFS uhlelo lwefayela olungcono kune-Ext4. Engiqokomisa kuwo umusho onikeza umbono wokuthi kungani ama-btrfs angahle ahambe kancane kune-xfs: ... Ukwenza amakhophi angafuneki emethadatha, ngokwesibonelo, kunikeza ukuphepha, kepha ukubhala idatha efanayo kabili kudiski kuzohlala kuhamba kancane kunalokho wenzeni…
Xhumanisa ne-athikili: http://diegocg.blogspot.com.ar/2013/06/red-hat-xfs-es-mejor-sistema-de.html
"Kuyiqiniso ukuthi ngezinguqulo zakamuva ze-linux abashayeli be-btrfs kumele bathole izengezo ezingenakubalwa zezici nama-bugfixes, kodwa lokho kungaba yiqiniso nakuma-xfs."
I-syllogism engalungile: "Kuyiqiniso ukuthi inja yami yaseDalmatia inemilenze emi-4 nomsila o-1, kufanele kube yiqiniso-ke ukuthi zonke izinja ezinemilenze emine nomsila owodwa zimhlophe futhi zinamabala."
Ingabe uyakulandela ukwakhiwa kweXFS? Hhayi mina, kepha ngingalokotha ngithi akusondele ngisho nejubane lokuthuthuka le-Btrfs. Eqinisweni ... inentuthuko yamanje, noma ama-bugfixes nje? Iminyaka ingahamba, ingunaphakade uma ufuna futhi ukusebenza ngeke kuthuthuke uma kungekho noyedwa ngemuva kwendololwane 😀
Ngibuqonda kahle ubuhlungu bakho bokushiya iReiserFS, olunye lwezinhlelo zamafayela ezihamba phambili ngaso sonke isikhathi, okuyihlazo ukuthi abaluvumeli ukuthi luqhubeke nokukhula ...
Ngokuphathelene nesidingo sakho sokubheka uhlelo olusha lwefayela, ngincoma i-LVM + ext4 combo, i-Btrfs ihluke kakhulu, kufanele ufunde okuningi ukuze uyisebenzise kahle futhi uyixhaphaze ngokusemandleni ayo, ngokuqinisekile akuyona i- "install and khohlwa "ubuchwepheshe njengoba uManuel echaza kusixhumanisi sakhe, okubandakanya umsebenzi owengeziwe okumele ugcinwe.
Uma ungenayo i-Wincrap efakiwe, i-LVM + ext4 iyakhazimula. Eqinisweni i-Btrfs ihloselwe kancane ukufaka esikhundleni sohlelo lwefayela le-LVM + X.
Ngokuqondene noDebian, ungahle uthande ukuzama iTanglu (eshiwo lapha ku-DL), iSemplice (eyenziwe yaqina iSid) noma amanye ama-distros amasha azama ukuthuthukisa iDebian ehlanzekile, eyisisekelo ekusetshenzisweni nakubuchwepheshe banamuhla.
Ukubingelela
Kimi kwangikholisa lapho ngizama iGnome Imibhalo. Nge-ext4, ukufuna imibhalo kwathatha amakhulu eminyaka. Nge-btrfs kwakuwukusebenza okusheshayo.
Ngiyisebenzise ne-fedora 16 futhi angibonanga zinguquko. Emuva lapho kwakuthathwa njengokungazinzile ngakho-ke ngangigcina i-ext4 yami yempilo yonke
I-BTRFS uhlelo oluhle kakhulu lwefayela, phakathi kwezinzuzo engiziqaphelile ijubane elikhulu kumakhompyutha ami (ukusebenzisa ukwahlukanisa / ngaphansi kwe-BTRFS) kumaseva, ukubekezelelana okukhulu emaphutheni adala ukonakala kwedatha (Ngaphansi kwe-Ext4 uma ucisha iseva leyo isebenzisa i-daemon ye-MongoDB i-database idinga ukuthi uyiqalise kabusha ngesandla ngokususa ifayela «/var/lib/mongodb/mongod.lock» bese uqala kabusha i-mongod daemon, ngaphansi kwe-BTRFS lokhu akwenzeki ngenxa yesakhiwo sayo se-CoW nezinye izinto "Goodies" "). Ngaphezu kokukwazi "ukuvuselela" ama-hard drive alimele (Ngokusobala phambilini babene-Windows NTFS futhi bagcina sebebi kakhulu kangangokuba abakwamukeli ukufakwa kwe-Linux nge-Ext4 nakanjani).
