Just a note that the fix for the [missing memory barriers in the NetBSD virtio driver](https://gnats.netbsd.org/59618) has now been pulled into the stable NetBSD branches.

Just thought I'd give LVM a try on NetBSD. Note that approximately half of the disk space is used by Debian (most of it on logical volumes - and there is a bit of free space on the volume).
