NAME
nilfs_cleanerd - NILFS2 garbage collectorSYNOPSIS
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.
