LVM OLU\u015eTURMA<\/p>\n
\u00d6rnek1:<\/p>\n
sistemde 100GB \/dev\/sdb 150GB \/dev\/sdc \u015feklinde tan\u0131ml\u0131 olan iki
\ndiskten 250GBlik LVM olu\u015ftural\u0131m.<\/p>\n
1. pvcreate \/dev\/sdb (diskleri fiziksel olarak sisteme tan\u0131mlad\u0131k.)<\/p>\n
2. pvcreate \/dev\/sdc (diskleri fiziksel olarak sisteme tan\u0131mlad\u0131k.)<\/p>\n
3. vgcreate vg0 \/dev\/sdb \/dev\/sdc (vg0 isminde volume grup olu\u015fturduk.)<\/p>\n
4. lvcreate -L150GB vg0 (logical drieve olu\u015fturduk.)<\/p>\n
5. vgdisplay (olu\u015fan logical drive’\u0131 kontrol ediyoruz
\nve \/dev\/vg0\/lvol0 \u015feklinde olu\u015fan logical drive’\u0131 g\u00f6r\u00fcyoruz.)<\/p>\n
6. mkfs.ext3 \/dev\/vg0\/lvol0 (format at\u0131yoruz. istedi\u011finiz dosya sistemini kullanabilirsiniz.)<\/p>\n
7. mkdir \/mydisk (diski ba\u011flamak i\u00e7in bir dizin olu\u015fturuyoruz.)<\/p>\n
8. mount \/dev\/vg0\/lvol0 \/mydisk (diski buraya ba\u011fl\u0131yoruz.)<\/p>\n
\u00d6rnek2:<\/p>\n
\u015fimdi vg0 grubuna sistemde tan\u0131ml\u0131 olan 250GBlik \/dev\/sdd diskini ekleyelim ve bu diskin
\n120 GBlik k\u0131sm\u0131n\u0131 lvol0 logic driverine ekleyelim ve yeni alan\u0131 mount edelim.<\/p>\n
(Dikkat : bu i\u015flem s\u0131ras\u0131nda lvol0’In i\u00e7indeki bilgiler do\u011fal olarak kaybolur.)<\/p>\n
1. umount \/mydisk (\/dev\/vg0\/lvol0 \u00e7\u00f6z\u00fcyoruz.)<\/p>\n
2. fdisk ile \/dev\/sdd diskinin 120GBlik k\u0131sm\u0131n\u0131 \/dev\/sdd1 yap\u0131yoruz.<\/p>\n
3. pvcreate \/dev\/sdd1<\/p>\n
4. vgextend vg0 \/dev\/sdd1 (vg0 grubuna \/dev\/sdd1’i ekliyoruz.)<\/p>\n
5. lvextend -L+120GB \/dev\/vg0\/lvol0 \/dev\/sdd1 (lvol0 isimli logical drivera sdd1’i ekliyoruz.)<\/p>\n
6. mkfs.ext3 \/dev\/vg0\/lvol0<\/p>\n
7. mkdir \/mydisk (diski ba\u011flamak i\u00e7in bir dizin olu\u015fturuyoruz.)<\/p>\n
8. mount \/dev\/vg0\/lvol0 \/mydisk (diski buraya ba\u011fl\u0131yoruz.)<\/p>\n
\u00d6rnek3:<\/p>\n
Allah muhafaza \u00dcst\u00fcnde LVM kurulu yukar\u0131daki sistemin g\u00f6\u00e7t\u00fc\u011f\u00fcn\u00fc (i\u015fletim sisteminden kastediyorum.) d\u00fc\u015f\u00fcnelim.
\n\u015eimdi vg0 isimli disk gurubunu lvm kurulu olan ba\u015fka bir bilgisayara tan\u0131tal\u0131m.<\/p>\n
1. \u0130lk \u00f6nce sistemi g\u00f6\u00e7en bilgisayardaki \/etc\/lvm\/backup\/vg0 isimli yapt\u0131\u011f\u0131m\u0131z tan\u0131mlamalar\u0131n
\nkay\u0131tl\u0131 oldu\u011fu dosyay\u0131 bi yere kaydedelim.<\/p>\n
2. G\u00f6\u00e7en bilgisayar\u0131 kapat\u0131p diskleri \u00fcst\u00fcnden s\u00f6kelim ve \u00fczerine ismini yazal\u0131m. (\u00f6rne\u011fin : sdb)<\/p>\n
3. Bu diskleri \u00e7al\u0131\u015fan bir linux makinaya takal\u0131m. (D\u0130kkat diskin ismi yeni makinada hangi porta takarsan\u0131z onun ad\u0131n\u0131 al\u0131r.)<\/p>\n
Bu makinada tek bir ide disk oldu\u011funu d\u00fc\u015f\u00fcn\u00fcrsek diskin ad\u0131 hda olur.<\/p>\n
Bu makinada serial ata portu oldu\u011funu varsayarak port1’e sdb etiketli diski, port2 ye sdc etiketli diski, port3’e
\nsdd etiketli diski takarsak :<\/p>\n
Eski Makinada Yeni makinda<\/p>\n
sdb sda
\nsdc sdb
\nsdd sdc<\/p>\n
\u015feklini al\u0131r.<\/p>\n
4. Daha \u00f6nce kaydetti\u011fimiz dosyadaki bilgilere g\u00f6re yeni d\u00fczeni uyarl\u0131yoruz.<\/p>\n
5. \u015eimdi ilk iki \u00f6rnekte olu\u015fturulan vg0 isimli grubu tekrar olu\u015ftural\u0131m.<\/p>\n
pvcreate \/dev\/sda
\npvcreate \/dev\/sdb
\npvcreate \/dev\/sdc1<\/p>\n
vgcreate vg0 \/dev\/sda \/dev\/sdb \/dev\/sdc1
\nlvcreate -L270GB vg0<\/p>\n
6. Art\u0131k eski sistemdeki grubu yeni sistemde tan\u0131mlam\u0131\u015f olduk.<\/p>\n
7. mkdir \/myoldgrup (grubu ba\u011fl\u0131yaca\u011f\u0131m\u0131z bir dizin olu\u015fturuyoruz.)<\/p>\n
8. mount \/dev\/vg0\/lvol0 \/myoldgrup (logic s\u00fcr\u00fcc\u00fcm\u00fcz\u00fc bu dizine ba\u011fl\u0131yoruz.)<\/p>\n
\u0130\u015flem tamam! Hay\u0131rl\u0131 olsun. Sisteminizdeki verilerinizi kurtard\u0131n\u0131z. Bak\u0131n bakal\u0131m dosyalar yerindemi :))<\/p>\n
