If you want to use Auto Tiering for your databases, review the prerequisites, storage requirements, and other considerations for RoF databases and prepare and format the flash memory.

Use the prepare_flash script to prepare and format flash memory:

sudo /opt/redislabs/sbin/prepare_flash.sh

This script finds unformatted disks and mounts them as RAID partitions in /var/opt/redislabs/flash.

To verify the disk configuration, run:

sudo lsblk
