A possible work around is ZoL (ZFS on Linux) used as a GlusterFS brick.

For that matter, now that GlusterFS has checksums and snapshots, if
your workflow permits use a glusterfs only workflow (using SMB or NFS
for Windows or OS X, and the libvirt glusterfs backend for images) you
could build a conventional md/lvm RAID+XFS brick and then glusterfs on
that. And with distributed-replicated you can bail on raid6 and just
go raid 5. Heck if you have enough bricks you could do raid0 and just
let the bricks implode if need be.
