Kaw cov pib pib thaum thauj khoom Ubuntu

Pib qib - RAM cov ntaub ntawv system, uas yog siv los pib cov haujlwm ua haujlwm raws li Linux Kernel. Thaum txhim kho OS, tag nrho cov tsev qiv ntawv, cov khoom siv thiab cov teeb tsa cov ntaub ntawv tau sib txuas, tom qab cov ntaub ntawv tshwj xeeb kis tau rau lub kaw lus, qhov twg pib ntawm lub system txuas ntxiv. Qee zaum Ubuntu faib cov neeg siv ntsej muag uas koj qhib lub computer, lawv poob rau hauv kev tswj hwm ntawm FS no tsis muaj peev xwm thauj khoom ntxiv. Qhov no yog vim kev puas tsuaj rau tus dej pib thiab tau rov qab kho txoj kev yooj yim.

Kho qhov yuam kev nrog kev rub tawm rau initramramfs thaum koj pib Ubuntu

Feem ntau, cov teeb meem hauv kev txiav txim siab yog cuam tshuam nrog kev ua tsis tiav, thiab thaum koj sim tawm ntawm qhov pib, thiab koj sim tawm ntawm cov lus txib, cov ntawv sau zoo nkaus li hauv qab no:

(Piv txwv li, tsis muaj kev xaiv los yog -p -p) FSCK tawm nrog cov xwm txheej cov cai 4. Dev / MacPERU - VG-paus yuav tsum muaj phau ntawv FSCK.

Yog tias qhov xwm txheej zoo li no, txoj haujlwm zoo tshaj plaws yuav rov ua haujlwm ntawm SuperBlock, thiab qhov no tuaj yeem ua raws li hauv qab no:

1. Thauj cov duab ISO nrog tib cov Ubuntu, raws li tau ntsia rau ntawm lub khoos phis tawm, los ntawm lub vev xaib raug cai thiab tsim lub flash drash drash. Koj tuaj yeem kawm paub ntau ntxiv txog cov txheej txheem no hauv lwm tsab xov xwm ntawm cov ntawv txuas hauv qab no.

4. Tshawb nrhiav cov txheej txheem sib tshooj ntawm lub hard disk nrog cov txheej txheem teeb tsa los ntawm kev nkag mus rau Sudio FDISK -L | GEP -TP -EV '.



5. Hauv kab tshiab koj yuav pom kev tsim qauv, xws li / dev / sda1. Nco ntsoov nws, vim hais tias yav tom ntej nws yuav tsum tau kho qhov yuam kev.



6. Khiav cov txheej txheem hloov chaw rau txhua tus superblocks uas twb muaj lawm los ntawm sudo dumpe2fs / dev / sda1 | Grep superblock. Hauv txhua lub superblock, qee qhov ntawm cov ntaub ntawv me me ntawm cov ntaub ntawv metadata tau khaws cia, yog li tsis ua haujlwm thiab ua haujlwm OS thauj khoom tsis ua haujlwm OS.



7. Nyob rau hauv cov kab tshiab, tom qab ua kom cov lus txib, cov npe ntawm txhua tus neeg tam sim no nyob hauv Suplocklock seem yuav tshwm sim.



8. Ua ib qho piv txwv ib thaiv twg, piv txwv li, thawj zaug. Nrog nws, FS yog rov qab los. Lub community launch ntawm txoj haujlwm no yog nqa tawm tom qab nkag mus rau Sudo FSck -b 32768 yog tus naj npawb ntawm superblock, A / Dev / SDA1 yog qhov xav tau ntawm lub hard disk.

   

   Nrog rau kev xaiv-siab tag nrho cov kev hloov yuav tau txais, thiab thaum tus txheej txheem ua tiav, cov lus qhia hauv qab no yuav raug tshwm rau ntawm qhov screen:

   FSCK 1.40.2 (12-Jul-2007) E2FSck 1.40.2 (12-Jul-200) / dev / sda1 tsis tau unmuned, khij yuam. Hla Dhau 1: Kev kuaj cov inodes, block, thiab SIZES PIB 3: Kev kuaj xyuas cov ntaub ntawv txuas ntxiv 5: Kev kuaj xyuas cov ntaub ntawv sib txuas dawb rau cov pab pawg # 241 (32254, suav = 32253) Cov. Kho? Yog Dawb Block tsis ncaj ncees lawm rau pab pawg # 362 (32254, suav = 32248). Kho? Yog Dawb Block tsis ncaj ncees lawm rau pab pawg # 368 (32254, suav = 27774). Kho? Yog ... / dev / sda1: ***** Cov Ntaub Ntawv raug hloov kho ***** / dev / sda1: 59776 files (0.6% tsis yog-rauv), 3604682/61059048 blocks Cov.

9. Nws tseem nyob rau mount sudo mount / dev / sda1 / mnt system ntu.



10. Tom ntej no, mus rau nws ntawm CD / MNT kom txhua lo lus txib tau ua ncaj qha los ntawm phau ntawv kawm nws tus kheej.



11. Saib cov ntsiab lus ntawm FS ntawm Sudo Mkdir Test LS -L. Kev ua tiav kev ua tiav ntawm txoj haujlwm no qhia tias kev kho kom rov qab tau dhau los tau dhau mus ua tiav thiab tuaj yeem rov pib dua.

Qee zaum txawm tias tom qab kev kho tau zoo ntawm cov teeb meem tau txiav txim siab, kev sib xyaw ua ke tau ua yuam kev thaum khiav lub operating system. Feem ntau cov feem ntau lawv tau cuam tshuam nrog kev rhuav tshem ntawm tus qauv grub loader. Yog li ntawd, nws yuav tsim nyog los txuas ntxiv cov qauv no. Cov Ntawv Qhia Txog Kev Tso Cai rau hauv txoj haujlwm ua haujlwm li cas los ntawm kev kho khau raj, nrhiav cov khoom ntxiv.

Niaj hnub no peb tau tham txog cov kev daws teeb meem tshaj plaws hauv initramfs hauv initramfs, tab sis qhov no tsis txhais tau tias txoj kev yog universal. Thaum muaj kev ua yuam kev ntawm lwm tus cwj pwm, piav qhia nws nyob rau hauv cov lus, thiab peb yuav sim muab txoj kev daws teeb meem rau qhov xwm txheej no.
