I-Raspberry Pi Yenza Ukuqina Kakhudlwana File Umhlahlandlela Womsebenzisi Wesistimu

Amadivayisi we-Raspberry Pi Ltd avame ukusetshenziswa njengendawo yokugcina idatha kanye namadivayisi okuqapha, ngokuvamile ezindaweni lapho ukwehla kwamandla kungazelelwe kungenzeka. Njenganoma iyiphi idivayisi yekhompyutha, ukuphela kwamandla kungabangela ukonakala kwesitoreji. Leli phepha elimhlophe linikeza ezinye izinketho zendlela yokuvimbela ukonakala kwedatha ngaphansi kwalezi zimo nezinye ngokukhetha okufanele file amasistimu nokusetha ukuqinisekisa ubuqotho bedatha. Leli phepha elimhlophe lithatha ukuthi i-Raspberry Pi isebenzisa isistimu yokusebenza ye-Raspberry Pi (Linux) (OS), futhi isesikhathini samanje ne-firmware yakamuva nama-kernels.

Kuyini ukonakala kwedatha futhi kungani kwenzeka?
Inkohlakalo yedatha isho izinguquko ezingahlosiwe kudatha yekhompuyutha ezenzeka ngesikhathi sokubhala, ukufunda, ukugcinwa, ukudluliswa, noma ukucutshungulwa. Kulo mbhalo sikhuluma kuphela ngokulondoloza, esikhundleni sokudluliswa noma ukucutshungulwa. Inkohlakalo ingenzeka uma inqubo yokubhala iphazamiseka ngaphambi kokuthi iqedwe, ngendlela evimbela ukubhala ukuthi kuqedwe, ngokwesibonelo.ample uma amandla ephela. Kuyafaneleka kuleli phuzu ukunikeza isingeniso esisheshayo sendlela i-Linux OS (futhi, ngokwandisa, i-Raspberry Pi OS), ibhala idatha ukuze igcinwe. I-Linux ivamise ukusebenzisa izinqolobane zokubhala ukuze igcine idatha okufanele ibhalwe endaweni yokugcina. Lezi zinqolobane (zigcina okwesikhashana) idatha kumemori yokufinyelela okungahleliwe (i-RAM) kuze kube yilapho kufinyelelwa umkhawulo othile ochazwe ngaphambilini, okuyilapho konke okusele okubhalela endaweni yokugcina kwenziwa ngenkokhelo eyodwa. Le mikhawulo echazwe ngaphambilini ingaba isikhathi kanye/noma nosayizi ohlobene. Okwesiboneloampfuthi, idatha ingase ifakwe kunqolobane futhi ibhalwe kuphela kwisitoreji njalo ngemizuzwana emihlanu, noma ibhalwe kuphela lapho inani elithile ledatha liqoqiwe. Lezi zinhlelo zisetshenziselwa ukuthuthukisa ukusebenza: ukubhala ingxenye enkulu yedatha ngesikhathi esisodwa kuyashesha kunokubhala izingcezu eziningi zedatha.

Nokho, uma amandla elahlekile phakathi kwedatha egcinwe kunqolobane futhi ibhalwa ngaphandle, leyo datha iyalahleka. Ezinye izingqinamba ezingenzeka ziphakama kakhulu phansi kwenqubo yokubhala, ngesikhathi sokubhalwa kwedatha endaweni yokugcina. Kanye ucezu lwehadiwe (ngokwesiboneloample, isixhumi esibonakalayo sekhadi Ledijithali (i-SD) litshelwa ukuthi libhale idatha, kusathatha isikhathi esilinganiselwe ukuthi leyo datha igcinwe ngokoqobo. Futhi, uma ukwehluleka kwamandla kwenzeka kuleso sikhathi esifushane kakhulu, kuyenzeka ukuthi idatha ebhalwayo yonakale. Lapho uvala uhlelo lwekhompiyutha, kufaka phakathi i-Raspberry Pi, umkhuba ongcono kakhulu ukusebenzisa inketho yokuvala shaqa. Lokhu kuzoqinisekisa ukuthi yonke idatha egcinwe kunqolobane ibhalwa ngaphandle, nokuthi i-hardware ibe nesikhathi sokubhala idatha endaweni yokugcina. Amakhadi e-SD asetshenziswa iningi le-Raspberry Pi yamadivayisi mahle njengokushintshwa kwe-hard drive eshibhile, kodwa asengozini yokwehluleka ngokuhamba kwesikhathi, kuya ngokuthi asetshenziswa kanjani. Imemori ye-flash esetshenziswa emakhadini e-SD inomjikelezo wokubhala olinganiselwe wempilo yonke, futhi njengoba amakhadi esondela kulowo mkhawulo angase angathembeki. Amakhadi amaningi e-SD asebenzisa inqubo ebizwa ngokuthi i-wear leveling ukuze aqiniseke ukuthi ahlala isikhathi eside ngangokunokwenzeka, kodwa ekugcineni angahluleka. Lokhu kungaba kusuka ezinyangeni kuye eminyakeni, kuye ngokuthi ingakanani idatha ebhalelwe, noma (okubaluleke kakhulu) kusulwe ekhadini. Lokhu kuphila kungahluka kakhulu phakathi kwamakhadi. Ukwehluleka kwekhadi le-SD kuvame ukuboniswa ngokungahleliwe file ukonakala njengezingxenye zekhadi le-SD ziba ezingasebenziseki.

