RHEL advice would clearly be not to use btrfs.
I'm curious, is there anything in RHEL 8 that would replace BTRFS or ZFS? I'm experimenting with BTRFS on one system and the snapshot and subvolume features are nice.
I assume Stratis is the general answer.
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:

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