problem of stripe expansion !!!!!!!!!!!!!!!!!!!!!!!! </FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>
<DIV>You cannot expand stripe directly. You have to use</DIV>
<DIV>distribute + stripe, where you scale in stripe sets.</DIV>
<DIV></DIV>
<DIV>For example, if you have 8 nodes, you create</DIV>
<DIV>=> distribute(stripe(4)+stripe(4))</DIV>
<DIV>Now if you want to scale your storage cluster, you should do so</DIV>
<DIV>in stripe sets. Add 4 more nodes like this:</DIV>
<DIV>=> distribute(stripe(4)+stripe(4)+stripe(4))</DIV>
<DIV></DIV>
<DIV>Distributed-stripe not only makes stripe scalable, but</DIV>
<DIV>better load balanced and reduced disk contention.</DIV>
