A RAID 1 array muaj tib cov ntaub ntawv ntawm ob lossis ntau dua disks. Kuj tseem hu ua mirrored array, RAID 1 yog ib qho ntawm Redundant Array of Independent Disks (RAID) qib txhawb nqa los ntawm OS X thiab Disk Utility. Hauv RAID 1 array, koj muab ob lossis ntau dua disks raws li cov teeb pom kev zoo. Tom qab koj tsim lub teeb tsom iav, koj Mac pom nws ua ib lub disk drive.
Information in this article use to OS X Yosemite (10.10) through OS X Leopard (10.5).
Yuav Ua Li Cas Koj Mac Ua Haujlwm Nrog RAID 1 Array
Thaum koj Mac sau cov ntaub ntawv rau lub teeb tsom iav, nws duplicates cov ntaub ntawv hla txhua tus tswv cuab ntawm lub teeb kom ntseeg tau tias cov ntaub ntawv tiv thaiv kev poob yog tias ib qho nyuaj tsav hauv RAID 1 teeb ua tsis tiav. Tsuav yog ib tus tswv cuab ntawm cov teeb tsa tseem ua haujlwm, koj Mac tseem ua haujlwm ib txwm ua, muab kev nkag mus rau koj cov ntaub ntawv tiav.
Koj tuaj yeem tshem tawm cov tsav nyuaj los ntawm RAID 1 teeb thiab hloov lub hard drive nrog lub hard drive tshiab lossis kho dua tshiab. Lub RAID 1 teeb ces rov tsim nws tus kheej, luam cov ntaub ntawv los ntawm cov txheej txheem uas twb muaj lawm mus rau tus tswv cuab tshiab. Koj tuaj yeem txuas ntxiv siv koj Mac thaum lub sijhawm rov tsim kho dua vim nws tshwm sim hauv keeb kwm yav dhau.
Vim li cas RAID 1 Tsis yog thaub qab
Txawm hais tias nws feem ntau siv los ua ib feem ntawm lub tswv yim thaub qab, RAID 1 los ntawm nws tus kheej tsis yog qhov hloov pauv zoo rau thaub qab koj cov ntaub ntawv nrog Mac thaub qab software lossis lwm txoj hauv kev.
Txhua cov ntaub ntawv sau rau RAID 1 teeb yog tam sim ntawd theej rau txhua tus tswv cuab ntawm lub teeb; tib yam muaj tseeb thaum koj tshem tawm cov ntaub ntawv. Thaum koj rho tawm cov ntaub ntawv, cov ntaub ntawv ntawd raug tshem tawm ntawm txhua tus tswv cuab ntawm RAID 1 teeb. Raws li qhov tshwm sim, RAID 1 tsis tso cai rau koj rov qab cov ntaub ntawv qub qub, xws li version ntawm cov ntaub ntawv koj tau kho lub lim tiam dhau los.
kab hauv qab
Siv RAID 1 daim iav ua ib feem ntawm koj lub tswv yim thaub qab ua kom lub sijhawm ua haujlwm siab tshaj plaws thiab kev ntseeg tau. Koj tuaj yeem siv RAID 1 rau koj tsav pib, cov ntaub ntawv tsav, lossis koj tus tsav thaub qab.
Yam Koj Yuav Tsum Tau Ua RAID 1 Daim iav
Tsim kom muaj RAID 1 daim iav rau koj Mac, koj xav tau ob peb yam yooj yim.
- OS X Leopard (10.5) through OS X Yosemite (10.10).
- Disk Utility, uas suav nrog OS X.
- ob lossis ntau dua hard drives. Tus txheej txheem ntawm kev tsim RAID 1 mirrored teev erases tag nrho cov ntaub ntawv ntawm lub hard drives. Siv cov hard drives uas yog tib yam tsim thiab qauv yog pom zoo tab sis tsis tas yuav tsum tau.
