[NTLUG:Discuss] lv striping

Oracle recommends it.  Their paper #295 discusses it.  Part of their "SAME"
storage methodology.

Can I ask why you need a stripe size so large?  

and I'm really NOT trying to be argumentative guy... just wanting to
understand the root reason a little better...

I need to set up an lv that has a "stripe depth" of 1 meg.  I have looked on
google and the various man pages that I am aware of to no avail.

The only thing close I have seen is lvcreate -I (stripesize), but that only
appears to go up to 8kb.  I However, I may be mis-reading the man page.  It
says the number must be 2^n (2 - 9).  That could mean that a maximum of 512k
stripe size (hopefully the same as depth) could be achieved.  Either way,
that doesn't get me to the magical 1 meg level.

Also, what is the preferred method of disassembling an lv?

Any ideas?
