nilfs_cleanerd - NILFS2 garbage collector


nilfs_cleanerd [-hV] nilfs_cleanerd [options] device [directory]


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.


-V, --version Display version and exit. -h, --help Display help message and exit. -c file, --conf=file Specify configuration file. -p interval, --protection-period=interval Override protection period with the specified number of seconds.


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.


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