- Ib qho lossis ntau qhov chaw tsav tsheb Mac Pro cov neeg siv yuav muaj cov tsav sab hauv muaj. Txhua leej txhua tus xav tau ib los yog ntau tshaj sab nraud tsav enclosures. Yog tias koj siv ntau lub kaw lus tsav, lawv yuav tsum yog tib yam tsim thiab qauv lossis tsawg kawg muaj tib hom kev sib cuam tshuam, xws li FireWire, USB, Thunderbolt, lossis SATA.
txheej txheem ntawm kev tsim cov txheej txheem RAID yog qhov yooj yim thiab tsis siv sijhawm ntau, tab sis tshem tawm cov tsav hauv RAID teeb siv qhov kev xaiv Zero Out Data yog cov txheej txheem siv sijhawm uas ua kom muaj kev ntseeg siab tshaj plaws.
Thaum cov lus qhia no ua haujlwm rau OS X Yosemite thiab cov qauv ua ntej ntawm lub operating system, qee cov kauj ruam, npe, lossis cov duab qhia hauv kab lus no yuav txawv rau koj lub operating system. Kua tshem tawm lub peev xwm tsim RAID los ntawm OS X El Capitan tab sis xa rov qab nws, hauv hom hloov kho hauv OS X Sierra. Txhawm rau tsim RAID array hauv El Capitan, siv tus thib peb app xws li SoftRAID Lite los tsim thiab tswj RAID arrays.
Luag cov tsav
Lub hard drives koj siv los ua cov tswv cuab ntawm RAID 1 daim iav teeb yuav tsum tau muab tshem tawm ua ntej.
Vim tias koj tab tom tsim RAID 1 teeb kom koj cov ntaub ntawv tseem tuaj yeem siv tau, siv sijhawm me ntsis ntxiv thiab siv ib qho ntawm Disk Utility Security Options, Zero Out Data, uas erases txhua hard drive.
Thaum koj xoom tawm cov ntaub ntawv, koj yuam lub hard drive los xyuas cov ntaub ntawv tsis zoo thaum lub sijhawm tshem tawm cov txheej txheem thiab kos cov blocks tsis zoo li tsis siv. Qhov no txo qis qhov yuav poob cov ntaub ntawv vim qhov ua tsis tiav ntawm lub hard drive. Nws kuj tseem ua kom lub sijhawm nws siv sijhawm los tshem tawm cov tsav los ntawm ob peb feeb mus rau ib teev lossis ntau dua rau ib lub tsav.
Luag cov Tsav Tsheb Siv Zero Out Cov Ntaub Ntawv Xaiv
Luag txhua qhov tsav koj npaj yuav siv hauv RAID 1 daim iav teeb.
- Txuas lub hard drives uas koj npaj siab yuav siv rau koj lub Mac thiab txhawb zog rau lawv.
- Launch Disk Utility, nyob ntawm Applications > Utilities.
-
Xaiv lub hard drive koj yuav siv hauv RAID 1 daim iav teeb los ntawm cov npe nyob rau sab laug pane. Xaiv lub tsav, tsis yog lub npe ntim uas tshwm nyob hauv qab lub npe tsav.

Tsim RAID 1 Daim iav Teeb
Tom qab koj tshem tawm cov tsav uas koj npaj yuav siv rau RAID 1 teeb, koj npaj tsim daim iav teeb.
Yog tias koj siv macOS Big Sur, Catalina, lossis Mojave, koj yuav tsim lub disk teeb los ntawm kev qhib Disk Utility thiab xaiv File > RAID Assistant . Xaiv hom kev teeb tsa thiab xaiv koj lwm txoj kev xaiv, tom qab ntawd xaiv Tsim > Done.
- Launch Disk Utility yog tias daim ntawv thov tsis qhib.
-
Xaiv ib qho ntawm cov hard drive uas koj npaj yuav siv hauv RAID 1 daim iav teeb los ntawm Drive/Volume cov npe nyob rau sab laug pane ntawm Disk Utility window.
Image -
Click the RAID tab.

Xaiv Daim iav RAID teeb as the Raid Type.
Image -
Click Options.
Image - Tsim RAID thaiv qhov loj. Qhov block loj nyob ntawm hom ntaub ntawv koj npaj khaws cia rau ntawm RAID 1 daim iav teeb. Rau kev siv dav dav, xav txog qhov loj me xws li 256K lossis loj dua txhawm rau txhim kho qhov ua tau zoo ntawm RAID.
-
Xaiv Tsis Siv Neeg RAID daim iav teeb rau RAID 1 daim iav teeb koj tab tom tsim kom rov tsim kho nws tus kheej yog tias cov tswv cuab ntawm RAID dhau los ua tsis sib xws.
