Should we use RAID or LVM if we have a filesystem which will expand in the future?

Solution Unverified - Updated -

Issue

  • We are currently setting up new storage to house an application that uses its own proprietary database, which grows slowly. We are trying to decide what the best approach would be to laying out the volume for it, using RAID or LVM with an ext4 partition to hold the data.

Environment

  • Red Hat Enterprise Linux
  • System contains storage for a large amount of data
  • Storage needs will grow over time
