Provided by: nilfs-tools_2.2.6-1_amd64 bug

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 follows:

       -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 <konishi.ryusuke@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.
