It looks like built-in RAID didn’t land in this version, which means we’re another 3-5 years from anything that actually works like ZFS or btrfs which are LVM + RAID + filesystem.

According to the docs, you have to lay Stratis over MDRAID in EL8 to get storage redundancy:

    https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/managing_file_systems/managing-layered-local-storage-with-stratis_managing-file-systems

Snapshots with Stratis appear to work more sanely than in LVM2, so that’s something, at least.
