You would use the Linux software raid. Ignore the fakeraid that the MB calls raid. For striping you have your choice between raid0 (which is a misnomer since there is no redundancy) or straight LVM. Create a Volume Group, make each drive a Physical Volume in that Volume Group, then create a stripped LV. The advantage of this is that the striping is specific to the LV and any free space can be used for something else. Also, the drives don't have to be the same size. Obviously, any stripped volume could not be bigger than the smaller drive unless you added a third drive. You specify how may drives should contain stripes, you do not specify which drives should contain stripes. There is a difference if there are more than two drives (PVs) in a VG. All we need now is for LVM to get mirrors and life will get simpler than the existing md/lvm setup we have now. Read the LVM-HOWTO in the doc-linux-html package, and of course all the man pages. It seems complicated but it really is great. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
