</div>There in lies some of my confusion with this subject; correct me if I'm<br>
wrong in my understanding here: with LVM, I can keep adding more drives<br>
to a 'pool' and expand the size of the 'volume' that the OS sees<br>
available to it... but if any drive in that volume fails, I'd probably<br>
lose everything stored in that volume?!? Sounds like a somewhat risky<br>
business to me, unless you *really* needed a storage volume that big<br>
that you had to span multiple drives to do so.<br></blockquote><div><br>You are right. LVM sort of factors out the disk reliability issue. That's why you should consider to allow volumes that span across disks on RAIDed-1 disks only.<br>
