lvextend
Voorbeeld uitbreiden logical volume:
Met 400Mb: # lvextend -L+400M /dev/vg-one-100/vm-120-disk-1 # resize2fs /dev/vg-one-100/vm-120-disk-1 Tot 4 Tb: # lvextend -L 4T /dev/vg-one-100/vm-111-disk-1 # resize2fs /dev/vg-one-100/vm-111-disk-1
creeer fysiek volume
# pvcreate /dev/sda? # pvdisplay # pvscan
creeer volume group
Creeer een logical volume
# vgcreate dev-xen /dev/sda? (Kan ook bij de install) # vgdisplay
logical volume
Nieuw logical volume
lvcreate -L <size> (1T) -n <name> <volume group>
Voorbeeld:
lvcreate -L 8G -nkvm01 dev-kvm
Installatie verloopt met:
udell-kvm:~# apt-get install lvm2
Probleemoplossingen
Verwijderen volume group
Soms wil een volume group niet weg.
