That's what the error message would indicate, but UFS2 does support
xattr so that's a bit unexpected. Since I'm able to add a distributed
brick, I can rule out basic setup issues.
All the same, I can see via 'truss'
'Operation not supported’
Is anyone else using a similar setup (FreeBSD >= 11.1-RELEASE with the
official pkg) that has tested adding bricks in this way? Are there any
changes to the newfs or mount settings required for this to work that
