--- Comment #4 from Nigel Babu <nigelb at redhat.com> ---
We have lots of space left on our existing machines. From Emmanuel on
gluster-infra@

That is the case: diskabel xbd0 says
#        size    offset     fstype [fsize bsize cpg/sgs]
 a:  19922881        63     4.2BSD   2048 16384     0  # (Cyl.      0*-   9727)
 b:   4194304  19922944       swap                     # (Cyl.   9728 -  11775)
 c:  20971457        63     unused      0     0        # (Cyl.      0*-  10239)
 d:  83886080         0     unused      0     0        # (Cyl.      0 -  40959)
 e:   8388608  24117248     4.2BSD   2048 16384     0  # (Cyl.  11776 -  15871)

NetBSD has some historic curiosity: c is the NetBSD partition in MBR, d is
the whole disk. This means you have 51380224 sectors of 512 bytes left after
partiton e: 24 GB.

Run disklabel -e xbd0 and add a f line:
 f: 51380161   32505856     4.2BSD   2048 16384     0

While there it will not hurt to resize c (for the sake of clarity)
 c: 83886017         63     unused      0     0

And still while there, fdisk -iau xbd0 to ajust NetBSD partiton size in MBR.

Then you can
newfs /dev/rxbd0f
add /dev/xbd0f in :etc/fstab
mount /dev/xbd0f
