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:
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.

I really want to upgrade to RHEL/Centos 8, but I need to keep using my
btrfs disk/partitions. Btrfs is very useful to me.
What can I do now ?
I guess a kernel on Centos 8, that supports btrfs, will be very popular
soon....
