Lub npe
pvcreate - pib lub disk lossis muab faib rau kev siv LVM
Synopsis
pvcreate [ -d | --debug ] [ -f [ f ] | - ua ke [ --force ] ] [ -y | --yes ] [ -h | - pabcuam ] [ -v | --tej lwm yam ] [ -V | --version ] PhysicalVolume [ PhysicalVolume ...]
Kev piav qhia
pvcreate initializes PhysicalVolume rau tom qab siv los ntawm cov Thawv Ntev Luam Teeb (LVM). Txhua tus PhysicalVolume tuaj yeem ua disk faib, tag nrho disk, ntaus ntawv meta, los yog cov ntaub ntawv loopback. Rau DOS disk partitions, qhov muab faib tus ID yuav tsum tau teem rau 0 x 8e siv fdisk (8), cfdisk (8), los yog sib npaug. Rau tag nrho disk li ntawm tsuas yog cov lus muab faib yuav tsum tau erased, uas yuav ua kom puas tag nrho cov ntaub ntawv ntawm qhov disk. Qhov no yuav ua tau los ntawm zeroing tus thawj sector nrog:
dd yog = / dev / zero ntawm = PhysicalVolume bs = 512 suav = 1
Mus nrog vgcreate (8) los tsim ib pawg ntim tshiab rau PhysicalVolume , los yog vgextend (8) ntxiv PhysicalVolume rau ib pab pawg coob uas muaj ntim ua haujlwm.
Xaiv
-d , --debug
Pab kom ntxiv debugging output (yog compiled nrog DEBUG).
-f , - ua ke
Force lub creation tsis muaj kev pom zoo. Koj tsis tuaj yeem rov tsim dua (rov ua dua) ib ntu ntawm lub cev uas muaj cov ntim khoom qub uas twb muaj lawm. Thaum muaj xwm ceev koj tuaj yeem hla dhau tus cwj pwm no nrog -ff. Nyob rau hauv tsis muaj cov ntaub ntawv tau koj initialize ib lub cev muaj zog ntim nrog cov lus txib no.
-siv , -size
Overrides qhov luaj li cas ntawm lub cev ntim uas feem ntau tau txais rov qab. Pab tau nyob rau hauv cov ntaub ntawv tsawg tsawg uas qhov nqi no tsis yog. Pab ntxiv rau fake loj lub cev tag nrho txog li 2 Terabyes - 1 Kilobyte rau cov khoom siv me me rau kev soj ntsuam tsuas yog qhov twg tsis muaj kev nkag mus rau cov ntaub ntawv hauv tsim tsim kom muaj nyiaj txaus. Yog tias koj xav tsim qhov siab tshaj plaws, siv "pvcreate -s 2147483647k PhysicalVolume [PhysicalVolume ...]". Tag nrho lwm yam LVM cov cuab yeej yuav siv qhov luaj li no nrog rau kev zam ntawm lvmdiskscan (8)
-yog , -yes
Teb rau txhua lo lus nug.
-h , - pabcuam
Sau cov lus siv rau kev tso zis thiab tawm tau zoo.
-v , - tshaj tawm
Muab cov ntaub ntawv qhia txog kev ua pvcreate cov kev ua ub no.
-V , --version
Sau cov qauv zauv rau cov zis tawm thiab tawm tau zoo.
Piv txwv
Initialize muab faib # 4 ntawm SCSI thib peb thiab tag nrho tsib SCSI disk tom qab siv LVM:
pvcreate / dev / sdc4 / dev / sde
