NAME

       nilfs_cleanerd - NILFS2 garbage collector

SYNOPSIS

       nilfs_cleanerd [options] device [directory]

DESCRIPTION

       nilfs_cleanerd is a system daemon which reclaims disk space of a NILFS2
       file system found in device.

       The optional directory argument specifies the  mount  point  where  the
       daemon operates.  It must be an r/w-mount.

       This  program can be invoked either automatically by mount.nilfs2(8) or
       manually by an administrator.  However, users are recommended to invoke
       nilfs_cleanerd  through  mount.nilfs2(8)  or  mount(8)  and shutdown it
       through  umount.nilfs2(8)  or  umount(8)  in  order  to   avoid   state
       inconsistencies among administration tools.

OPTIONS

       -c     Specify configuration file.

       -h     Display help message and exit.

       -n     invoke cleanerd without forking process. This option is intended
              for internal use from mount.nilfs2(8).

       -p     Override protection period with the specified number of seconds.

SIGNALS

       nilfs_cleanerd  reacts  to  a set of signals.  You may send a signal to
       nilfs_cleanerd using  the  PID  shown  by  the  mount  command  (or  in
       /etc/mtab):

              # mount -t nilfs2
              /dev/sdb1 on /nilfs type nilfs2 (rw,gcpid=PID)
              # kill -SIGNAL PID

       SIGHUP This  lets  nilfs_cleanerd  perform  a  re-initialization.   The
              configuration file (default is /etc/nilfs_cleanerd.conf) will be
              reread.

       SIGTERM
              The nilfs_cleanerd will exit cleanly.

       SIGUSR1, SIGUSR2
              Reserved  for  future  use.   These  let  nilfs_cleanerd  die at
              present.

FILES

       /etc/nilfs_cleanerd.conf
              Configuration      file      for      nilfs_cleanerd.        See
              nilfs_cleanerd.conf(5) for details.
