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
