partitions are mapped to physical partitions, so if the size of the physical partition is 4MB, the logical partition size will also be 4MB. The size of the logical volume depends on the number of logical partitions allocated.Tools/Materials A server or notebook with a Linux operating system installed The virtual machine environment can also Method/Step To build LVM, you first need to prepare the disk or partition for LVM. If you use a disk partition as a physical volume, y
