NAME

6       umount.nilfs2 - unmount NILFS2 file systems
7

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

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

THE LOOP DEVICE

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