“In recent months, I have been boasting about how much Linux has
grown in its recent versions. Well, it’s true. We now have
journaling, we have clusters, and we have very nice SMP scaling.
It’s all in there. One more feature that should convince even
die-hard anti-Linux folks is the Linux Logical Volume Manager, or
LVM in short.”
“The LVM set of drivers/programs and documentation was written
by a team of developers with a website at
http://linux.msede.com/lvm/. As usual hundreds of people all over
the Internet contributed. … The goal of the LVM project was to
implement a flexible, virtual-disk subsystem to handle disk storage
and online allocation and extension/shrinking of said storage.”
“Most Unix-like systems now have the ability to break up
physical discs into some number of units. Storage units from
multiple drives can be pooled into a “logical volume,” where they
can be allocated to partitions. Additionally, units can be added or
removed from partitions as space requirements change. This is what
an LVM is good for.”
