Description Mark.Martinec 2018-11-19 14:22:24 UTC
In 12.0-RC1 two new zpool feature were introduced, but one of
them remains undocumented in the zpool-features(7) man page,
the 'large_dnode'.

# man zpool-features
search for 'large_dnode' or just 'dnode' - there is none.

This remains the case in 12.0-RC3.

Neither the new features nor how to enable them (and any possible complications / boot loader updates required for root pools) are not documented in the release notes [https://www.freebsd.org/releases/12.0R/relnotes.html] at this point, either.

+ Matt Macy who ported this feature to FreeBSD from ZoL.
