<P><B>This HOWTO is deprecated; the Linux RAID HOWTO is maintained as a wiki by the

|
|
<P>While not described in this HOWTO, some useful tools for Software-RAID
|
|
systems have been developed.</P>

|
|
</H2>
|
|
|
|
<P>It is not easy to add another disk to an existing array. A tool to
|
|
allow for just this operation has been developed, and is available
|
|
from
|
|
<A HREF="http://unthought.net/raidreconf">http://unthought.net/raidreconf</A>. The tool will
|
|
allow for conversion between RAID levels, for example converting a
|
|
two-disk RAID-1 array into a four-disk RAID-5 array. It will also
|
|
allow for chunk-size conversion, and simple disk adding.</P>
|
|
<P>Please note that this tool is not really "production ready". It seems
|
|
to have worked well so far, but it is a rather time-consuming process
|
|
that, if it fails, will absolutely guarantee that your data will be
|
|
irrecoverably scattered over your disks. <B>You absolutely
|
|
<EM>must</EM> keep good backups prior to experimenting with this
|
|
tool</B>.</P>

|
|
|
|
<P>Remember, RAID is no substitute for good backups. No amount of
|
|
redundancy in your RAID configuration is going to let you recover week
|
|
or month old data, nor will a RAID survive fires, earthquakes, or
|
|
other disasters.</P>
|
|
<P>It is imperative that you protect your data, not just with RAID, but
|
|
with <EM>regular</EM> good backups. One excellent system for such
|
|
backups, is the

|
|
backup system.</P>