INKINGA ukuthi i-BTRFS ayilona uhlelo lwamafayela olusebenzela "ngaphandle kwebhokisi" lomsebenzisi njenge-ExtX, engadingi ukugcinwa okuqhubekayo noma ukwenziwa ngcono. Bengilokhu ngisebenzisa i-BTRFS ekukhiqizweni kusukela ku-Fedora 15 (ngiku-Fedora 20 njengamanje), futhi ngokuhamba kwesikhathi ngiqaphele izinto eziningi ezidingekayo ukuze zisebenze kahle, kufaka phakathi nezinqubo zokulungisa engizichazayo Lesi sihloko:
http://xenodesystems.blogspot.com/2014/05/btrfs-maintenance-and-other-tips.html
(Ngalokho, phakathi kwezinye izinto eziningi, ukwahlukana okujwayelekile okubandakanya lolu hlelo kugwenyiwe)
futhi ngithole nokuthi ukuba uhlelo lwefayela le-CoW yonke into "indawo, indawo, indawo." Uyabona, i-BTRFS yinhle ku / ukwahlukanisa ngohlobo lwayo kanye nephrofayili yokufinyelela kufayela, kepha uma uyifaka engxenyeni / ekhaya bese ulindela ukusebenzisa isibonelo into ebuyela emuva ibhalela i-hard drive (njenge umshini osebenzayo one- "hard disk" eku-btrfs yasekhaya / yasekhaya) uhlelo lumane lube yiqhwa ngoba i-CoW ayenzelwanga lolo hlobo lokusebenza (yize lusebenza kuyo) ...
Ekupheleni kosuku ngicabanga ukuthi kungenxa yalezi zinto ukuthi namanje asikuboni "njengokuzenzakalelayo okuzenzakalelayo" kwama-distros amaningi okwamanje, ngoba lezi zinto ziyizindawo ezisebenza ngaphandle kokungabaza.
Ulwazi olukhulu, yebo ngingeze lezo zinzuzo kokuthunyelwe, kepha ngingumsebenzisi wasekhaya (uma sikhuluma), lezo zinketho azibalulekile kimi futhi anginaso isiqiniseko sokuthi zisebenza kanjani nhlobo, ngakho ngagcina engisebenzele kahle kakhulu. Noma, futhi ngizohlola ama-xfs ngalokho abakushilo ngenhla.
xfs
Nge-SSD ngizobheja kuma-f2fs
Ngizwile izinkomba ezinhle kuma-btrfs, futhi inkinga ukushintsha (uma bengifuna), kufanele ifomathe konke, futhi njengoba nginolwazi oluningi kakhulu, ngizoba nezinkinga zokukusekela ._.
Futhi kuhle ukuthi besivele sizinzile, noma angazi noma kuwo wonke ama-distros (lapha eGentoo icala alikakhulunywa ngalo). Okwamanje, nginamathela ku-ext4 ngezinkinga zenkambiso nokuzinza.
Futhi anginawo amadrama ngokuthola amafayela, futhi nginobunzima bokukhomba ukusheshisa ukusesha, ngenxa yesikhala sediski esidingekayo: /
Ngingazama ama-btrf uma kukhulu ngokwengeziwe futhi ngithole ukuthi ungazenzela kanjani isikhashana (futhi nalapho une-hard drive enkulu :)
Sawubona, kuthathwa njengokuzinza konjiniyela bayo ngaphezu kwanoma yini enye, kwamanye ama-distros, ngaphandle kwe-SUSE noma i-Fedora, futhi akukhulunywa ngayo, yize i-SUSE isivele isiyamukele njengoba ngishilo ngenhla.
Mmm manje ngiyaqonda. Ngizolinda ngokuhamba kwesikhathi. Ngiyabonga 😀
Cha, awudingi ukufometha konke. Izingxenye ze-extX zihanjiswe ngokusobala ziye kuma-Btrf ngenzuzo yokubuyisa ushintsho (okungukuthi, ukubuyela kusistimu yakho yefayela yakudala) uma ufisa.
Kuhle ukukwazi. Ngizolinda ama-Btrfs abe nokuxhaswa okuningi njenge-ext4 futhi abe mkhulu njenge-ext4 manje. Futhi ngiyabonga, kungishiya ngithule uma kukhulunywa ngokufuna ukuphikisana naleso sistimu yefayela 😀
Ngine-BTRFS kuma-SSD ami womabili eKaOS nase-Antergos, ngoba manje angikaze ngibone lutho olungajwayelekile, okusho ukuthi, ngine-fstab conditioning.