Kukhona ezinye izindlela zokuthi idatha yonakale, okuhlanganisa, kodwa kungagcini nje, indawo yokugcina enesici, iziphazamisi kusofthiwe yokubhala isitoreji (abashayeli), noma iziphazamisi kuzinhlelo zokusebenza ngokwazo. Ngezinjongo zaleli phepha elimhlophe, noma iyiphi inqubo okungenzeka ngayo ukulahleka kwedatha ichazwa njengomcimbi wenkohlakalo.

Yini engabangela ukuhlinzwa kokubhala?
Izinhlelo zokusebenza eziningi zenza uhlobo oluthile lokubhala endaweni yokugcina, isiboneloample imininingwane yokucushwa, izibuyekezo zesizindalwazi, nokunye okunjalo. Ezinye zazo files ingase ibe eyesikhashana, okungukuthi isetshenziswe kuphela ngenkathi uhlelo lusebenza, futhi ayidingi ukunakekelwa phezu komjikelezo wamandla; Nokho, basaholela ekubhaleni endaweni yokugcina. Noma ngabe uhlelo lwakho lokusebenza lungabhali noma iyiphi idatha, ngemuva i-Linux izohlale ibhala endaweni yokugcina, ikakhulukazi ibhala imininingwane yokugawula.

Izixazululo zezingxenyekazi zekhompuyutha

Nakuba kungenakho ngokuphelele ekukhishweni kwaleli phepha elimhlophe, kufanelekile ukusho ukuthi ukuvimbela ukwehla kwamandla okungalindelekile kuwukunciphisa okuvame ukusetshenziswa futhi okuqonda kahle ngokumelene nokulahlekelwa idatha. Amadivayisi afana nezinsiza zamandla ezingaphazamiseki (ama-UPS) aqinisekisa ukuthi ukunikezwa kwamandla kuhlala kuqinile futhi, uma amandla elahleka ku-UPS, kuyilapho emandleni ebhethri angatshela isistimu yekhompyutha ukuthi ukuphelelwa amandla kuseduze ukuze ukuvala shaqa kuqhubeke kahle ngaphambi kokuba ukunikezwa kwamandla okusekelayo kuphele. Ngenxa yokuthi amakhadi e-SD anokuphila okulinganiselwe, kungase kusize ukuba nohlelo olungena esikhundleni oluqinisekisa ukuthi amakhadi e-SD ayashintshwa ngaphambi kokuba abe nethuba lokufinyelela ekupheleni kwempilo.

Iqinile file izinhlelo

Kunezindlela ezihlukahlukene idivayisi ye-Raspberry Pi engenziwa ngayo lukhuni ngokumelene nemicimbi yenkohlakalo. Lokhu kuyahlukahluka emandleni azo okuvimbela inkohlakalo, isenzo ngasinye sinciphisa amathuba okuba yenzeke.

Ukunciphisa ukubhala
Ukunciphisa nje inani lokubhala izinhlelo zakho zokusebenza kanye ne-Linux OS kungaba nomthelela omuhle. Uma ugawula imithi eminingi, khona-ke amathuba okubhala okwenzeka ngesikhathi somcimbi wenkohlakalo ayakhula. Ukunciphisa ukungena kuhlelo lwakho lokusebenza kuncike kumsebenzisi wokugcina, kodwa ukungena ku-Linux nakho kungancishiswa. Lokhu kusebenza ikakhulukazi uma usebenzisa isitoreji esisekelwe ku-flash (isb i-EMMC, amakhadi e-SD) ngenxa yomjikelezo wabo wokuphila wokubhala olinganiselwe.

