Some volume operations, such as expanding and shrinking, may require that
|
|
the volume be mounted or unmounted before you can perform the operation.
|
|
EVMS lets you mount and unmount volumes from within EVMS without having
|
|
to go to a separate terminal session.
|

</para>

|
|
<para>
|

EVMS performs the mount and unmount operations immediately.
|
|
It does not wait until the changes are saved.