Ngibashiya uma kungenzeka kusize umuntu.
Okuzenzakalelayo kwe-UUID = xxxxacaminumeroxxxxxx / btrfs, rw, noatime, compress = lzo, ssd, space_cache, inode_cache 0 0
Ngine-btrfs kuphela ku- / izimpande, futhi angisebenzisi ngokwahlukana / kwasekhaya noma ngishintshe
Bheka isixhumanisi esithunyelwe nguManuel ukuze ungeze ukwenziwa okuhle kwi-SSD yakho.
I-XFS iyaqhubeka nentuthuko futhi ifaka phakathi ukuthuthuka kwezinhlamvu ezintsha, setha inketho yokubambezeleka.
Ngabe usebenzise ukuhumusha komshini kuzinzuzo? ngoba ibhalwe isimanga kakhulu.
Kuyini lokho kuhunyushwa komshini? Inketho ye-wordpress?
Ngisabambelele ku-ext3
Kuze kube ngidlula i-ext4 ngejubane (ngokuya ngezivivinyo engizifundile, kukude kakhulu okwamanje) angisitholi isizathu sokushintsha.
Lowo akuyona inhloso ye-Btrfs
kodwa ingabe kumahhala?
Futhi ... uma kuyingxenye yenhlamvu ...
Ngishiye nge-ext4 esebenza kahle kakhulu yize nginomshini omusha kakhulu one-ssd. 🙂
Ngisebenzisa i-XFS kusukela Ubuntu 10.04 futhi kimi kungcono kakhulu okusebenzayo!
Ama-Btrfs asenendlela okufanele ayenze.
Okwamanje, i-XFS ingumngani wakho.
Kusetshenziswa ukuminyaniswa, nge-kernel 3.12.x, lonke uhlelo lwefayela luyonakaliswa ngemuva kokubhalwa kwediski esindayo. Ixwayisiwe…
Ngicabanga okuningi ngokuthi yiluphi uhlelo lwefayela okufanele ngilusebenzise. Angazi noma ngisebenzise i-BTRFS, i-ZFS noma i-XFS. Manje ngemuva kokufunda i-athikili isixhumanisi sayo, ngezansi kwala magama anamathiselwe, ngicabanga ukuthi ngizoqala ukusebenzisa ama-btrfs.
http://libuntu.com/marc-merlin-de-google-habla-sobre-las-ventajas-de-btrfs-y-las-desventajas-de-zfs/
ZFS ku-GNU / Linux? Ngikufisela inhlanhla, ngivele ngilokhu ngicabanga.
Akudingeki ucabange kakhulu 😉

Ngisanda kuthenga iprosesa ye-Pavillion laptop ye-AMD A8, i-8 GB yenqama enamafasitela efakwe amawindi 8.1, ngathenga ne-disk engu-160 GB SSD ngase ngiqala ukufaka Ubuntu 14.04 LTS kwi-SSD ngokuxhuma kwangaphandle kwe-usb (ngisebenzisa i-SSD disk ngaphandle ikhompyutha ukuze ungathinti noma yini ngaphakathi kwe-laptop), ekufakweni kwe-Ubuntu ngikhethe ukufakwa okuzenzakalelayo, konke kwahamba kahle, ngaphandle kokwenza okunye ukusebenza ngemuva kokufakwa, lapho ngivula ikhompyutha ngokuzenzakalela imenyu ivela ukuthi Inikeza inketho yokuqalisa nge-Ubuntu noma nge-Windows, bengingakaze ngizame uBuntu kukhompyutha yesimanje enesizotha futhi ene-disk ye-SSD, ayisebenzi, iyandiza, kepha bengilangazelela ukubona ukuthi ukusebenza kukaBuntu kuzohlukaniswa ini Ama-Btrfs, anginawo amakhono ajule kakhulu wekhompyutha kepha bengisebenzisa Ubuntu isikhathi esithile futhi ngithanda ukucwilisa futhi ngizame izinketho ezahlukanisayo zokuqhathanisa imiphumela, Lapho ngibheka kakhulu kuwebhu angiboni okokufundisa okuphelele okuvumela ukwenza ukwahlukaniswa okuthuthukile ku-linux usebenzisa i-SSD disk, uma uneseluleko kulokhu, ngithokozela ukunakwa kwakho kusengaphambili ... haaa ... ngu indlela, siyakuhalalisela ... Isihloko esihle.
