Red Hat's statement on tech preview is here (I sure hope it doesn't require a login ...) https://access.redhat.com/support/offerings/techpreview >> The demand on the system is low and not likely to change in the >> near future, storage access speeds are not likely to be >> dealbreakers and it would be nice to not need to use LVM, btrfs >> seems to have a better feature set and more intuitive command set. >> But I'm uncertain about stability.

RHEL7.0 GA (released last May) has btrfs kernel code from v3.13. RHEL7.1 will have btrfs code from around v3.16. The stability of btrfs in RHEL7 releases depends heavily on the maturity and stability of upstream btrfs at the time of the release. IOWS, if btrfs around v3.13 crashed easily; there is nothing magical in RHEL7.0 to fix that. ;) -Eric -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
