Logical volume

A logical volume in the LVM concept is an allocated set of logical extents allocated from a volume group and is a concept analogous of a disk partition. A logical volume can be resized as nessecary without the need of reformatting and explicit copying of all its contents. A filesystem can be created on a logical volume the usual way, and can be mounted afterwards, just as any other filesystem.

Logical volumes are to seen as devices with names like /dev/VolGroup00/LogVolume00

Commands to manipulate logical volumes are:

• lvs
• lvscan
• lvdisplay
• lvcreate
• lvextend
• lvreduce
• lvrename
• lvremove
