What is LVM?
LVM is an acronym for “logical volume manager”, which under OS/2 has two related but independent meanings. The first refers to LVM.EXE, the file executed to install and manage IBM Boot Manager, create physical partitions, and assign logical volume letters to physical partitions. The second meaning refers to the enabling of OS/2 the operating system to recognize and access logical volumes. An LVM-enabled operating system includes OS2LVM.DMD, LVMALERT.EXE, and an LVM-aware version of OS2DASD.DMD in CONFIG.SYS, as well as an LVM-aware kernel. An LVM-enabled OS is not dependent on traditional drive letter assignment limitations. Linux LVM is a tool to dynamically manipulate native disk space available to installed Linux operating systems.
