net/glusterfs (currently at 8.4) is out-of-date.
Upstream has, in the 8.x series, new releases:
* 8.5 <https://docs.gluster.org/en/latest/release-notes/8.5/>,
* 8.6 <https://docs.gluster.org/en/latest/release-notes/8.6/>.
Upstream also has a new 9.x series, with releases:
* 9.0 <https://docs.gluster.org/en/latest/release-notes/9.0/>,
* 9.1 <https://docs.gluster.org/en/latest/release-notes/9.1/>,
* 9.2 <https://docs.gluster.org/en/latest/release-notes/9.2/>,
* 9.3 <https://docs.gluster.org/en/latest/release-notes/9.3/>.
I will try to do a patch for 8.4 -> 8.6, but have very little time.
(I would also offer a 9.x-series patch, but again, time.)