Ukushintsha izikhathi zokuzibophezela
Isikhathi sokwenza a file isistimu inani lesikhathi egcina ngalo idatha ngaphambi kokuthi ikopishe yonke endaweni yokugcina. Ukwandisa lesi sikhathi kuthuthukisa ukusebenza ngokuhlanganisa okuningi kokubhala, kodwa kungaholela ekulahlekeni kwedatha uma kukhona umcimbi wenkohlakalo ngaphambi kokubhalwa kwedatha. Ukunciphisa isikhathi sokuzinikela kuzosho amathuba amancane omcimbi wenkohlakalo oholela ekulahlekeni kwedatha, nakuba ungakuvimbeli ngokuphelele.
Ukushintsha isikhathi sokuzinikela se-EXT4 eyinhloko file system ku-Raspberry Pi OS, udinga ukuhlela i-\etc\fstab file echaza ukuthi kanjani file amasistimu afakwe ekuqaleni.
$sudo nano /etc/fstab

Engeza okulandelayo kokufakiwe kwe-EXT4 kumpande file uhlelo:

bophezela=

Ngakho-ke, i-fstab ingase ibukeke kanje, lapho isikhathi sokuzibophezela sisethelwe kumasekhondi amathathu. Isikhathi sokuzibophezela sizozenzakalelayo sibe imizuzwana emihlanu uma singasethiwe ngokuqondile.

Okwesikhashana file izinhlelo

Uma isicelo sidinga okwesikhashana file isitoreji, okungukuthi idatha esetshenziswa kuphela ngenkathi uhlelo lokusebenza lusebenza futhi kungadingeki ukuthi ilondolozwe lapho kuvalwe, khona-ke inketho enhle yokuvimbela ukubhala okuphathekayo kusitoreji ukusebenzisa isikhashana. file uhlelo, tmpfs. Ngoba lezi file amasistimu asuselwe ku-RAM (empeleni, kumemori ebonakalayo), noma iyiphi idatha ebhalelwe i-tmpfs ayilokothi ibhalwe endaweni yokugcina ephathekayo, ngakho-ke ayithinti ukuphila kwe-flash, futhi ayikwazi ukonakala ngenxa yesehlakalo senkohlakalo.
Ukudala indawo eyodwa noma ngaphezulu ye-tmpfs kudinga ukuhlela ifayela le-/etc/fstab file, elawula zonke file amasistimu ngaphansi kwe-Raspberry Pi OS. I-ex elandelayoample ithatha indawo yezindawo ezisekelwe kwisitoreji /tmp kanye /var/log ngezesikhashana file izindawo zesistimu. Eyesibili example, ethatha indawo yefolda yokugawulwa ejwayelekile, ikhawulela usayizi wefayela le file isistimu kuya ku-16MB.

tmpfs /tmp tmpfs okuzenzakalelayo,noatime 0 0
tmpfs /var/log tmpfs okuzenzakalelayo,noatime,size=16m 0 0

Kukhona neskripthi senkampani yangaphandle esiza ukusetha ukungena ku-RAM, esingatholakala ku-GitHub. Lokhu kunesici esengeziwe sokulahla amalogi asekelwe ku-RAM kudiski ngesikhathi esichazwe ngaphambilini.

Umsuka wokufunda kuphela file izinhlelo

Impande file uhlelo (rootfs) iyona file system kwi-disk partition lapho inkomba yempande itholakala khona, futhi iyona file uhlelo lapho zonke ezinye file amasistimu afakwa njengoba isistimu iqalwa phezulu. Ku-Raspberry Pi ingu-/, futhi ngokuzenzakalelayo itholakala ekhadini le-SD njengengxenye yokufunda/yokubhala ngokugcwele ye-EXT4. Kukhona nefolda ye-boot, efakwe njenge /boot futhi ihlukanisa i-FAT yokufunda/yokubhala. Ukwenza i-rootfs ifundeke KUPHELA kuvimbela noma yiluphi uhlobo lokufinyelela kokubhala kuyo, kuyenze iqine kakhulu ezenzakalweni zenkohlakalo. Kodwa-ke, ngaphandle kokuthi kuthathwe ezinye izinyathelo, lokhu kusho ukuthi akukho okungabhalela ku file system nhlobo, ngakho-ke ukulondoloza idatha yanoma yiluphi uhlobo kusuka kuhlelo lwakho lokusebenza kuya ku-rootfs kukhutshaziwe. Uma udinga ukugcina idatha kuhlelo lwakho lokusebenza kodwa ufuna i-rootfs efundwayo kuphela, indlela evamile ukungeza imemori ye-USB noma okufanayo okokugcina idatha yomsebenzisi.

