I'm thinking of buying a couple of disks to put in a striped array for performance. I already have a raid-1 array with mdadm. Are there are management or performance benefits of using mdadm raid-0 over using LVM striping? Im thinking along the lines of "LVM might be a better choice because I can have my striping (by adding another disk to the LV) and also have the added bonus of it being more 'manageable' than raid, because I can grow or shrink the LV". Is my idea full of holes? Are there well known issues; performance wise or manageability wise of using an LVM as a striped array for performance? Comments welcome --andrew
