Thanks for all the suggestions.
I had a look at systemtap but I have the feeling that in it's current state it is aimed more at kernel developers rather than average admins like me :-)
Still, I'll keep an eye on it also give the fact that there seem to be now new documentation being written about it
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/pdf/SystemTap_B...
On the other end, I have discovered blktrace and related tools, and this seems more palatable to me (subjective, I know ...). This example in particular seems to work for me
# blktrace /dev/sda -a issue -a complete -w 60 -o - | blkiomon -I 4 -h -
thought to share in case anyone finds it useful.
Can I use this to monitor which files are being written to disk?
