NAME
umount.nilfs2 - unmount NILFS2 file systems
SYNOPSIS
umount
[-t nilfs2] [-dfilnrv] device | dir [...]
umount.nilfs2
[-nrv] dir [...]
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:
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.
