Igama
vcreate - qalisa idiski okanye ukwahlula ukusetyenziswa yi-LVM
Isiqendu
pvcate [ -d | --debug ] [ -f [ f ] | - ukusebenza [- force ] ] [ -y | - ] [ -h | --help ] [ -v | -verbose ] [ -V | --verver ] I- PhysicalVolume [ PhysicalVolume ...]
Inkcazo
I-pvcreate iqalisa i- PhysicalVolume ukuze isebenziswe kamva yi-Logical Volume Manager (LVM). I- PhysicalVolume nganye ingaba isahlulelo sedisk, idiski yonke, i-meta ifowuni, okanye ifayile yeloopback. Kwi- DOS disk partitions, i-id yokuhlukanisa imele ibekwe kwi-0x8e isebenzisa i- fdisk (8), cfdisk (8), okanye ilingana. Iifayile ezidityanisiweyo kuphela ietafile zokwahlukana kufuneka zicimwe, eziza kutshabalalisa yonke idatha kwi disk. Oku kunokwenziwa ngokukhupha icandelo lokuqala kunye:
dd = = / dev / zero = = I- PhysicalVolume bs = 512 count = 1
Qhubeka kunye ne- vgcreate (8) ukudala iqela elitsha levolumu kwi- PhysicalVolume , okanye vgextend (8) ukufaka iPhysicMolume kwiqela levolumu ekhoyo.

-d , --debug
Inika amandla ukuveliswa kokungekho kwemveliso (xa kuqulunqwe nge-DEBUG).
-f , - ukusebenza
Ukunyanzela ukudala ngaphandle kwesiqinisekiso. Awukwazi ukuphinda uvuselele (ukuvuselela kwakhona) umthamo womzimba weqela elikhoyo levolumu. Ngoxakeko unokwenza umgangatho wokuziphatha ngale ndlela. Akunakwenzeka kwimeko apho ungayilungisa umthamo womzimba osebenzayo kunye nalo myalelo.
-s , - nceda
Ugqitha ubungakanani bomthamo womzimba oqhelekileyo ukubuyiswa. Uncedo kwiimeko ezinqabileyo apho eli xabiso libi. Eyona nto iluncedo kumaninzi amakhulu okuba yinkohlakalo yokufikelela kwi-2 iTababyes - 1 Kilobyte kumadivayisi amancinci ngenjongo yokuvavanya kuphela apho kungenako ukufikelela kwangempela kwedatha kwimiqulu enengqiqo efunekayo. Ukuba unqwenela ukudala ubuninzi obuxhasiweyo, sebenzisa "pvcreate -s 2147483647k PhysicalVolume [PhysicalVolume ...]". Zonke ezinye izixhobo zeLVM ziya kusebenzisa olu bukhulu ngaphandle kwe- lvmdiskscan (8)

Phendula ewe kuyo yonke imibuzo.
-h , -help
Phrinta umyalezo wokusetyenziswa kwisiphumo esisezantsi kwaye uphume ngempumelelo.
-v , --verbose
Unika ulwazi lwexesha lokusebenzisa i-verbose malunga nemisebenzi ye-pvcreate.
-V , --version
Phrinta inombolo yenguqu kwimveliso eqhelekileyo kwaye uphume ngempumelelo.
Umzekelo
Qalisa isahlulo # 4 kwi disk yesithathu disk kunye ne-disk yesihlanu ye- SCSI disk yokusetyenziswa kweLVM kamva:
pvcreate / dev / sdc4 / dev / sde