Lub tsev tsis siv neeg yuav tsis yog lub tswv yim zoo thaum koj siv RAID 1 daim iav teeb rau "Disk Utility RAID tab nrog Tsim qhov tseem ceeb" id=mntl-sc-block-image_1-0-13 / > alt="
- A Tsim RAID daim ntawv ceeb toom poob qis kom nco ntsoov tias tag nrho cov ntaub ntawv ntawm cov tsav uas ua rau RAID array tab tom yuav raug tshem tawm. Nyem Create mus txuas ntxiv.
Thaum lub sijhawm tsim RAID 1 daim iav teeb, Disk Utility renames tus kheej ntim uas ua rau RAID teeb rau "RAID Slice." Nws mam li tsim RAID 1 daim iav teeb thiab mounts nws li ib txwm hard drive ntim ntawm koj Mac's desktop.
Tag nrho lub peev xwm ntawm RAID 1 daim iav koj tsim yog sib npaug rau cov tswv cuab tsawg tshaj plaws ntawm cov teeb, rho tawm qee qhov nyiaj siv ua haujlwm rau RAID khau raj cov ntaub ntawv thiab cov ntaub ntawv qauv.
Tam sim no koj tuaj yeem kaw Disk Utility thiab siv koj daim iav RAID 1 raws li nws yog lwm qhov disk ntim ntawm koj Mac.
Siv Koj Tus Tshiab RAID 1 Daim iav Teeb
OS X kho RAID teeb tsa tsim nrog Disk Utility raws li tus qauv hard drive ntim. Raws li qhov tshwm sim, koj tuaj yeem siv lawv ua cov ntim pib, ntim cov ntaub ntawv, lossis cov ntim thaub qab.
Tam sim no koj tau ua tiav tsim RAID 1 daim iav teeb, ntawm no yog qee cov lus qhia rau nws siv.
Hot Spares
Koj tuaj yeem ntxiv ntim ntxiv rau RAID 1 daim iav txhua lub sijhawm, txawm tias tom qab tsim RAID array. Drives ntxiv tom qab RAID array raug tsim yog hu ua cov khoom kub. RAID array tsis siv cov khoom kub tshwj tsis yog tias tus tswv cuab nquag ntawm lub teeb ua tsis tiav.
Thaum lub sijhawm ntawd, RAID array cia li siv cov khoom kub kub hloov pauv rau lub hard drive tsis ua haujlwm thiab pib ua cov txheej txheem rov tsim kho kom hloov cov khoom kub kub rau cov tswv cuab ntawm cov array. Thaum koj ntxiv qhov kub thiab txias, lub hard drive yuav tsum sib npaug los yog loj dua tus tswv cuab tsawg tshaj plaws ntawm RAID 1 daim iav teeb.
Rebuilding
Kev tsim kho tuaj yeem tshwm sim txhua lub sijhawm RAID 1 daim iav teeb tsa tsav dhau los ntawm synchronization-cov ntaub ntawv ntawm tus tsav tsis sib xws rau lwm tus tswv cuab ntawm lub teeb. Thaum qhov no tshwm sim, cov txheej txheem rov tsim kho pib tau txais, piv txwv tias koj xaiv qhov kev xaiv rov tsim kho tsis siv neeg thaum lub sijhawm RAID 1 daim iav teeb tsa txheej txheem tsim. Thaum lub sij hawm rebuilding txheej txheem, lub out-of-sync disk muaj cov ntaub ntawv rov qab mus rau nws los ntawm cov seem ntawm cov tswv cuab.
Cov txheej txheem rov tsim kho yuav siv sijhawm. Thaum koj tseem tuaj yeem siv koj lub Mac li qub thaum lub sijhawm rov tsim kho, koj yuav tsum tsis txhob pw lossis kaw lub Mac thaum lub sijhawm txheej txheem.
Rov tsim kho tuaj yeem tshwm sim vim yog vim li cas dhau lub hard drive tsis ua haujlwm. Qee qhov xwm txheej tshwm sim uas ua rau rov tsim kho dua tshiab yog OS X tsoo, lub zog tsis ua haujlwm, lossis ua tsis raug rau Mac.