QAPHELA
Uma usebenzisa i-swap file uma usebenzisa eyokufunda kuphela file system, uzodinga ukuhambisa ukushintshanisa file endaweni efundwayo/ebhalayo.

Imbondela file uhlelo

Imbondela file isistimu (i-overlayfs) ihlanganisa ezimbili file izinhlelo, phezulu file uhlelo kanye nephansi file uhlelo. Lapho igama likhona kokubili file izinhlelo, into phezulu file uhlelo luyabonakala ngenkathi into engezansi file isistimu ifihliwe noma, esimweni sezinkomba, ihlanganiswe nento engaphezulu. I-Raspberry Pi inikeza inketho ku-raspi-config ukuze unike amandla ukumbondelana. Lokhu kwenza ama-rootfs (aphansi) afundeke kuphela, futhi kwakha phezulu okusekelwe ku-RAM file uhlelo. Lokhu kunikeza umphumela ofana kakhulu nowokufunda kuphela file system, nazo zonke izinguquko zomsebenzisi ezilahlekile ekuqaliseni kabusha. Ungakwazi ukunika amandla ukumbondelana usebenzisa umugqa womyalo we-raspi-config noma usebenzisa uhlelo lokusebenza lokucushwa kwe-Raspberry Pi yedeskithophu kumenyu ethi Okuthandwayo.

Kukhona nokunye ukusetshenziswa kokumbondelana okungavumelanisa izinguquko ezidingekayo ukusuka phezulu ukuya phansi file uhlelo ngeshejuli enqunywe kusengaphambili. Okwesiboneloample, ungase ukopishe okuqukethwe kwefolda yasekhaya yomsebenzisi ukusuka phezulu ukuya kwehlise njalo ngamahora ayishumi nambili. Lokhu kukhawulela inqubo yokubhala esikhathini esifushane kakhulu, okusho ukuthi inkohlakalo mancane kakhulu amathuba okuba inkohlakalo, kodwa kusho ukuthi uma amandla elahlekile ngaphambi kokuvumelanisa, noma iyiphi idatha ekhiqizwa kusukela kokugcina ilahleka. I-pSLC kumamojula eCompute Inkumbulo ye-EMMC esetshenziswa kumadivayisi we-Raspberry Pi Compute Module yi-MLC (Multi-Level Cell), lapho iseli lememori ngalinye limelela amabhithi angu-2. I-pSLC, noma i-pseudo-Single Level Cell, iwuhlobo lobuchwepheshe benkumbulo ye-NAND flash enganikwa amandla kumadivayisi esitoreji se-MLC ahambisanayo, lapho iseli ngalinye limelela ibhithi elilodwa kuphela. Iklanyelwe ukunikeza ibhalansi phakathi kokusebenza nokukhuthazela kwe-SLC flash kanye nokusebenza kahle kwezindleko kanye nomthamo ophezulu we-MLC flash. I-pSLC inokukhuthazela okuphezulu kokubhala kune-MLC ngoba ukubhala idatha kumaseli akuvamile kunciphisa ukuguga. Nakuba i-MLC ingase inikeze cishe imijikelezo yokubhala eyi-1 kuya kweziyi-3,000, i-pSLC ingafinyelela izinombolo eziphakeme kakhulu, isondela emazingeni okubekezela e-SLC. Lokhu kukhuthazela okwandisiwe kuhumushela esikhathini eside sempilo yamadivayisi asebenzisa ubuchwepheshe be-pSLC uma kuqhathaniswa nalawo asebenzisa i-MLC ejwayelekile.

I-MLC ibiza kakhulu kunenkumbulo ye-SLC, kodwa ngenkathi i-pSLC inikeza ukusebenza okungcono nokukhuthazela kune-MLC ehlanzekile, ikwenza lokho ngezindleko zomthamo. Idivayisi ye-MLC elungiselelwe i-pSLC izoba nohhafu womthamo (noma ngaphansi) engaba nawo njengedivayisi ye-MLC evamile njengoba iseli ngalinye ligcina ibhithi elilodwa kuphela esikhundleni sokubili noma ngaphezulu.

Imininingwane yokusetshenziswa

I-pSLC isetshenziswa ku-EMMC njengendawo Yomsebenzisi Ethuthukisiwe (eyaziwa nangokuthi isitoreji Esithuthukisiwe). Ukuqaliswa kwangempela Kwendawo Yomsebenzisi Ethuthukisiwe akuchazwanga ezingeni le-MMC kodwa ngokuvamile kuyi-pSLC.

Indawo Yomsebenzisi Ethuthukisiwe ingumqondo, kuyilapho i-pSLC iwukuqaliswa.

