Well I could have searched a bit myself: it seems I am using the CFQ scheduler:
$ cat /sys/block/sda/queue/scheduler

So it seems that ionice is not doing its job properly. Any idea about why? This is the command I used to launch updatedb:
$ sudo /usr/bin/ionice -c3 updatedb

My /etc/updatedb.conf specifies a niceness of 10.