Sanibonani nonke, bengifuna isistimu yefayela efanelekile ukuphatha amafayela amakhulu, ikakhulukazi amafayela evidiyo.Ngabe kufanele ngilungiselele ukwahlukanisa okukhethekile ngefomethi ye-XFS? Njengamanje ngisebenzisa i-ext4, kepha-ke nginamafayela azo zonke izinhlobo ekhaya / ekhaya.
Kulesi sahlukaniso ngokuyisisekelo kuzoba ukufunda amafayela kuphela.
Ngisebenzisa i-Lenovo ideapad s400touch laptop enezingxenye ze-ubuntu 14.01 no-4, / boot, swap, / and / home.
Ukubingelela nokubonga ngokungifunda.
Nilale kahle nonke. Nginomshini wokukhiqiza onediski ye-SSD engifaka kuyo i-OpenSUSE ngama-btrfs. Izici zayo ziyajabula futhi empeleni kuyashesha kakhulu ekuvinjweni kweseva nezinqubo zokuqalisa. Kulesi sistimu yamafayela kubekwe imininingwane egciniwe yokukhiqiza yebhizinisi lami, kepha bekufanele ngiphinde ngifake ikhompyutha yami futhi, ngoba ibingasekeli ukwehluleka kwamandla futhi lolu bekungukuphela kohlelo lwefayela olonakele. Angikwazanga ukubuyisa isistimu yefayela ukuyenza ikhuphuke. Nge-btrfs Buyisela Umbuso ngikwazile ukuthola i-database, kepha noma kunjalo, ibivele yonakele futhi bekungenakwenzeka ukuyithola ngezinsizakusebenza zezinyoni zomlilo. Iqiniso ukuthi kungidalele inkinga enkulu ngoba amarekhodi okuthengisa alahlekile usuku lonke lwesigamu (lawo amarekhodi amaningi), izinkinga zempahla, njll. Angikukhuthazi ukuthi kukhiqizwe ekugcineni.
Sanibonani nonke, ngisebenzisa iXubuntu 14.04.01 LTS selokhu yaphuma futhi iyangikhuthaza ukuthi ngishintshe i-ext4. Kimi / ngisebenzisa ama-btrf kanye ne / ekhaya ngisebenzisa ama-xfs futhi iqiniso ... limane nje lihle kakhulu, noma ngama-xfs ukukopishwa kwamafayela amakhulu kwenziwa ngokushesha kunangesikhathi ngisebenzisa i-ext4. Angiqondi lutho mayelana nezinhlelo zamafayela, kepha iqiniso ukuthi, ngikhuthazekile ukuzama futhi ngijabule kakhulu ngomphumela, angazi ukuthi kuzokwenzekani kamuva. 🙂
Hola
Ngivele ngangena enkingeni yokuthi ngine-oracle linux (redhat) server ene-LVM. Bengine-7gig FS btrfs lapho ngibeke khona yonke into / bese ngifaka enye i-2G yokushintshana. Iqiniso ukuthi bekuyi-petado kepha bekukhona i-disc eningi engasetshenziswanga.
Ngithathe futhi ngehlise ukushintshaniswa futhi ngilayishe ivolumu enengqondo yokushintshaniswa. Ngemuva kwalokho ngidale ukwahlukanisa nge-fdisk nayo yonke enye indawo engasetshenziswanga engasetshenziswanga kanye nevolumu ebonakalayo yalokhu ngakungeza eqenjini levolumu. Futhi ekugcineni, ngikwandisile i-VL lapho uhlelo lwefayela le-btrfs lukhona (kufakwe KONKE into / /) futhi ngidale i-VL entsha yokushintshanisa eqamba kabusha okufanayo ukuze sigweme ukuthinta i- / etc / fstab (umthetho wokuzama okuncane).
