No, Btrfs is deprecated in RHEL. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/7.4_Release_Notes/chap-Red_Hat_Enterprise_Linux-7.4_Release_Notes-Deprecated_Functionality.html Discussion here: https://lwn.net/Articles/729488/ https://news.ycombinator.com/item?id=14907771 https://access.redhat.com/discussions/3138231 If you want to use Btrfs in production, and have distribution support, you'd need to consider SUSE. If you want a similar feature set to Btrfs, but remain supported on RHEL, you'd need to discuss it with your Red Hat account manager. If upstream support for Btrfs is adequate then you'll want to use a recent stable kernel, and have a test and update strategy for balancing out the risk of incorporating new kernels as they're released vs the risk of using a fixed kernel version that grows stale over time. -- Chris Murphy
