|
|
>The MD plug-in allows the child objects of a RAID region to be replaced with
|
|
other available objects.
|
|
This is accomplished using the general EVMS replace function.
|
|
Please see <A
|
|
HREF="evmsreplaceobjects.html"
|
|
>Chapter 22</A
|
|
> for more detailed information about how to
|
|
perform this function.</P
|
|
><P
|
|
>For all RAID levels, the replacement object must be at least as big as the
|
|
child object being replaced. If the replacement object is bigger than the
|
|
child object being replaced, the extra space on the replacement object will be unused.
|
|
In order to perform a replace operation, any volumes that comprise the
|
|
RAID region must be unmounted.
|
|
</P
|
|
><P
|
|
>This capability is most useful for Linear-RAID and RAID-0 regions. It is also allowed
|
|
with RAID-1 and RAID-4/5, but those two RAID levels offer the ability to mark objects faulty,
|
|
which accomplishes the same end result.
|
|
Because that process can be done while the region is in use, it is generally preferable
|
|
to object-replace, which must be done with the region deactivated.</P
