Echoing what others have said, sounds like XFS might be the best option if you can find a repository with a quality version (EPEL perhaps?) Interesting on the Backblaze and ext4 thing. While ext4 itself may support this larger file system size, I'm not sure if the "default" ext4tools will?? Could be a risk to investigate if you go this route. Other options I can think of: - btrfs (not sure if something like EPEL provides a release with this) - ZFS on Linux (for the adventurous only, but I believe they have a version that works well with RHEL). Personally, I'd go XFS. Ray
