|
|
>Snapshots can be reinitialized. Reinitializing causes all of the
|
|
saved data to be erased and
|
|
starts the snapshot from the current point in time.
|
|
A reinitialized snapshot has the same
|
|
original, chunk size, and writeable flags as the original
|
|
snapshot.</P

|
><P
|
|
>To reinitialize a snapshot, use the <B
|
|
CLASS="command"
|
|
>Reset</B
|
|
>
|
|
command on the snapshot object
|
|
(not the snapshot volume).
|
|
This command reinitializes the snapshot without requiring you to
|
|
manually deactivate and reactivate the volume.
|
|
The snapshot must be active but unmounted for it to be reinitialized.
|
|
</P
|
|
><P
|
|
>This section continues the example from the previous section,
|
|
where a snapshot object and volume were created.
|
|
The snapshot object is called "snap" and the volume
|
|
is called "/dev/evms/snap."</P
