nilfs_cleanerd - NILFS2 garbage collector

       Koji Sato

nilfs_cleanerd is part of the nilfs-utils package and available from https://nilfs.sourceforge.io.

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.

       nilfs_cleanerd displays its process ID (pid) to standard output when it started.

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-tnilfs2
              /dev/sdb1 on /nilfs type nilfs2 (rw,gcpid=PID)
              #kill-SIGNALPIDSIGHUP 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.
