NAME

umount.nilfs2 - unmount NILFS2 file systems

SYNOPSIS

umount [-t nilfs2] [-dfilnrv] device | dir [...] umount.nilfs2 [-nrv] dir [...] umount.nilfs2 [-V]

DESCRIPTION

umount.nilfs2 detaches the NILFS2 file system(s) mentioned from the file hierarchy. This is the umount helper for NILFS2 to shutdown the garbage collector nilfs_cleanerd(8) before detaching the file system. Usually it should be invoked through umount(8).

OPTIONS

See umount(8) for the full set of options. Commonly used options with NILFS2 are as fol‐ lows: -V Print version and exit. -i Don't call umount.nilfs2. Valid for umount(8). -n Unmount without writing in /etc/mtab. This option must be used carefully because mount.nilfs2 and umount.nilfs2 use the table to store the process ID of nilfs_cleanerd(8). -r In case unmounting fails, try to remount read-only. -v Verbose mode.

THE LOOP DEVICE

umount.nilfs2 will free the loop device (if any) associated with the mount, in case it finds the option `loop=...' in /etc/mtab. The -d option, which also allows umount(8) to free the loop device without the `loop=...' option, is not supported.

AUTHOR

umount.nilfs2 is written by Ryusuke Konishi <@lab.ntt.co.jp> for NILFS2, based on the umount program included in the util-linux package.

AVAILABILITY

umount.nilfs2 is part of the nilfs-utils package and is available from http://nilfs.sourceforge.net.
