Igama
pvcreate - qalisa i-disk noma ukwahlukana okusetshenziswa yi-LVM
Isiqubulo
pvcate [ -d | --debug ] [ -f [ f ] | - sebenzisa [- ukusebenza ] ] [ -y | - bona ] [ -h | --help ] [ -v | - vele ] [ -V | --version ] PhysicalVolume [ PhysicalVolume ...]
Incazelo
I-pvcreate iqalisa i- PhysicalVolume ukuze isebenziswe kamuva yi-Logical Volume Manager (LVM). I- PhysicalVolume ngayinye ingaba ukuhlukaniswa kwedisk, i-disk yonke, idivayisi yedatha, noma ifayela loopback. Ukuze uthole izingxenye zeDOS disk, i-id yokuhlukanisa kufanele isethwe ku-0x8e usebenzisa i- fdisk (8), cfdisk (8), noma okulinganayo. Kuwo wonke amadivaysi e-disk kuphela ithebula lokuhlukanisa kumele lisuswe, okuzobhubhisa ngempumelelo yonke idatha kuleso disk. Lokhu kungenziwa ngokukhipha umkhakha wokuqala nge:
dd uma = / dev / zero of = PhysicalVolume bs = 512 count = 1
Qhubeka ne- vgcreate (8) ukwakha iqembu elisha levolumu ku- PhysicalVolume , noma i- vgextend (8) ukwengeza i- PhysicalVolume eqenjini levolumu elikhona.
Izinketho
-d , --debug
Inika amandla okukhipha okungeziwe kokukhipha (uma kuhlanganiswa ne-DEBUG).
-f , - ukusebenza
Qinisekisa indalo ngaphandle kokuqinisekisa. Awukwazi ukuphinda uvuselele kabusha (ukuvuselela kabusha) ivolumu yomzimba eqenjini levolumu elikhona. Esimweni esiphuthumayo ungangena ngaphezulu kwalokhu kuziphatha nge-. Akukho cala lecala ongaqala ngalo ivolumu yomzimba osebenzayo nalo myalo.
-s , -size
Iqeqa ubungako bomthamo womzimba ovame ukubuyiselwa. Kuwusizo esimweni esingavamile lapho leli xabiso lingalungile. Okuwusizo kakhulu kumanani amakhulu amakhulu emvelo we-Terabyes angu-2 - i-Kilobyte kumadivayisi amancane okuhloswa kuphela uma kungekho ukufinyelela kwangempela kwedatha kuminyenti enengqondo edingekayo. Uma ufisa ukwakha okungaphezulu okusekelwe, sebenzisa i- "pvcreate -s 2147483647k PhysicalVolume [PhysicalVolume ...]". Wonke amanye amathuluzi we-LVM azosebenzisa lobu bukhulu ngaphandle kwe- lvmdiskscan (8)
-y , - yebo
Phendula yebo kuyo yonke imibuzo.
-h , --help
Phrinta umlayezo wokusebenzisa ekuphumeni okujwayelekile futhi uphume ngempumelelo.
-v , - ukuphikisa
Inikeza imininingwane ye-verbose yokugijima ngemisebenzi ye-pvcreate.
-V , --version
Phrinta inombolo yenguqulo ekuphumeni okujwayelekile futhi uphume ngempumelelo.
Isibonelo
Qalisa ukwahlukana # 4 kwi disk yesithathu disk kanye ne-disk yesihlanu ye- SCSI yokusetshenziswa kamuva yi-LVM:
pvcreate / dev / sdc4 / dev / sde