I-pSLC ingenye yezindlela zokusebenzisa Indawo Yomsebenzisi Ethuthukisiwe.
Ngesikhathi sokubhala, i-EMMC esetshenziswe ku-Raspberry Pi Compute Modules isebenzisa Indawo Yomsebenzisi Ethuthukisiwe isebenzisa i-pSLC.

Asikho isidingo sokumisa yonke indawo yomsebenzisi we-EMMC njengendawo Yomsebenzisi Ethuthukisiwe.
Ukuhlela indawo yenkumbulo ukuthi ibe Indawo Yomsebenzisi Ethuthukisiwe kuwumsebenzi wesikhathi esisodwa. Lokho kusho ukuthi ngeke kuhlehliswe.

Ukuyivula
I-Linux inikeza isethi yemiyalo yokukhohlisa izingxenye ze-EMMC kuphakheji ye-mmc-utils. Faka i-Linux OS ejwayelekile kudivayisi ye-CM, bese ufake amathuluzi ngendlela elandelayo:

sudo apt ukufaka mmc-utils

Ukuze uthole ulwazi mayelana ne-EMMC (lo myalo ufaka okuncane njengoba kunolwazi oluningi olungaboniswa):

sudo mmc extcsd funda /dev/mmcblk0 | Ngaphansi

ISEXWAYISO
Imisebenzi elandelayo ingeyesikhathi esisodwa - ungayisebenzisa kanye futhi ayikwazi ukuhlehliswa. Kufanele futhi uwaqalise ngaphambi kokuthi kusetshenziswe Imojula Yekhompyutha, njengoba azosula yonke idatha. Amandla e-EMMC azokwehliswa abe uhhafu yenani langaphambilini.

Umyalo osetshenziswe ukuvula i-pSLC uthi mmc enh_area_set, odinga izinhlaka ezimbalwa ezitshela ukuthi ingakanani indawo yememori okufanele inikwe amandla i-pSLC. I-ex elandelayoample isebenzisa yonke indawo. Sicela ubheke kusizo lomyalo we-mmc (man mmc) ukuze uthole imininingwane yokuthi usetshenziswa kanjani isethi engaphansi ye-EMMC.

Ngemva kokuthi idivayisi iqale kabusha, uzodinga ukufaka kabusha isistimu yokusebenza, njengoba ukunika amandla i-pSLC kuzosula okuqukethwe kwe-EMMC.

Isoftware ye-Raspberry Pi CM Provisioner inenketho yokusetha i-pSLC ngesikhathi senqubo yokuhlinzeka. Lokhu kungatholakala ku-GitHub ku https://github.com/raspberrypi/cmprovision.

Ngaphandle kwedivayisi file amasistimu / ukubhutha kwenethiwekhi
I-Raspberry Pi iyakwazi ukuqala ngoxhumo lwenethiwekhi, ngokwesiboneloampusebenzisa i-Network File Uhlelo (NFS). Lokhu kusho ukuthi uma idivayisi isiqede okokuqalatage boot, esikhundleni sokulayisha i-kernel nempande yayo file Uhlelo olusuka ekhadini le-SD, lilayishwa lisuka kuseva yenethiwekhi. Uma usugijima, konke file imisebenzi isebenza kuseva hhayi ekhadini le-SD lendawo, elingathathi indima eyengeziwe ezinqubeni.
Izixazululo zamafu
Namuhla, imisebenzi eminingi yasehhovisi yenzeka esipheqululini, yonke imininingwane igcinwa ku-inthanethi emafini. Ukugcina isitoreji sedatha singekho ekhadini le-SD ngokusobala kungathuthukisa ukwethembeka, ngezindleko zokudinga uxhumano oluhlala luvuliwe ku-inthanethi, kanye nezindleko ezingaba khona ezivela kubahlinzeki bamafu. Umsebenzisi angasebenzisa ukufakwa okugcwele kwe-Raspberry Pi OS, ngesiphequluli esilungiselelwe i-Raspberry Pi, ukuze afinyelele noma yiziphi izinsiza zamafu ezivela kubahlinzeki abafana ne-Google, i-Microsoft, i-Amazon, njll. Enye indlela ingomunye wabahlinzeki bamaklayenti amancane, omiselela i-Raspberry Pi OS nge-OS/uhlelo lokusebenza olusebenzisa izinsiza ezigcinwe kuseva emaphakathi esikhundleni sekhadi le-SD. Amaklayenti azacile asebenza ngokuxhuma ukude endaweni yekhompuyutha esekwe kuseva lapho kugcinwa khona izinhlelo zokusebenza eziningi, idatha ebucayi, nenkumbulo.
