When I built a filesystem on a software RAID-5 partition, I used: https://raid.wiki.kernel.org/index.php/RAID_setup#Calculation -scott ________________________________________ From: [email protected] [[email protected]] on behalf of Ken Teh [[email protected]] Sent: Tuesday, November 06, 2012 9:21 AM To: scientific-linux-users Subject: ext4 stride and stripe-width for a hardware RAID5 I'm wondering if anyone has tried using stride and stripe-width options when creating an ext4 filesystem on a hardware RAID5 array. Does it improve the performance of the array? Should you create the filesystem directly on the partition? What happens if you create it on a logical volume that is created on the physical partition? The LVM volume was created without options, ie, defaults. I know LVM supports stride and stripes as well but I dont know how they map to a physical RAID device so I've never bothered with it.
