I've run LVM on top of hardware raid (Areca SATA system with 8 drives in RAID-6) as well as LVM on top of software RAID-1 and RAID-5 (both IDE and SATA). LVM has been no less reliable in this configuration than in any other. IMHO, running LVM over RAID makes absolute sense. My preferred installation on a Linux box is to run s/w RAID-1 or RAID-5 with LVM on top and boot directly into an LVM root partition with initrd. I put a small (64MB) boot partition on each drive in the RAID array with an identical boot image and then any drive can boot into the kernel + initrd and start the RAID+LVM+root. I've never tried it with more sophisticated RAIDs such as your Fibre or SCSI As always, your mileage may vary, but [IDE|SATA]+[HW|SW]RAID+LVM has worked very well for me. - Roger > -----Original Message----- > From: linux-lvm-bounces@redhat.com [mailto:linux-lvm-bounces@redhat.com] > On Behalf Of Alexander Lazarevich > Sent: 19 September 2006 22:54 > To: LVM general discussion and development > Subject: LVM on RAID > > We have several RAID devices (16-24 drive Fiber/SCSI attached RAID) which > are currently single devices on our 64bit linux servers (RHEL-4, core5). > We are considering LVM'ing 2 or more of the RAID's into a LVM group.
