NAME

6       umount.nilfs2 - unmount NILFS2 file systems
7

SYNOPSIS

9       umount [-t nilfs2] [-dfilnrv] device | dir [...]
10
11       umount.nilfs2 [-nrv] dir [...]
12
13       umount.nilfs2 [-V]
14

DESCRIPTION

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

OPTIONS

22       See umount(8) for the full set of options.  Commonly used options  with
23       NILFS2 are as follows:
24
25       -V     Print version and exit.
26
27       -i     Don't call umount.nilfs2.  Valid for umount(8).
28
29       -n     Unmount  without writing in /etc/mtab.  This option must be used
30              carefully because mount.nilfs2 and umount.nilfs2 use  the  table
31              to store the process ID of nilfs_cleanerd(8).
32
33       -r     In case unmounting fails, try to remount read-only.
34
35       -v     Verbose mode.
36

THE LOOP DEVICE

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