It should also be noted that if you are using an enterprise linux distro, something like a "Linux 3.10" or an "e2fsprogs 1.42.9" from an enterprise linux has so many backports that it's going to be quite different from an upstream version. As a result, you're probably going to be better off seeking help from the enterprise linux's support desk, since they will be set up to help you much better than usptream developers. Also, there is a big difference between what an enterprise linux might support and a community distro. For example, even though Fedora has defaulted to btrfs, Red Hat Enterprise Linux has not decided to support btrfs. It was a techniolgy preview in RHEL 6 and 7, but it was fully removed in RHEL 8. So again, if you are using an Enterprise Linux distribution, you should really ask their support folks so you can get their advice, and find out what they will actually support. Cheers, - Ted
