As I said on a previous mail I did boot it with a USB stick and cleared 
the glabel metadata and altered the fstab to point to both the GPT 
labels and the raw UFS device and I still get the issue. So am I right 
in thinking then that this has caused irreparable damage and the only 
way I can fix this now is to newfs the filesystem again, this time just 
using GPT labels and not using glabel at all?

This is the first time I've ever done a manually partitioned 
installation with GPT and alignment, previously I've only ever used 
sysinstall with non-aligned MBR installations, so it was a bit of a 
learning curve. If I do have to newfs it again then I want to be sure 
that I'm doing the correct things so that I don't find myself with any 
other issues. So does the rest of what I did look fine?

If it is clearly my own fault then the PR can obviously be closed and 
chalked up to learning!
