>2.3. Benefits of Logical Volume Management on a Large System</H1
|
|
><P
|
|
> The benefits of logical volume management are more obvious on large
|
|
systems with many disk drives.
|
|
</P
|
|
><P
|
|
> Managing a large disk farm is a time-consuming job, made
|
|
particularly complex if the system contains many disks of different
|
|
sizes. Balancing the (often conflicting) storage requirements of
|
|
various users can be a nightmare.
|
|
</P
|
|
><P
|
|
> User groups can be allocated to volume groups and logical volumes
|
|
and these can be grown as required. It is possible for the system
|
|
administrator to "hold back" disk storage until it is required. It
|
|
can then be added to the volume(user) group that has the most
|
|
pressing need.
|
|
</P
|
|
><P
|
|
> When new drives are added to the system, it is no longer necessary
|
|
to move users files around to make the best use of the new storage;
|
|
simply add the new disk into an existing volume group or groups and
|
|
extend the logical volumes as necessary.
|
|
</P
|
|
><P
|
|
> It is also easy to take old drives out of service by moving the
|
|
data from them onto newer drives - this can be done online, without
|
|
disrupting user service.
