RAID0 in AWS cluster


Based on the best practices on the following page, I set up a 3 disk RAID0 array for MemSQL to use on my two leaf nodes (running on CentOS 7.6).

My question is: How do I tell MemSQL to use /dev/md0 (mounted in /data) instead of the root partition?

Also, I only configured RAID0 on the two leaf nodes. Should I configure it on the master aggregator as well?

Please let me know if you need any more details.
