Yes, create the RAID (MD) device, then layer LVM on top... Now, depeneding on your requirements, you may not need LVM (do you want/need snapshots, etc?) Also, how are you connecting these disks? How many IDE ports are you using? I would recommend against any sort of master/slave setup, as you'll have difficulties with failure detection and won't get the best throughput. - Herman On Tue, 21 May 2002, Dave Newman wrote: ->Hi -- -> ->I have four 160 GB IDE disks, and wanted to install software RAID 4/5 ->*and* LVM, and wanted to ask a couple of brief questions: -> ->a) Do I need LVM if I want to see a single partition (or can RAID do ->this for me)? -> ->b) Do I first install RAID, then LVM?