Kuze kube manje akukho okungajwayelekile kulabo abaziyo ukusebenzisa i-LVM. Ngisebenzisa imiyalo yokubonisa ngibona ama-VL ami ama-2 (impande nokushintshana) futhi impande eyodwa ibivele inesikhala ebengisidinga. Kepha-ke lapho senza i-df -h siyaqhubeka nokubona amandla amadala we-FS (7gigas). Ngakho-ke ngahamba ngayokwenza usayizi2fs futhi kulapho (ngemuva komyalezo wephutha) ngathola ukuthi i-FS kwakungu-btrfs futhi kwakufanele ngiye ku-inthanethi ukuthola imininingwane. Ngibheke imiyalo yokwenza usayizi oshisayo (noma yini ekhulisa usayizi akudingeki ukuthi yehliswe).
#btrfs systemystem resize + 10G /
Lowo bekungumyalo osetshenzisiwe. Futhi ngingasho ukuthi kwavela kuphelele. Ngaleso sikhathi ngenza i-df -h futhi amandla amasha ayephuma. Konke lokhu bekusempandeni FS (/) futhi konke kushisa kusuka kuleyo seva efanayo. Ngaphandle kokuthi uqale noma iyiphi i-livecd noma yini.
Sengiphetha, konke kulungile. ama-btrfs ne-LVM bathatha umama dp.
Bye
Esinye sezihloko eziningi okuthiwa ezobuchwepheshe ezihlanekezela indawo yonke yezobuchwepheshe nokuthi ekugcineni zimane nje "zingamazwana nokubongwa komuntu siqu." Akukho datha enenhloso, futhi esikhundleni salokho kukhona «Ngicabanga» «Ngenze izivivinyo (idatha yazo engashicilelwe» ...
Ngakolunye uhlangothi, i-distro esetshenzisiwe kanye ne-kernel yayo ngaphezu kokuphelelwa yisikhathi, akubona ubufakazi obunokwethenjelwa bokuthile.
Futhi akakaze azihluphe ngokuhumusha ikhophi lokunamathisela mayelana nezici ze-BTRF kahle. Ngamafuphi, i- «athikili» ejwayelekile, enikela kakhulu, yenzelwa ukuwina ukuvakashelwa ...
Sanibonani nonke.
Okokuqala, okushiwo nguMnu. Mateos kuliqiniso, konke kusekelwe kokuhlangenwe nakho nokufundwa okuvela "ngaphandle lapho", kodwa kuyiqiniso ukuthi konke kuyasebenza, bambalwa abangaqonda imininingwane enjalo yobuchwepheshe.
Mayelana ne-fs, ngisebenzisa i-openSUSE kusukela ekuqaleni, ngivivinye ukuthi mangaki ama-distro awele indlela yami, ku-netbook engenamandla kakhulu, i-4GB ram ne-cpu celeron 1.6 Ghz x2. Kusukela enguqulweni 13.2, ukwahlukanisa ngama-btrfs ku / kanye nama-xfs ku / home kuzenzakalelayo. USUSE ukwenzile futhi ngesizathu kunjalo. Iqiniso ukuthi lisebenza kahle, ayikho enye i-distro esebenza njenge-OpenSUSE, ijubane lokusesha kudeskithophu liyashesha, liyakopishwa, lisikiwe, linamathiselwe yonke into lishesha, ngaphezu kwama-debian nama-derivatives, (iqiniso ukuthi namanje angiqondi ukuthi kanjani Abasebenzisi be-Linux basebenzisa Ubuntu).
Ngafaka ubuntu nge-ext4 bese ama-btrfs futhi eyokugcina ibingcono, angazi ukuthi kungani, kepha bekuyiyo.
Ukuqhubeka nama-btrfs, i-SUSE kanye nenkampani ikusebenzisa ngokuzenzakalela ngoba ifaka izifinyezo zokululama, ngaphandle kokuthi ube yingcweti yokululama uma kwenzeka inhlekelele.
Iqiniso, akukho okungcono kunokuvulekaSUSE, futhi hhayi ukuhlala ku-13.1 nje ngaso sonke isikhathi, ushintsho ku-13.2 luyamangalisa. Ngeke ngincome noma ngisebenzise noma yini ngaphandle kwe-chameleon distro.
Sanibonani nonke futhi… NIZIJABULISE KAKHULU !!
Ngisebenzise uhlelo lwefayela le-btrfs nge-microsd futhi bekunzima ukulifometha ngokuhamba kwesikhathi, ngemuva kokusebenzisa amasistimu amaningi wokufomatha. Okuhlangenwe nakho okubi, yize uhlelo lubukeka luthembisa, ikakhulukazi kuma disks e-ssd, inqobo nje uma izinkinga ezinjengalezi ezenzeke kimi zinganqotshwa.
