We seem to have filled the available space on the '/' partition of our NFS

the problem, and the space available on the other partitions:

If Im reading this figures correctly ('df -h' is much nicer) your / has
somewhere near 2,8 GiB and is full. Considering you have separate /usr
(which has only some 1,2 GiB) and /var this sounds fishy.
2,9 GiB for / with separate /usr and /var should be plenty. I'd suggest
looking into what is using all that space.
See if unused Linux images are installed
dpkg -l linux-*
Assuming 'un' means not installed, this looks ok:
server4:/# dpkg -l linux-*

You might want to check the output of
du / -hx --max-depth=1
To see where the 2,9 GiB are, but my bets are on /opt ;)
server4:/# du / -hx --max-depth=1

This doesn't suggest anything like 2.8GB, does it? (du does include
the content of sub-directories in its calculations, doesn't it?)
Your math was fine, but here's df -h for clarity
server4:/# df -h

/dev/md1 2.8G 2.8G 36K 100% /

md is raid1, and xfs. I tried fsck to see if there was some kind of
problem, but it refused to check an xfs filesystem. xfs_check,
itself, declined to run because /dev/md1 is mounted, and rw.
Running du to two levels reveals largest quantities for:
80M /etc
76M /etc/webmin
11M /root/.thumbnails
But there's nothing remotely approaching 2.8GB .
I'll try and look round the filesystem, I imagine xfs will log
something somewhere if it notices something wrong. I would like to
check the fs; if I recall, the system checks the xfs filesystem during
start up so, perhaps later today, I could take the system offline and
reboot it to force a check.
