when i'm in a pinch and want cleanerd to free up some space, i run:
# while true; do killall -HUP nilfs_cleanerd; sleep 4; done

each `HUP' signal causes cleanerd to both re-read config and run single pass.

i then monitor progress with
# iostat -dk 1 /dev/sda

to see if it is moving data around. if not, i lower `protection_period' in 
/etc/nilfs_cleanerd.conf; I usually have it set to 7 to 14 days on personal 
computers, but when /really/ in a squeeze for free space, i lower it to 24h.

you may also want to increase `nsegments_per_clean' in nilfs_cleanerd.conf to 
3 (but not much more; each segment causes up to 8MB of read and write upon 
each cleanerd pass).
