Thanks for replying!
This far:
vstr ~ # ps aux | grep nilfs_cleanerd
vstr ~ # cat /etc/nilfs_cleanerd.conf | grep protection_period
protection_period 600
vstr ~ # lscp
CNO DATE TIME MODE FLG NBLKINC ICNT

As you can see, the protection_period has passed a long time ago and
that the cleanerd won't start but produces errors.
