i'm sorry that i wasn't more clear. i used to have raid0 with the siimage binary 
driver, but that is only for 2.4 kernels. so i've to use software raid and i 
didn't find the way how to put lvm on top of software raid. or how can i do it?
however, in suse admin guide is written about lvm: 'several hard disks can be 
used with improved performance in the raid0 (striping) mode.' any idea? can i 
use lvm as raid0? course, the best is raid and lvm on top, but if i can use only 
lvm, how fast it would be? can i check the speed?
thank you
