what is meant by the term logical volume
For example, FreeBSD uses /dev/adaX (where X is one or more digits) to refer to PATA disks and /dev/adaXpY (where X and Y are both one or more digits) to refer to partitions on PATA disks. The term volume in Linux is related to the Logical Volume Manager (LVM), which can be used to manage mass storage devices. A physical volume is a storage device or partition. A logical volume created by the LVM is a logical storage device which can span multiple physical volumes. share|improve this answer.
